Very cute and will help keep your pup warm. I ordered a large and it was a little baggy on my miniture daucshund Loki and she could step out of it the arms easy. A medium would have been better. It looks just like a human sweatshirt but at the end It is sewn to curv and cover the tail. There is a hole in the back of the neck so you can clip onto the collar. And even a hood that goes up over the dogs head. #rankboosterreview #Sponsored #Ollypet https://www.amazon.com/Ollypet-Clothes-Sweater-Chihuahua-Clothing/dp/B015QDUJVA
