With big dogs, there’s a lot to love. And a lot to handle on-leash! Big dogs can be extra-strong, and many pet parents find that a harness provides more control. Even if your large dog isn’t a puller, a harness can provide greater security and comfort on their daily walk. But it can be tough finding a harness that’s up to the task.
“The size and shape of large dogs vary widely,” explains Dr. Jennifer Sperry, DVM, Veterinary Advisor for Pets Plus Us. “Some dogs, like Greyhounds and Dobermans, have very deep chests, while others, like Mastiffs, have broad shoulders.” It follows that the best harnesses for big dogs will consider their unique anatomy, with features that cater to their impressive strength.
Focusing on your pet’s specific needs and body shape will help you choose the harness that’s perfect for them. To simplify your search, we spoke to the experts, weeding through scores of harnesses to find the most effective models for heftier hounds. We considered a range of big dog needs—so whether you need a no-pull harness, a mobility aid, or a rugged adventure harness, we have you covered.
Our picks
Best Overall: Ruffwear Front Range Harness
Ruffwear Front Range Harness
300-denier polyester ripstop, reinforced webbing, and foam-padded straps make this harness as tough as it is comfortable for large breeds in a range of sizes.
Pet parents looking for a large dog harness should prioritize sturdy construction, says Dr. Sara Ochoa, DVM, a veterinarian at The Animal Hospital of West Monroe and co-founder of How To Pets. “Large breeds tend to be strong and more energetic, so it’s essential to choose a harness that can withstand all their playful antics,” she explains.
From the highly-regarded Ruffwear line, this Front Range harness has a shell made with 300 denier polyester ripstop. Reinforced webbing along the chest adds to its durability. This harness is comfy, too: a mesh inner lining allows for breathability, and foam-padded straps prevent chafing.
Getting the size right is equally important, Dr. Ochoa points out. With four points of adjustment, the Front Range is able to accommodate a range of dog sizes. We also like that there are two leash attachment points—one on the front for better control, and one on the back for more casual walks. However, it’s worth noting that the front loop is made of fabric, not metal, so it may not be the best option for the strongest of heavy pullers.
Features we like:
- Straps distribute pressure evenly
- Includes ID pocket to store your dog’s tags
- Reflective trim improves visibility
- 10 colors available
Things to consider:
- Front attachment is fabric (not metal)
Best for Pullers: 2 Hounds Design Freedom No-Pull Harness
“Large dogs are often more powerful. When they pull at a harness, they’re at great risk of breaking the harness or injuring themselves,” says Dr. Sperry. For this reason, larger pullers need a harness that’s ultra-durable and features multiple leash connection points for better control.
The Freedom harness’s front and back clips make it a winner with big dogs who pull. A front or dual clip harness gives handlers more control over their dogs’ movements, reduces pulling, and makes training easier. As Dr. Sperry explains, when a dog pulls too much, these harnesses redirect their attention by turning them around to face their human, instead of allowing them to pull ahead.
You can use your regular leash alone with the front clip. Or you can use the included double-ended leash by attaching it to both clips for extra control.
Features we like:
- Martingale loop tightens gently to prevent escape
- Straps come in two widths to accommodate different dog sizes (⅝” and 1”)
- Velvet-lined straps prevent chafing
- The company offers a chewing replacement warranty
Things to consider:
- Included leash is only 4 feet (considerably shorter than most)
Best for Training: Rover Gear Better Walk™ No-Pull Harness
Rover Gear’s Better Walk™ No-Pull Harness is made with four points for comfortable adjustments and an ergonomic, padded Y-shaped belly strap. We think it’s a strong choice for beginners—both dogs and dog parents—who are learning the ropes, thanks to clear labels for fuss-free fitting and a nylon webbing design that makes sure you’re adjusting the harness evenly on each side.
Rings on both the back and the chest let you experiment to find the style that works best for your puller, or switch styles depending on the situation. Our testers found the flexibility a big help in training a new pup, and the foolproof design was a win for new pet parents.
Key features:
- Clear visual cues make it easy to fit to a large dog’s body
- Durable design reduces shock from pulling or lunging
- Front and back rings help dogs learn training/working mode vs. leisure/play mode
- Buckles are designed to reduce confusion or twisting of the belly strap
- Available in six sizes and four colors
Best for Hiking: Kurgo Journey Air Harness
The breathable material on this harness makes it a good choice for your large, active dog. It’s designed for running, hiking, and walking, and includes a back handle that gives you control when you need it—like when other dogs approach on the trail. The padded chest plate and mesh ventilation make the Kurgo Journey Air comfortable for longer wear on a hike. And the lightweight design means it won’t be burdensome for your dog while adventuring.
Features we like:
- Reflective trim for better visibility
- Quick-release buttons make it easy to put on and remove
- Rust-free hardware (ideal for dogs who love to swim)
- Front and back leash attachments
- Four points of adjustment
Things to consider:
- May not work for determined escape artists
Best for Escape Artists: Ruffwear Web Master Harness
Ruffwear Web Master Harness
The Web Master is a perennial favorite for large breed escape artists, since it comes with five adjustment points and two belly straps to prevent a dog from backing out.
