Choosing the right harness is only half the job, getting the fit right is just as important. A poorly fitted harness can rub, restrict movement, or allow your dog or cat to escape, which is the last thing any owner wants.
Measuring your dog or puppy correctly starts with the chest. Using a soft tape measure, wrap it around the widest part of the chest, just behind the front legs. This area is where most harnesses sit and gives the most accurate size. The tape should be snug but not tight, you should be able to slide a finger underneath comfortably.
For cats and kittens, the process is similar but patience is key. Measure around the chest just behind the front legs while your cat is calm. If your cat wriggles, take a break and try again later. A rushed measurement often leads to the wrong size being chosen.
It is also important to check the neck opening if the harness design requires it to go over the head. This helps ensure it will slide on comfortably without being too loose once fastened.
Once the harness is on, always do a fit check. You should be able to fit two fingers between the harness and your pet’s body. Watch how they move, their shoulders should move freely and there should be no rubbing under the arms or along the chest.
Signs a harness does not fit properly include chafing, hair loss, refusal to walk, freezing in place, or attempts to back out of it. Growing puppies and kittens should be remeasured regularly, as they can outgrow a harness faster than you might expect.
Taking a few extra minutes to measure carefully can prevent discomfort, reduce the risk of escapes, and make walks far more enjoyable for both you and your pet.
