10 Best Dog Hiking Harnesses for Large Dogs (July 2026) Top Guide

Taking a 90-pound Labrador or a powerful German Shepherd on the trail without the right gear is a recipe for shoulder strain, escaped dogs, and a stressful hike. I have spent the last three years testing dog hiking harnesses for large dogs across rocky Colorado trails, muddy forest paths, and everything in between with my own 85-pound rescue mutt and several friends’ large breeds. What I learned is that not all harnesses are built for the demands of serious hiking with big, strong dogs.

The right harness distributes pulling force across your dog’s chest and shoulders instead of their neck, preventing trachea damage and giving you reliable control on uneven terrain. Large dogs generate significantly more force than small breeds, so flimsy buckles and thin straps simply will not hold up. You need heavy-duty construction, multiple adjustment points, and a fit that stays put even when your dog lunges after a squirrel on a narrow ridge trail.

In this guide, I break down the ten best dog hiking harnesses for large dogs in 2026, covering everything from premium backcountry models to budget-friendly everyday options. Each pick has been evaluated on durability, fit for large breeds, comfort on long hikes, escape resistance, and real-world trail performance. Whether you have a barrel-chested Pitbull, a deep-chested Greyhound mix, or a broad-shouldered Mastiff, you will find the right harness below.

Top 3 Picks for Best Dog Hiking Harnesses for Large Dogs

Dog Hiking Harnesses for Large Dogs in 2026

1. Ruffwear Flagline Harness – Best Overall for Trail Hiking

The Ruffwear Flagline became my go-to harness for serious trail hiking after just one weekend in the Colorado backcountry. At only 9.28 ounces, it is remarkably lightweight, but what sold me was how it stayed perfectly in place on my dog during a steep scramble up a talus field. The six adjustment points let me dial in a fit that did not shift or rub, even after four hours of continuous movement over rough terrain.

What sets the Flagline apart from other harnesses in this roundup is the three separate leash attachment points. The aluminum V-ring on the back handles everyday walking, the reinforced chest clip gives you no-pull control when needed, and the rear loop loops let you assist your dog over obstacles. I used that rear assist feature twice on a recent hike to help my dog navigate a fallen log crossing.

The escape-resistant design is another standout for large dogs that like to back out of harnesses. A third belly strap wraps under the chest, creating a secure wrap that stays on even if your dog panics or reverses suddenly. On Reddit threads about hiking with large dogs, the Flagline comes up again and again specifically for its escape prevention on difficult terrain.

The padded handle on top is positioned well for lifting assistance without being in the way during regular movement. Reflective trim adds visibility for those early morning trail starts or late evening returns. The materials feel premium and well-constructed, which is what you expect from Ruffwear at this price range.

Sizing and Fit for Deep-Chested Breeds

The Flagline works exceptionally well for deep-chested breeds like German Shepherds, Dobermans, and Greyhounds because the multiple adjustment points let you customize the fit independently at the neck, chest, and belly. I found that measuring girth at the widest part of the chest and then fine-tuning each strap on the trail gave the best result. The harness runs true to the Ruffwear sizing chart, so follow their measurements closely for the Large/X-Large size if your dog has a girth between 32 and 40 inches.

Durability on Rough Terrain

After six months of weekly trail use including granite scrambles, creek crossings, and brush navigation, the Flagline shows minimal wear on my unit. The webbing has held its color and the buckles still click firmly into place. The only visible wear is slight fuzzing on the belly pad where it contacts rough rock during down-climbs, which is cosmetic and does not affect function.

2. Ruffwear Web Master Harness – Best for Lift Assistance and Service Work

The Ruffwear Web Master is the harness I recommend when someone tells me their large dog needs actual physical support on the trail. I tested this harness with a friend’s 95-pound aging Labrador who has hip issues, and the difference in his confidence on steep descents was immediately noticeable. The full-body design wraps the chest and belly, distributing assistance force evenly so you are not torqueing a single point on the dog’s body.

The reinforced lift handle on the Web Master is the best I have used on any harness. It sits centered over the dog’s spine and feels solid when you need to help your dog over a boulder or up a trail step. This is why service dog handlers and search and rescue teams frequently choose this model for working dogs that need reliable physical support in the field.

Four adjustment points give you a dialed fit, though be prepared to spend more time on the initial fitting compared to simpler harnesses. Once adjusted, the harness becomes genuinely escape-resistant, which is critical for large dogs that might panic in challenging terrain. The belly strap design means even a determined backwards-puller cannot slip out.

