Yes dogs can get sunburned. And the sunburned areas can get nasty if they get infected (which most do since the area is itchy & the dog is constantly scratching). We use the Banana Boat Baby UVA & UVB Sunblock Spray Lotion as, in addition to being a gentle formula, it's hypoallergenic & waterproof. The spray works great to help you distribute a light coating along the body (most dogs don't like to be caked in stinky sunscreen & might lick it off if applied to heavily). When doing the head, face, & ears, spray some on your hands & rub it in being careful to avoid the eyes.
