This winter my 5 year old border collie is experiencing an extremely dry nose. At times it cracks and bleeds a little, like human hands when exposed to harsh winter conditions. We live in the upper midwest, and we've experienced a colder than usual winter, which might be leading to this discomfort. I've added olive oil and coconut oil to the food to internally deal with the issue. I've also used coconut oil on his nose externally as a moisturizer. Any other suggestions? Thanks!