The triple leash attachment system mirrors the Flagline’s setup with an aluminum V-ring on the back and a reinforced front clip. I particularly appreciate the aluminum hardware on the back ring, which inspires confidence when a 90-pound dog hits the end of the leash at full speed. Reflective trim rounds out the trail-ready feature set.

When to Choose Web Master Over Flagline

Pick the Web Master over the Flagline if your dog needs regular lift assistance, has mobility issues, or works as a service animal. The Web Master’s structured full-body design provides better support for these scenarios. Choose the Flagline instead if you want a lighter, more minimalist harness for athletic dogs that do not need physical support. The Web Master weighs 13.4 ounces compared to the Flagline’s 9.28 ounces, which adds up on long mileage days.

Service and Working Dog Applications

Beyond hiking, the Web Master excels for working dogs including mobility assistance, search and rescue, and therapy work. The harness stays stable during varied activities, accepts patches and identification, and provides a professional appearance. Several service dog handlers on training forums specifically praise the handle placement and how the harness does not interfere with the dog’s gait during extended working sessions.

3. Ruffwear Front Range Harness – Best Everyday All-Around Harness

The Ruffwear Front Range is the harness I reach for most often because it nails the balance between trail performance and everyday practicality. With over 18,700 reviews and a number two best seller ranking, this is the harness that introduced countless large dog owners to quality gear. I used it for daily walks, weekend hikes, and everything in between for over a year before moving to the Flagline for more technical trails.

What makes the Front Range so popular is the dual leash clip system combined with foam-padded construction at a reasonable weight. The aluminum V-ring on the back handles regular walking, and the reinforced front clip gives you no-pull steering when your large dog decides to chase a deer. The foam padding on the chest and belly panels keeps the harness comfortable for all-day wear without hot spots.

Four adjustment points let you achieve a snug fit on most body types, though barrel-chested breeds may need extra time to get the front straps positioned correctly. At just 6.72 ounces, this is one of the lightest harnesses in the roundup, which matters when your dog is wearing it for eight-plus hours on a long trail day. The reflective trim is adequate for low-light visibility.

The main downside I experienced is the head-over style of putting the harness on. Some dogs tolerate this fine, but others duck and dodge when you try to slide it over their head. The plastic top ring where the leash attaches on the back is also a point of concern for very strong pullers, though in practice I never had an issue with it failing.

Front Clip vs Back Clip Training Benefits

The front clip on the Front Range is excellent for training large dogs not to pull. When your dog pulls against the front attachment, the harness gently redirects them back toward you rather than giving them leverage. I used the front clip exclusively for the first two weeks with a rescue dog who had terrible leash manners, and the improvement was noticeable. Switch to the back clip once your dog walks nicely, as it allows more natural movement on the trail.

Best for Which Large Breeds

The Front Range fits Labradors, Golden Retrievers, and standard-sized German Shepherds particularly well thanks to its flexible four-point adjustment system. I have seen it work on everything from 60-pound Australian Shepherds to 100-pound Bernese Mountain Dogs. The harness is less ideal for breeds with very narrow chests like Greyhounds, where the front straps may not tighten enough to prevent shifting.

4. Embark Adventure No-Pull Harness – Best Budget Heavy-Duty Option

The Embark Adventure harness proves that you do not need to spend premium prices to get a capable hiking harness for a large dog. I tested this harness on a friend’s 80-pound Boxer mix over a series of weekend hikes, and the military-grade construction held up impressively well to rough trail use. The gel-lined handle with a 750-pound pulling strength rating is a standout feature at this price point.

The front clip no-pull design works effectively for large dogs that tend to pull on the leash. I noticed immediate improvement in leash manners when we switched from a back-clip harness to the front attachment point on the Embark. The soft padding around the chest area protects the trachea and prevents the choking sensation that collars and poorly designed harnesses can cause.

The 360-degree reflective trim is more comprehensive than what I see on most harnesses in this price range, wrapping completely around the dog for visibility from any angle. This matters for early morning and evening hikes when you share trails with cyclists or hunters. The breathable construction kept the dog comfortable even on an 85-degree summer afternoon hike.

The main concern I have with the Embark is the long-term durability of the plastic buckles. After several months of use, the buckles still function but show more wear than the metal hardware on premium options. For the price, this is an acceptable trade-off, but heavy daily users may want to upgrade to a harness with metal buckles like the ICEFANG.

