Here are some helpful tips from dogchannel.com on cold weather dog grooming:

Dog Winter Haircut

Some owners believe giving a dog a haircut — even breeds requiring regular trimming, such as the Poodle, West Highland White Terrier or Schnauzer — during cold weather compromises the dog because it needs its coat to keep warm. While dogs need to keep warm, it’s also true most pets don’t live outdoors all the time; they’re usually snuggled up with an owner in a centrally heated house. House dogs don’t need to rely on long fur and a thick undercoat for warmth as wild animals or sled dogs do.

It is all right to give your dog a haircut in winter. If you’re concerned about your dog’s being cold on outings, consider a longer trim or a doggie sweater.

Dog Brushing

For untrimmed dogs, an extra-thick winter coat needs regular, perhaps daily brushing. Some dogs look their best in winter because the coat is so thick and luxurious, but it can mean more work for owners. Keep your dog’s coat in top condition by brushing daily to remove tangles, dirt and dead hair, and to increase skin circulation and distribute oil.

A dog’s winter coat can hide trouble, such as lumps, bumps or sores, which is another good reason to keep brushing regularly. As you brush, feel and look carefully for signs of illness. Call your veterinarian if you see anything suspect.

Dog Nail Trimming

If your dog is indoors more frequently in the winter, the nails may need extra trimming because it’s not outside running and romping to wear them down. Check weekly, and once you hear that “click-click” on the bare floor, you’ll know it’s time to trim.
