How Often Should Sunscreen Be Put on a White Dog?

White dogs, particularly those with pink pigment on their noses and eye rims, are prone to sunburn. The risk for sunburn increases for shorthaired dogs or for dogs that have been shaved. When people are at risk of burning, they readily slather on the sunscreen. However, even people who realize that dogs are at risk of sunburn fail to consider sunscreen for the family dog.

  1. Sunscreen Lotions and Creams

    • Lotion or cream formulations should be used both frequently and regularly when they are out in the sun. According to veterinarian Carol S. Foil, "Sunscreen should be re-applied every 4 to 6 hours during the brightest time of the day from 10 a.m. to 3 p.m." Do not be afraid to skimp on the amount: Use at least three to four tablespoons spread evenly on a small to medium-sized dogs, and six to eight tablespoons on a large dog. Pay particular attention to the dog's nose, flews, ears, stomach and groin. If the dog's ear tips are white, apply lotion there as well.

    Sunscreen Spray

    • Avoid spray sunscreens for your dog, unless you have no other options. According to the Dog Sun Screen website, dogs breathe in harmful chemicals when sprayed with sunscreens, even those formulated for dogs. The dog's sensitive nasal membranes can easily be irritated by the chemical spray. If a sunscreen spray must be used, cover your dog's eyes and nose when applying it. Re-apply sunscreen spray on the same schedule used with lotion sunscreens.

    Around Water

    • Dogs, like humans, like to play in the water. Re-apply your dog's sunscreen if it has gotten wet or if it has gone swimming. Once your dog is dry, apply the lotion every four to six hours, as above.

    Human vs. Canine Formulations

    • Foil suggests that "sunscreen should be fragrance free, non-staining, and contain UVA and UVB barriers similar to SPF 15 or SPF 30 for humans." Some risks do exist when using sunscreens formulated for humans. Always choose canine sunscreen formulations if you have a choice. If canine formulations are unavailable, then sunscreen formulated for babies is appropriate for use on dogs. Sunscreens formulated for adults can cause your dog to become sick to its stomach if it licks it off its body. Read labels carefully for any warnings to parents. The same formulations that are hazardous to children will also be hazardous to a pet. Never use products containing zinc oxide. According to VetInfo.com, zinc oxide can cause anemia, nausea and chills if your dog swallows enough of it.