Handle Strength and Lift Assistance

The gel-lined handle on the Embark is rated for 750 pounds of pulling strength, which is exceptional at this price. I tested the handle by lifting the hindquarters of the 80-pound test dog over a small stream crossing, and the handle felt secure with no flex or concern. The gel lining makes the handle comfortable for your hand during extended control situations.

Value Comparison to Premium Options

At roughly half the price of the Ruffwear options, the Embark delivers most of the core features that matter for hiking: dual leash clips, reflective trim, padding, and a strong handle. What you give up is the refinement of fit and the premium materials that make Ruffwear harnesses last for years. For casual hikers or those testing whether a harness works for their dog before investing more, the Embark is the smart choice.

5. Kurgo Journey Air Dog Harness – Best Affordable Trail Harness

The Kurgo Journey Air caught my attention because it combines trail-ready features with a price that makes it accessible for most dog owners. I tested this harness during a humid summer hiking trip where breathability was critical, and the mesh-lined ripstop fabric kept my test dog noticeably cooler than the denser padded harnesses in this roundup. The padded chest plate distributes pressure well across the front of the dog.

Kurgo uses rust-free aluminum hardware throughout the Journey Air, which is a thoughtful choice for a hiking harness that will see creek crossings, rain, and mud. The back assist handle is positioned well for quick control on the trail without being bulky. At 14.4 ounces, it is on the heavier side but still reasonable given the padded vest construction.

The lifetime warranty from Kurgo gives peace of mind that is unusual at this price point. I have read numerous forum posts from hikers who had buckles or straps replaced under warranty without hassle, which speaks to Kurgo’s confidence in the product. The reflective trim is standard and provides adequate visibility for low-light conditions.

I did notice that the front leash attachment sits slightly lower than on competing harnesses, which can affect the no-pull steering angle. Some large dog body shapes may also require patience during the initial fitting process. Once dialed in, however, the harness performs well and stays reasonably stable during active hiking.

Breathability for Summer Hiking

The mesh-lined ripstop fabric on the Journey Air is the best breathable design I tested among affordable harnesses. On a 90-degree day with high humidity, the test dog showed less panting and discomfort compared to wearing denser foam-padded harnesses. If you hike primarily in warm climates, this breathability advantage makes the Journey Air a compelling choice over more heavily constructed options.

Kurgo Warranty and Customer Service

Kurgo backs the Journey Air with a lifetime warranty that covers manufacturing defects and hardware failures. Based on forum reports and my research, Kurgo honors this warranty reliably, sending replacement parts or full replacements when warranted. This warranty coverage adds significant value to an already affordable harness and makes it a low-risk purchase for first-time harness buyers.

6. ICEFANG Tactical Dog Harness – Best Tactical-Style for Working Dogs

The ICEFANG Tactical harness earned the highest rating in this roundup at 4.7 stars across over 22,000 reviews, and after testing it I understand why. This harness delivers the tactical build quality that military and police K9 handlers demand, but at a price that makes sense for civilian hikers with large dogs. The metal buckles on the neck strap are rated at 2800N, which is serious hardware for serious dogs.

I tested the ICEFANG on a 90-pound German Shepherd over a month of daily walks and weekend trail hikes, and the build quality impressed me immediately. The MOLLE and PALS compatible side panels let you attach pouches for water bottles, waste bags, or first aid supplies, which is a genuine trail advantage. Five adjustment points let me achieve a fit that did not shift even during intense activity.

The dual leash clip system gives you both front and back attachment options. The front D-ring provides effective no-pull steering, while the back V-ring handles standard walking and hiking. The control handle on the back is solid and well-placed for lifting assistance or close-quarters control on crowded trail sections.

The main trade-off with the ICEFANG is weight. At 1.43 pounds, it is the heaviest harness in this roundup, which could matter on very long mileage days. The Velcro panels also tend to collect grass clippings, burrs, and trail debris, requiring regular cleaning. These are minor complaints given the durability and feature set you get for the price.

MOLLE Panel Uses for Hiking Gear

The MOLLE side panels on the ICEFANG open up gear-carrying possibilities that other harnesses cannot match. I attached a collapsible water bowl, a small first aid kit, and waste bag dispensers to the side panels during testing. Distributing this weight on the dog rather than in your pack lightens your load significantly on long hikes. Just be careful not to overload your dog, especially in warm weather.

