A dog coat or blanket includes a generally rectangular body section with chest and stomach straps extending from front and side edges respectively. The straps are adjustable so that a few sized will fit most domesticate dog breeds. Both the body section and the straps are two ply construction and the straps both secure the coat to the dog and cover a substantial portion of either the chest or the stomach to limit heat loss. The dog coat can be mounted on a dog from above merely by draping the coat over the dog and attaching the chest and stomach straps.
