What is a Y-Shaped Harness?
A Y-shaped harness, as the name suggests, forms a "Y" shape on your dog's chest. It consists of a strap that goes around your dog's neck and another that goes around their chest, just behind the front legs. These two straps are joined by a strap that runs down the front of the chest.
Pros and cons: Y-shape
Pros:
- Allows for a full, natural range of motion in the shoulders.
- Excellent for distributing pressure away from the neck.
- Great for active dogs that enjoy hiking and running.
Cons:
- It can be difficult to fit on some broad-chested breeds.
- Some dogs dislike the "over-the-head" action required to put it on
What is an H-Shaped Harness?

An H-shaped harness gets its name from the "H" shape it creates when viewed from the side. It has a strap that goes around the dog's neck and another that goes around the girth, connected by a strap along the back and another along the chest. This type of harness is known for being secure and easy to fit.
Pros and cons: H-shape
Pros:
- Very secure and often difficult for dogs to escape from.
- No "over-the-head" motion required.
- A good fit for dogs with narrow or slender chests.
Cons:
- The chest strap can sometimes sit across the shoulder points and restrict movement if not fitted correctly.
- Doesn't offer as much control for strong pullers.

How to choose the right harness for your dog

Now we’ve identified the fundamental differences, let's get into the practical side of choosing the right harness for your dog. As we all know, each dog is a unique combination of characteristics, so make sure your decision is based on their individual needs.
Consider breed and size
- For smaller breeds and dogs with narrow chests like greyhounds and whippets, an H-shaped harness can provide a snug and secure fit.
- For flat-faced breeds like pugs or French bulldogs, a Y-shaped harness can be a good option as it keeps pressure off the neck. However, ensure the chest piece is not too wide, as a poor fit may cause chafing.
- For deep-chested breeds like dobermans, a well-fitting Y-shaped harness is often the best choice as it will avoid restricting shoulder movement.
Consider age and energy
-
For puppies:
A lightweight and adjustable harness is essential. Both Y and H shapes can work, but a Y-shape is often preferred for encouraging good shoulder development. -
For active dogs:
If your dog loves to run and play, a Y-shaped harness allows for a full range of motion and gives them the freedom to express themselves. -
For senior dogs:
A harness that is easy to put on and take off is key. If they are not strong pullers, an H-shaped harness can be a good option.
How to fit your harness correctly
Regardless of whether you choose Y-shape or H-shape, the most important aspect of a harness is that it is correctly fitted. Otherwise, it can be uncomfortable, unsafe and easy to escape from.
The following recommendations apply to getting the right fit from both Y-shape and H-shape harnesses. Check out our sizing guide for more breed-specific guidance.
-
Adjust the neck strap.
You should be able to comfortably fit two fingers under the strap. This will make sure your dog is secure but doesn’t have their movement restricted.
-
Check the connecting straps.
For Y-shapes, the girth strap should sit a few inches behind your dog's front legs to prevent chafing in the armpits. For H-shapes, the neck and girth pieces should lie flat on your dog's back and chest.
-
Check the overall fit.
The harness should be snug enough that your dog can't back out of it, but not so tight that it restricts their breathing or movement.
Which harness do experts recommend?
A common consensus among experts is that a suitable harness, regardless of shape, must not cause any restrictions to movements your dog would naturally make - comfort is key!
- “Some harnesses cross directly in front of the shoulders, preventing natural movement, and you should avoid these.” - Dog Trust
- “Make sure it’s a harness that allows your puppy to walk and run naturally, as opposed to one that restricts the way they move.” - Blue Cross
- “Whether for everyday walks or focused leash training, a Y-shaped harness is a reliable and well-recommended option by trainers and veterinarians alike.” - PetsCare
- “The most important thing is that it fits your dog, and doesn’t cause them any pain or discomfort. Always make sure to look at the instructions and recommendations for your chosen harness or ask how it should be fitted when purchasing.” - Battersea
Finding the perfect fit
Ultimately, there is no ‘winner’ in the debate between Y-shaped and H-shaped harnesses. The best harness is the one that matches your dog’s unique body shape, supports their natural movement and personality.
If your dog is adventurous and active, the freedom of a Y-harness will match their needs. If your dog values comfort or is older, an H-harness is a good choice.
