Benefits of using dog vests:

  • Improved mobility: A dog’s vest can help individuals with mobility issues or disabilities better control and manage their service animal while they are out in public or doing everyday tasks;
  • Enhanced safety: A harness can help ensure that a service animal is safe and secure while in public, and can help prevent the animal from running away or getting lost;
  • Increased visibility: An harness can help make it clear to others that the animal is a service animal, which can help reduce misunderstandings and potential confrontations and reflective strips increase visibility in the evening;

How to Pick the Correct Harness Size for My Dog?

Picking the right vest size for your dog is crucial because they will spend a lot of time wearing it, so the product should fit and be comfortable. To choose the correct option, all you will need is a measuring tape; size the girth (two fingers should fit between the tape and a dog’s body). Also, it shouldn’t be too tight around its neck and shoulders (if the skin bunches up, the harness is too small). Please choose a service dog vest extra small really for toy dogs.

You can find all sizes of leashes in the infographic below. Pay attention to the weight parameter, as it is often a key criterion:
