Tees, polos, long sleeved shirts are easy comfort for your yuppy puppy. Dog shirts are fun expressions of fashion as well as practical attire. They can help keep your dog warm if it's a little chilly but not cold enough for a coat or sweater. Dog shirts can help keep your dog's coat clean, keep him from shedding all over your house, keep his belly clean when out walking or playing in the yard, or even protect him from sunburn.
