The Claim: Spray-on sunscreens for animals help lower your pet's risk of skin cancer.
Oz Says: It's true that dogs and cats, especially ones with light-colored or sparse fur, can suffer from sun damage. Trouble often happens on the ears, which are vulnerable to the type of skin cancer called squamous cell carcinoma. But research has yet to show that any kind of sunblock is effective for animals. And accidentally using a dog's formula on a cat can be dangerous; an ingredient in some dog products can be deadly to felines (plus, it's hard to imagine your cat sitting quietly while you sunscreen her—even with the right product!). Don't shell out $10–$20 for something that's not proven. Ultimately, experts say, the simplest way to protect furry ones is one of the same ways you keep yourself sun-safe: Whenever you can, choose the shade.
The Verdict: SKIP IT
