Winter brings cold and snow and ice and salt.
Running around in the snow is fun, however, keep an eye on your dogs feet for ice buildup. It can accumulate and cut into the dogs skin between their toes.
Trimming your dogs hair and spraying your dogs paws with a non-stick cooking spray can help with preventing buildup.
