Playing in the rain and mud can be fun. The Mudventure Coat ECO dog jacket is great because it helps to keep some water and dirt out of your dog's fur. And because it's un-lined, it's light and comfortable and ideal for travel, camping, or just for keeping in your backpack or purse. The raincoat is also practical in summer for dogs whose fur needs protection from windy, wet weather but no additional warming. This thin dog raincoat does not have a fabric lining but it is laminated with a soft, smooth waterproof membrane. The dog leash attachment opening can be snapped closed so that water does not run down the dog's back. And the waterproof rainstopper collar can be tightened behind the ears so water doesn't run down the dog's neck. Plus, the dog raincoat has fully taped seams
