Start with breed and coat: Although it’s important to apply sunscreen to any pup when they’re going to be out in the sun for long periods of time,
PetMD says doggie sunscreen is ESPECIALLY important for dogs with white or light colored fur and those with thin fur. For long-haired dogs, their summer haircut shouldn’t be too short because this can expose delicate skin to the harmful UV rays. As a rule of thumb, it’s ok to give your dog a summer trim, but make sure you cannot see your pup’s skin through their new haircut.
