If you’ve ever had your dog slip a collar or back out of a harness, you know how scary it can be. And while harnesses are meant to be harder for dogs to wriggle free from than collars, some dogs are just escape artists at heart and need something more sturdy. Fortunately, there are harnesses for dogs that are virtually escape-proof—or at least more escape-resistant than others.
Note that every dog is different, and what works for one Houdini won’t necessarily work for another. There’s no such thing as an escape-proof harness that works for all dogs, just as no crate or gate can be perfectly escape-proof.
Our round-up takes into consideration a variety of needs and dog sizes to help you narrow down your options. Additionally, we’ve consulted a professional trainer and a veterinarian to learn exactly what dog parents should prioritize when choosing a harness for their escape artist.
Best Overall: Ruffwear Flagline Harness
When it comes to escape-proof designs, one of your first considerations should be a harness’s strength, says Dr. Sara Ochoa, DVM, a veterinarian at the Animal Hospital of West Monroe and co-founder of How To Pets. “A good escape-proof harness should be made of sturdy materials that do not break easily under pressure.” Nylon, leather, and neoprene stand out in this regard.
Additionally, Dr. Ochoa recommends looking for strong buckles that hold the harness in place, reinforced stitching, and escape-proof design elements, like dual leash attachments and double D-rings.
Ruffwear makes some of the most highly regarded harnesses in the industry. The nylon Flagline has a lot of features that make it especially useful for would-be runaways. First, the addition of a third belly strap effectively contains dogs who back out of traditional harnesses.
On top of that, the Flagline is highly customizable in size—a critical feature according to Trevor Smith, CPDT-KA, a certified dog trainer with Pupford. The more points of adjustment a harness has, the more snug and comfortable—and escape-proof—it will be for your dog. With six points of adjustment, the Flagline allows for a perfect fit that won’t let dogs easily slip out. As always, be sure to measure your dog to find the right size to start with.
For additional control, this harness has three leash connection points—two on the back, and one on the front. It bears mentioning that the front and furthest back tethers are made with fabric rather than metal, which is less ideal for especially powerful pullers. However, Ruffwear reports the fabric webbing loops are reinforced and can withstand some pulling. In any event, we recommend using these attachments in tandem with the back clip for extra security.
Features we like:
- 6 points of adjustment for a secure fit
- Lift-and-assist handle for dogs who need extra support
- Reflective trim
- Lightweight and less fabric than many other Ruffwear harnesses
- Available in multiple colors and six sizes
Things to consider:
- The front leash connection is fabric, not metal (although Ruffwear says they’ve updated this for added durability)
- Ruffwear gear is pricier than most
Best for Small Dogs: Gooby Easy Fit Harness
Sometimes dogs want to escape their harnesses simply because they’re uncomfortable to wear. An overly bulky and cumbersome harness may be too much for your tiny dog to handle.
“When it comes to smaller dogs, we’re talking lightweight and comfortable,” says trainer Trevor Smith. “And of course, we need it to fit appropriately to keep those little escape artists from making a great vanishing act!”
This neoprene Gooby harness has a relatively simple but effective design to earn its “escape-proof” label. The leash attachment on the back has straps that will cinch together if your pup tries to back out of it. With padding in the shoulders and a neoprene vest that’s tough yet comfortable, the Gooby is an easy-to-wear, comfy harness for your smaller dog.
The Gooby only has a single D-ring on its back. Many experts maintain this is preferable for smaller dogs to eliminate pressure on their delicate necks and chests. What’s more, this harness is trimmed in microsuede, so the edges don’t chafe. The step-in design means any sizing adjustments are on the back. And it’s machine washable—always a plus.
Note that this harness is designed for smaller dogs—even though the sizes go up to Large. The largest size is only rated for dogs like Pugs, Boston Terriers, and (slightly larger) Shibu Inus.
Features we like:
- Back strap and buckle contract the body of the harness when your dog pulls or tries to back out, so it hugs your dog
- Neoprene body is extra tough and water-resistant
- Buckle is made of the same plastic as seatbelt buckles
- Comes in several bright colors
Things to consider:
- Not for larger dogs
- Not for serious pullers (no D-ring on the front)
Best for Large Dogs: Rabitgoo Escape Proof Harness
Restraining a heftier pooch requires a focus on sturdy construction, Dr. Ochoa tells Rover. “A large dog with a strong pull may require a more durable, heavy-duty harness, compared to a smaller dog.” Equally important is a proper fit to ensure your dog can’t wriggle free. “It should fit snugly enough to prevent your dog from slipping out, but not be too tight that it will cause discomfort or restrict movements,” she says.
This escape-proof Rabbitgoo harness is constructed with durable polyester webbing, so it should resist your pup’s escape attempts. It also boasts five adjustable straps with three on the chest and belly for a dialed-in fit for your dog. With sizes starting at 19.7 inches around the chest and going all the way up to 43.3 inches, this one is better for medium to large dogs.
Trevor Smith adds that wide padded straps are beneficial for a larger dog’s comfort. The Rabbitgoo’s padded chest plate gently “hugs” your pup and equally distributes pulling force. Finally, your big dog will appreciate the padded air mesh for breathability during walks.
