9. Theres nothing better than hitting the beach with your puppy. But if powerful ultraviolet rays are detrimental to our skin, do they harm our pets as well? The answer is- yes, they do. Research has shown that dogs also get skin cancer and that a third of all tumors in dogs are sun-related! So be sure to apply sunscreen for dogs (our sunscreen contains a chemical that is toxic to dogs) that has a UV-busting strength equivalent to a human sunscreen of factor 15 (and it smells like coconut or vanilla, yum!).