For large Houdini dogs, Dr. Ochoa recommends choosing a harness with secure buckles, adjustable straps for a good fit, and security features like a martingale loop or additional belly straps.
The Ruffwear Web Master comes in a wide range of sizes with five points of adjustment to fit bigger dogs. It’s constructed with durable polyester rip-stop fabric and has two belly straps to prevent dogs from escaping.
Another consideration for escape artists is comfort, since some dogs will attempt a getaway because their harness is ill-fitting, stiff, or irritating against their skin. The foam-padded chest and belly straps make the Web Master a comfortable choice, making dogs less likely to try wriggling free. We also like that this harness has a padded and reinforced handle on the top for quick restraint when necessary.
Features we like:
- Two leash attachment points
- Five points of adjustment give big dogs the best fit
- Foam padding adds comfort
- Reflective trim
Things to consider:
- Pricier option
Best for Large-Breed Puppies: Rabbitgoo Escape Proof Harness
Rabbitgoo No-Pull Harness
Designed with two leash attachment points, this harness is made from durable nylon material with adjustable neck and chest straps to fit a variety of large breeds—including growing ones.
Since they’re new to wearing gear, puppies will benefit from a harness that’s soft and easy to get on. They also need a harness that’s adjustable for their growing bodies.
The Rabbitgoo was designed with larger dogs in mind. This harness evenly distributes pressure so your puppy’s frame is well-protected. With adjustable slide straps, you can easily customize the size as your pup gets bigger. Plus, it’s made from heavy-duty nylon for durability and has mesh padding to keep your puppy comfortable.
As a bonus, this harness is super affordable—meaning it won’t be too much of a sting if your puppy chews through it while you have your back turned for a minute.
Features we like:
- Padded mesh is breathable and comfortable
- Five adjustable straps
- Easy to put on and take off
- Built-in handle for extra control during puppy training
Things to consider:
- Won’t work for smaller breeds
- Only has one leash attachment on the back
Best for Seniors: BarkBay No-Pull Harness
BarkBay No-Pull Harness
Large senior dogs need comfort above all else, which this harness achieves with breathable mesh, four attachment points, and lots of padding.
For senior dogs, comfort and support will be top of mind. “If your dog has joint issues or other physical limitations, you may want to look for a harness with additional padding or support to help ease any discomfort,” says Dr. Ochoa.
This BarkBay harness features breathable mesh material to keeps your senior dog cool during walks. Four points of adjustment allow for a more precise fit, which helps comfort-wise. And there’s ample padding to prevent chafing. The BarkBay features two leash attachment points: you can use the front for pullers, or the back D-ring for more relaxed walkers.
Features we like:
- Rip-resistant nylon
- Quick-release plastic buckles are lightweight
- Leash clips are made with sturdy metal
- Includes ID tag pockets
- Multiple colors available
Best for Deep-Chested Dogs: ICEFANG Tactical Harness
ICEFANG Tactical Harness
Deep- and barrel-chested dogs can benefit from a wide chest piece with extra padding, and the metal buckles on this tactical harness are tested to hold against 1000 pounds of powerful pulling.
Dr. Ochoa reminds pet parents with large breeds to consider their dog’s unique anatomy. “Larger dogs often have broader chests and shoulders, which can lead to rubbing and chafing if the harness is not designed properly,” she points out. Accordingly, the best harness for barrel-chested canines will feature a wider chest piece that distributes pressure across a larger area. This will also prevent painful chafing.
This tactical harness has a generously sized chest piece with padding for comfort. Five points of adjustment make this harness customizable for your big-chested dog. The IceFang is designed for rugged outings with strong dogs. The metal buckles at the shoulders are tested to hold against 1000 pounds of pulling. And reinforced bartack stitching (narrowly spaced stitches) along each joint enhance its durability.
Features we like:
- Front and back leash rings provide control
- Top handle is large enough to grab easily
- Prevents friction and chafing
Things to consider:
- Some dogs may not like the extra coverage
Best for Extra-Large Breeds: Blue-9 Balance Harness
If a harness is too tight it can restrict movement, and if it’s too loose it may slip off. A poorly fitted harness can also cause chafing, skin irritation, or even throat or neck injuries, warns Dr. Ochoa. “It’s important to ensure the harness is correctly fitted and adjusted to your pet’s specific body shape,” she tells us.
To that end, giant breeds need a harness that’s highly adjustable. With six points of adjustment, the popular Blue–9 Balance allows for a customizable fit for bigger dogs. Fans of the Balance harness also appreciate that it doesn’t chafe their pet.
Additionally, broad-shouldered breeds like Great Danes and Mastiffs can benefit from a harness with a front-clip attachment, says Dr. Ochoa. This gives the handler greater control with the strongest pullers. With two leash attachments and durable materials, the Balance harness curbs pulling and distributes pressure evenly.
Features we like:
- Sturdy dual rings give you extra control if your giant dog pulls
- Design won’t restrict your dog’s movement
- Dual-colored straps make it easier to get on and off
- Prevents chafing