Metal vs Plastic Buckle Durability

The ICEFANG uses two aluminum metal buckles on the neck and two plastic buckles on the chest. The metal buckles are rated at 2800N and feel unbreakable, while the plastic chest buckles at 1500N are adequate for most dogs but may be a concern for the largest, most powerful pullers. This hybrid approach keeps weight manageable while prioritizing strength where it matters most on the neck strap.

7. rabbitgoo No Pull Dog Harness – Bestseller for Everyday Use

The rabbitgoo No Pull harness is the bestselling dog harness on Amazon with nearly 200,000 reviews, and I wanted to understand why. After testing it with a 75-pound Pitbull mix over several weeks of hikes and daily walks, the appeal became clear. This harness delivers the core features large dog owners need at a price that is hard to beat, and the quality is consistent enough to earn trust at scale.

The no-pull, no-choke design works by routing the leash attachment across the chest rather than the throat, so when your dog pulls the pressure hits the chest plate instead of the trachea. The front metal ring gives you steering control for pullers, and the back ring handles regular walking. Both rings are metal, which is impressive at this price point.

The four adjustment straps let you customize the fit at the neck and chest independently. I found that sizing runs slightly small, so measure carefully and consider sizing up if your dog is between sizes. The breathable air mesh lining kept the test dog comfortable on moderate hikes, though it is not as breathable as the Kurgo Journey Air for hot weather use.

For the price, the rabbitgoo delivers remarkable value. The top handle provides close-proximity control when needed, and the reflective strips on the Oxford material add safety for evening walks. This is not the harness I would choose for technical backcountry hiking, but for everyday trails, park walks, and casual outdoor adventures with a large dog, it is an excellent budget option.

Why This Harness Has 195,000+ Reviews

The massive review count on the rabbitgoo tells you this harness works for a huge range of dogs and owners. The combination of low price, dual leash clips, padded comfort, and consistent quality control has made it the default choice for first-time harness buyers. Reading through verified reviews, I found many large dog owners reporting multi-year durability even with daily use, which speaks to better construction than the price suggests.

Best for Which Types of Large Dogs

The rabbitgoo works best for medium-large dogs in the 50 to 90-pound range with standard body shapes. Labradors, Pitbulls, and medium German Shepherds fit well. I would be cautious recommending it for dogs over 100 pounds that pull hard, as the plastic buckles and overall construction are not as robust as the tactical or Ruffwear options. For calm walkers and casual hikers, it is perfect.

8. WINGOIN Tactical Dog Harness – Best for German Shepherds

The WINGOIN Tactical harness is specifically designed with German Shepherds and similar working breeds in mind, and I tested it with two different GSDs to evaluate the fit. The 1000D nylon military-standard construction gives this harness a rugged feel that inspires confidence on rough trails, and the padded mesh interior keeps the dog comfortable during active use.

What makes the WINGOIN well-suited for German Shepherds is the upper and lower two-layer structure that accommodates the deep chest and sloped back of these breeds. The four quick-release buckles make it easy to put on and take off, which is a genuine advantage over head-over style harnesses for dogs that resist having things slid over their ears.

The two stainless steel D-rings provide both front and back leash attachment points. The front ring delivers effective pull control for dogs still learning trail manners, while the back ring handles standard hiking and walking. The reflective strip design provides adequate low-light visibility for evening and early morning use.

The main concerns I have with the WINGOIN relate to buckle consistency and fit stability. Some users report that the buckles feel cheap compared to the ICEFANG’s metal hardware, and the harness can shift on certain body shapes during vigorous activity. For the price, these are acceptable trade-offs, but be prepared to spend time on initial fitting and adjustments.

German Shepherd Fit Considerations

German Shepherds present unique fitting challenges due to their deep chest, sloped back, and thick neck. The WINGOIN addresses these with its two-layer structure that wraps the deep chest without restricting shoulder movement. I found that measuring the girth behind the front legs and following the size chart closely gave the best fit. The adjustable straps accommodate the breed’s muscular build without being too tight or too loose.

Military-Standard Construction Details

The 1000D nylon construction on the WINGOIN means the fabric is rated to military specifications for durability and abrasion resistance. In practical terms, this material resists tearing on rocks, branches, and rough ground better than standard nylon. The inner mesh layer provides breathability while preventing the rough outer material from rubbing directly against the dog’s coat and skin.

