I bought this for a Chiweenie, but it was too big, so please use it for dogs around the size of a Dachshund or a Shiba Inu. I used it once for a short walk (about 10 minutes) and then washed it in the washing machine. It's easy to put on, just insert it under the dog's belly. Sunglasses are included as a bonus. #DogAssistiveProducts #DogSunglasses
