Just like us humans, we use sunblock to protect ourselves from harmful UV rays and to reduce this risk of developing skin cancer. Skin cancer is common in dogs and is highly preventable. Don’t be afraid to put sunblock on your dog where they have less hair coverage. Cover their bellies and around the ears. It can be reapplied every three to four hours or after playing in the water for best protection. Avoid pet sunblock products that contain zinc oxide, because this is an ingredient that may be toxic to your pup. Always read the label before buying.