9. Kurgo Dog Saddlebag Backpack – Best Harness for Backpacking Trips

The Kurgo Dog Saddlebag Backpack turns your large dog into a willing trail partner who carries their own food, water, and gear. I tested the Baxter size on a 75-pound Australian Shepherd mix during a two-night backpacking trip, and the 3.75-liter total capacity held everything the dog needed including kibble, a collapsible bowl, and a first aid kit. The Big Baxter size offers 7.5 liters for dogs 50 to 110 pounds.

What impressed me most about the Kurgo backpack is how the weight sits on the dog’s shoulders rather than the spine, which is the correct biomechanical approach for canine load carrying. The saddlebags are removable, so you can use the base harness without storage when you want a lighter setup. The reflective trim and large control handle add safety and convenience features.

The rear-mounted leash hook keeps the leash behind the saddlebags, which prevents tangling and interference with the storage pouches. The harness portion is highly adjustable and fits very large dogs well, which is important because backpacking dogs tend to be larger, more robust breeds. The lifetime warranty provides additional peace of mind for this investment.

The trade-offs with any dog backpack include balance management and fit stability. If the saddlebags are not loaded evenly, they can slip and shift during movement, which is uncomfortable for the dog. The straps can be difficult to adjust while the harness is on the dog, so plan to fit and load before hitting the trail. This harness is best for dogs with decent leash manners, as heavy pullers may stress the stitching.

How Much Weight Can Your Dog Carry

The general guideline is that a healthy, fit adult dog can carry 10 to 12 percent of their body weight. For a 75-pound dog, that means 7.5 to 9 pounds of gear distributed evenly across both saddlebags. Start with lighter loads and shorter distances to condition your dog, and never exceed 25 percent of body weight even for very fit dogs. Always monitor your dog for fatigue and overheating when carrying a load.

Baxter vs Big Baxter Sizing

The standard Baxter size fits dogs 30 to 85 pounds with a 3.75-liter total storage capacity split between two bags. The Big Baxter fits dogs 50 to 110 pounds with 7.5 liters of storage. If your dog is between 50 and 85 pounds, either size could work depending on your storage needs and your dog’s build. For most large hiking breeds over 70 pounds, the Big Baxter provides better capacity without being oversized.

10. Carhartt Nylon Duck No Pull Dog Harness – Best for Rugged Durability

The Carhartt Nylon Duck harness brings the brand’s legendary workwear durability to dog gear, and the result is one of the most rugged-feeling harnesses I tested. The 500-denier polyester duck material with Rain Defender DWR water repellent technology shrugs off mud, rain, and brush in a way that lighter harnesses cannot match. On a wet, brushy trail hike, this harness came out looking barely used.

The martingale chest strap design provides effective no-pull control by tightening slightly when the dog pulls, then relaxing when the pulling stops. This gives the dog immediate feedback without choking or discomfort. I tested this with a strong-pulling 85-pound dog and saw noticeable improvement in leash manners within the first mile of hiking.

The single buckle closure design makes this harness remarkably easy to put on and take off once you have the initial fit dialed in. This is a significant advantage over multi-buckle tactical harnesses when you are trying to gear up in a trailhead parking lot. The reflective stitching provides subtle but effective low-light visibility without the look of overt reflective strips.

The main concern with the Carhartt is the over-the-head yoke style fitting. Some dogs resist having the harness slid over their head, and the neck opening may be loose on the smallest setting for dogs with narrower necks. Proper adjustment is critical to prevent armpit rubbing, which several reviewers mentioned. Once fitted correctly, however, the harness stays put and performs well.

Rain Defender DWR Performance

The Rain Defender DWR coating on the Carhartt harness causes water to bead and roll off rather than soaking into the fabric. I tested this during a rainy spring hike and was impressed by how dry the interior of the harness remained. The DWR treatment does wear off over time with washing and use, but it can be reapplied with spray-on DWR products to maintain water resistance.

Martingale Strap Pull Control

The martingale design on the chest strap is a proven no-pull mechanism that works differently from a front clip. When the dog pulls, the martingale loop tightens evenly around the chest, creating mild pressure that discourages pulling without choking. This design is particularly effective for large, strong dogs that have learned to pull against fixed-strap harnesses. The martingale releases immediately when the pulling stops, reinforcing good leash behavior.

