5. Look for tread wear
Thoroughly wipe your pet's paws and belly with warm water when she comes in, just in case she's picked up road salt, antifreeze, or other chemicals that she might lick off. (Salt can cause gastric distress in animals.) Also look for cuts from encrusted snow or ice, and remove ice balls from between footpads. Avoid using salt-based melting products on your own property; switch to sand, cat litter, or an animal-safe de-icer. Make sure you rinse and dry your dog's feet after every walk. Checking his paws regularly and trimming the hair between his toes (with blunt-ended scissors) will prevent frostbite.
