If your dog has a dry nose, it doesn't necessarily mean that he's sick. Dry noses are often a result of normal dog activities, such as lying in the sun, digging in the dirt or playing in snow or frost. However, if you see any additional symptoms, you should take your dog to see the vet. If there are no other symptoms, you can take care of your dog's dry nose at home.
Look carefully at your dog's nose. If there are any lumps, bumps, cracks or discoloration, you should consult your veterinarian.
Wash your dog's nose gently with some warm, soapy water and a clean cloth.
Apply a thin layer of petroleum jelly to your dog's nose. This will moisturize it.
Repeat Steps 2 and 3 twice each day until your dog no longer has a dry nose.