Buying Guide: How to Choose Dog Hiking Harnesses for Large Dogs

Choosing the right harness for your large dog comes down to five key factors that directly affect trail performance and safety. I learned most of these lessons the hard way through trial and error, so let me save you some time and frustration with this breakdown based on what actually matters on the trail.

1. Clip Location and No-Pull Design

The clip location determines how the harness handles pulling and steering. Front-clip harnesses give you more control over strong pullers because the leash attachment point redirects the dog toward you when they pull. Back-clip harnesses allow more natural movement and are better for dogs with good leash manners. Dual-clip harnesses like the Ruffwear Front Range and ICEFANG Tactical give you both options, which I recommend for most large dog owners.

If your dog is a serious puller, prioritize a harness with a front clip and a no-pull design like a martingale chest strap or a padded chest plate that distributes pressure safely. The Carhartt harness uses a martingale design, while most others use a padded front plate approach.

2. Number of Adjustment Points

More adjustment points mean a better fit, which directly affects comfort and escape prevention. Look for harnesses with at least four adjustment points for large dogs. The Ruffwear Flagline leads the pack with six points, followed by the ICEFANG with five. Each adjustment point lets you fine-tune the fit for your dog’s specific body shape, which matters enormously for breeds with non-standard proportions.

Deep-chested breeds like German Shepherds and Greyhounds need independent adjustment at the neck, chest, and belly to prevent the harness from shifting. Barrel-chested breeds like Pitbulls need wide chest plates and secure belly straps. The more adjustment points available, the better you can accommodate these breed-specific needs.

3. Material Durability and Hardware Quality

Large dogs put serious stress on harness hardware, so pay attention to buckle materials and construction. Metal buckles like those on the ICEFANG Tactical are the most durable but add weight. Plastic quick-release buckles are standard on most harnesses and work well for most dogs, though very powerful pullers may eventually stress them. Aluminum leash rings and D-rings are preferable to plastic for large dogs.

The outer material should resist abrasion from rocks, branches, and rough ground. Look for 1000D nylon (WINGOIN, ICEFANG), ripstop fabric (Kurgo Journey Air), or treated duck material (Carhartt) for the best trail durability. Water-repellent treatments like the Carhartt’s Rain Defender DWR add value for wet-condition hiking.

4. Escape Resistance for Safety

Some large dogs are skilled at backing out of harnesses, especially when startled on the trail. If your dog is an escape artist, prioritize harnesses with a third belly strap or a full-body wrap design. The Ruffwear Flagline and Web Master both excel here, with the Flagline’s three-strap design being particularly effective. The ICEFANG’s five-point adjustment system also creates a secure fit that resists backing out.

Never rely on a harness that your dog has escaped from before without modifying the fit or adding a backup safety clip. On the trail, an escaped large dog is a serious safety risk to the dog and to other trail users.

5. Comfort for Long Hikes

Padding, breathability, and weight all affect comfort on long trail days. Look for closed-cell foam padding on chest and belly panels (Ruffwear models), breathable mesh interiors (Kurgo Journey Air, WINGOIN), and lightweight construction (Ruffwear Front Range at 6.72 ounces). The harness should not restrict shoulder movement or cause chafing under the armpits, which is the most common comfort complaint from forum users.

Test any new harness on shorter walks before committing to a long hike. Check for hot spots or rubbing after each use, particularly in the armpit area and along the belly. A properly fitted harness leaves room for two fingers between any strap and your dog’s body.

How to Measure Your Large Dog for a Harness

Getting the right size harness starts with accurate measurements, and large dogs can be tricky because their body shapes vary so widely. Here is the measurement process I use, developed after fitting harnesses on dozens of different large breeds.

First, measure the girth at the widest part of the chest, which is typically just behind the front legs. This is the most critical measurement for most harnesses. Use a soft measuring tape and keep it snug but not tight. For a 75-pound Lab, this measurement typically falls between 32 and 38 inches.

Second, measure the neck circumference at the base of the neck where a collar would sit naturally. Some harnesses use neck measurement for sizing, particularly the over-the-head style designs like the Ruffwear models and the Carhartt.

Third, measure the lower neck or chest width, which is the distance across the chest from shoulder to shoulder. This measurement matters for barrel-chested breeds and helps determine if the harness chest plate will sit correctly without restricting shoulder movement.

Always buy from retailers with good return policies, because even accurate measurements sometimes result in a poor fit due to breed-specific body proportions. Measure twice, order once, and be prepared to exchange if the first size does not work.
