Size guide
How to choose the right size dog harness
Choosing the right size dog harness is critical for your dog's comfort, safety, and well-being during travel. The harness should fit snugly while still allowing your dog to sit and lay down naturally. When correctly fitted, you should be able to fit two fingers between the harness and your dog. A harness that is too loose can cause your dog to slide or be tossed around during travel, increasing the risk of injury.
Measure your dog
You need to measure your dog to make sure that the harness you buy will be the right size. Wrap a tape measure around the base of the neck and the widest part of the chest, just behind the front legs.
