I love this doggy coat! It covers lots of things I like such as recycling (you use old cargo pants), pockets (two big ones),and it's practical (will keep your pooch comfortable). This creative pattern is from Instructables and shows you how to line the jacket to make it waterproof . Anything to cut down on wet dog smell is a good thing. Depending on the weather, those big pockets could be used for ice packs or fleece pads to help keep your puppy comfortable. Of course, they would work great for keys, a wallet, phone, and yes, of course doggy treats.
