Does My Dog Need a Winter Coat? A Guide for US & Canadian Winters

Not every dog needs a coat – but many do, especially in a northern winter. Here's how to decide.

Dogs that usually need a coat

• Small and toy breeds such as Chihuahuas, Pomeranians and Yorkies lose heat quickly.
• Short, single-coated breeds like Dalmatians, Greyhounds, Whippets and Boxers.
• Low-to-the-ground dogs like Dachshunds and Corgis, whose bellies touch the snow.
• Seniors, puppies and dogs with health conditions, which regulate temperature less well.

Dogs that usually don't

Double-coated cold-weather breeds – Huskies, Malamutes, Samoyeds, Bernese Mountain Dogs – are built for it. A light waterproof shell can still help keep their coat clean in slush.

A simple temperature guide

• Above 45°F (7°C): most dogs are fine without a coat.
• 32–45°F (0–7°C): small, short-haired and senior dogs benefit from a sweater or light coat.
• Below 32°F (0°C): most dogs that aren't cold-weather breeds are more comfortable in an insulated coat.
• Below 20°F (−7°C) or with wind chill: keep walks short for vulnerable dogs, even with a coat.

Watch your dog, too: shivering, lifting paws, hunching or slowing down are all signs they're cold.

What to look for in a winter coat

• Chest coverage – a panel under the belly keeps snow off the most exposed area.
• Water-resistant shell – wet fur loses insulation fast.
• Leash or harness opening so you don't have to clip to the collar.
• Reflective trim for short, dark winter days.
