From fit to fabric, choosing the right winter coat keeps your dog warm, safe, and comfy—learn who needs one and what features matter most.

Whether it’s downright fashionable or if you do it for your pooch’s warmth, a doggie coat may be just the thing to get through the winter!

Choosing the right winter coat for your dog involves balancing breed needs, precise measurements, and material functionality to ensure safety and comfort in cold conditions.

  1. Determine if Your Dog Needs a Coat

While northern breeds with thick double coats (Huskies, Malamutes) naturally withstand freezing temperatures, other dogs require external protection:

  • Small and Toy Breeds: These lose heat faster due to their higher surface-area-to-volume ratio.
  • Short-Haired/Thin Breeds: Greyhounds, Chihuahuas, and Vizslas lack the natural insulation to handle deep chills.
  • Seniors and Puppies: They often have compromised thermoregulation. Senior dogs with arthritis also benefit from warmth to maintain joint mobility.
  • Low-to-the-Ground Breeds: Corgis and Dachshunds are closer to snow and ice, making belly protection critical.

  1. Take Accurate Measurements

Avoid guessing sizes, as fit varies significantly between brands. Use a soft measuring tape while your dog is standing:

  • Neck Girth: Measure around the thickest part of the neck where a collar typically sits.
  • Chest Girth: Measure the widest part of the ribcage, just behind the front legs. Ensure you can fit two fingers under the tape.
  • Back Length: Measure from the base of the neck to the base of the tail.
  • Tip: If your dog is between sizes or has very thick fur, consider sizing up to allow for movement or layering.

  1. Match Material to Environment

Select fabrics based on diverse weather conditions:

  • Snow and Slush: Look for waterproof nylon or polyester shells with insulated linings like faux down or fleece to keep the dog dry and warm.
  • Dry Chills: Fleece or wool sweaters are breathable and provide excellent insulation for dry, cold days.
  • Wet/Rainy Winters: A lightweight, waterproof raincoat with a thin fleece lining prevents the coat from becoming heavy and cold.
  • Low Light: Ensure the coat has reflective piping or bright colors for safety during shorter winter days.

  1. Key Functional Features
  • Ease of Use: Choose coats with simple Velcro or buckle closures. If using zippers, ensure they have a fur guard to prevent snagging.
  • Harness Compatibility: Look for a leash portal or a built-in harness system to make walks seamless.
  • Maintenance: Prioritize machine-washable materials, as winter walks often involve mud and salt.
  • Mobility: The coat should cover the back and belly but must not restrict leg movement or interfere with bathroom breaks
