Canine Winter Care
Groom your dog regularly. Your dog needs a well-groomed coat to keep it properly insulated during winter. Short- or coarse-haired dogs may get extra cold, so consider a sweater or coat. Long-haired dogs should have excess hair around the toes and foot pads trimmed to ease snow removal and cleaning. If you do the trimming, take care not to cut the pads or other delicate area of the foot.
