Man's best friend also needs protection from the sun's harsh rays. If you're planning to spend a lot of time outdoors with your dog, consider applying sunscreen to his snout. Since your dog's coat acts as a natural sun protection barrier, it's the non-fur areas -- like the snout and part of the underbelly -- that need SPF the most. But be sure to choose a sunscreen that has no zinc oxide. This chemical is toxic to animals, so check labels carefully. If you think your dog has a sunburn, give him a cool water-only bath and apply natural neem oil to the coat, which helps heal burns.
