If you normally have your pet’s fur clipped or shaved, keep the length longer in winter to keep your dog warm.
Nails may need more regular trimming since your dog is spending more time indoor on soft surfaces.
If you bathe your dog at home make sure he is completely dry before going out. You may even want to switch to a waterless shampoo for the winter.
Inspect the pads of your dog’s feet for signs of cracking or irritation. A pet-specific foot ointment will help condition the pads.