Features we like:
- Padded mesh material makes all the tough components comfortable
- Waterproof fabric
- Padded top handle for better control
- Bright reflective strips
Things to consider:
- With only one leash attachment in the back, it’s not for pullers
- Won’t work for smaller breeds
Best for Puppies: Chai’s Choice Double H Trail Runner
When it comes to containing puppies, comfort and fit should be top of mind. “Puppies need harnesses that can keep up with their growing bodies and boundless energy,” explains Smith.
Before you know it, your tiny pup will become a full-sized adult dog, so it’s all about customizable sizing. The right fit can make all the difference when it comes to preventing an untimely escape. Chai’s Choice accommodates the growing bodies of puppies with multiple straps that are easy to adjust as your dog grows.
Since puppies aren’t known for being delicate with their belongings, durability is also important—for both longevity and escape-proof-ness. This harness is constructed with sturdy canvas, and the D-ring is made with strong stainless steel to prevent an emergency breakaway. Comfort-wise, padded neoprene feels soft against your puppy’s coat, making them less likely to consider an escape in the first place.
Features we like:
- Third belly strap prevents escape
- Lightweight design is ideal for puppies
- Duraflex buckles add stability
- Dual D-rings aid help with pulling
- Reflective strips add to visibility
Things to consider:
- Supervise chewers: this is not chew-proof
Best for Seniors: Belpro Support Harness
According to Trevor Smith, comfort is the key to encouraging senior dogs to tolerate their harnesses. “We’re talking extra padding for those achy joints and harnesses that go on as easily as slipping on a cozy sweater.”
This Belpro harness features high-intensity polyester, which is durable yet lightweight. The inside is lined with breathable mesh, soft and comfy against your older dog’s body. Padding along the chest and belly panels prevents painful chafing.
Ease of use is another factor Dr. Ochoa recommends looking for. And while the Belpro’s multiple straps may look fiddly, many reviews report this harness is simple to put on and take off. There’s also a padded lift and assist handle, a nice bonus for times you need extra control, or whenever your senior dog needs a helpful lift.
Features we like:
- Five points of adjustment
- Three belly straps for enhanced escape-proofness
- Fully reflective material
- Durable nylon cloth and breathable mesh
Things to consider:
- No D-ring in the front means this isn’t the best choice for correcting pulling behavior
Best for Pullers: 2 Hounds Design Freedom No-Pull Harness
Walking a puller can be a drag—doubly so when you’re worried about a strong puller getting loose. If your dog pulls or tugs to get out of their harness, you’ll need extra tough components. Look for strength-rated clasps and fabrics that feature extra stitching, layers, and other reinforcing elements for escape-proofing.
The popular 2 Hounds Freedom model is one of the most frequently recommended harnesses among dog parents dealing with persistent pullers. First, it’s constructed with durable nylon and stainless steel hardware. Dual-ring connections (one on the chest and one on the back) make this perfect for training dogs who pull. It also comes with a double-ended leash to redirect pulling.
What’s more, four points of adjustment allow for a better fit to prevent escape. A noteworthy bonus of this harness is its martingale loop, which gently and safely tightens to prevent dogs from wriggling free. And lastly, soft velvet-lined straps make this a comfy harness your dog won’t mind wearing, so they may be more inclined to stay put.
Note that if you’re dealing with a pulling escape artist, a good harness can help a lot—but to maximize your and your pup’s safety and comfort, you may want to consider talking with a trainer too.
Features we like:
- Comes with a dual-ended leash for better control
- Minimal, lightweight design
- Multiple colors available
- Swiss velvet lining prevents painful friction
- Fits a range of dog sizes, from Shih Tzus to Saint Bernards

Best for Dogs with Short Hair: Sleepypod Martingale Harness
As we’ve pointed out, your dog may be trying to escape their harness because they’re uncomfortable. If your dog has a thinner coat or sensitive skin, Dr. Ochoa recommends choosing a harness made from a soft, breathable material that won’t chafe or rub their skin. Neoprene and mesh are both good options.
This lightweight Sleepypod harness is made from soft polyester and sports triple-layer mesh for breathability. It also uses strong Velcro rather than buckles, which eliminates friction that might otherwise irritate sensitive skin.
A unique escape-resistant feature is this harness’s martingale attachment. This helps keep your dog secure in their harness while gently discouraging pulling.
Features we like:
- Martingale loop enhances security
- Easy to get on wiggly dogs
- Breathable mesh
Things to consider:
- Best for small- to medium-sized dogs
Best for Dogs with Small Heads: Ruffwear Web Master Harness
Slender-headed dogs like Greyhounds, Whippets, and Salukis present a challenge when it comes to fitting a collar they can’t slip their heads out of.
The second Ruffwear harness on our list, the Web Master successfully accommodates the unique anatomy of sighthounds with a Y-shaped front. It also comes in a wide range of sizes and five adjustable areas to accommodate dogs with all types of bodies.
If you like adventuring with your dog but are afraid of an escape attempt, this one checks a lot of boxes. It has an additional belly strap, it’s built with sturdy polyester rip-stop, it’s padded and reinforced, and it has two leash attachment options: an aluminum V-ring and a webbing tow loop, plus a handle on top.
Features we like:
- Wide size range, including extra-extra-small
- Padding and covered buckles
- Reflective trim and a loop for attaching extra safety lights
- Durable materials and five adjustment points
Things to consider:
- Pricier option
- May not be the best for heavy pullers
