Not every dog needs a coat, but some are glad of one. Short-haired, small, older or lean dogs often feel the cold more than thick-coated breeds. This guide covers when a coat helps and how to choose one that fits and stays comfortable.
Does your dog need one?
Dogs with thick double coats are usually fine in cool weather. Short-coated dogs, small breeds and seniors may shiver or want to turn back on a cold walk. Watch your dog's behavior, and if you are unsure, ask your veterinarian.
Types of gear
- Waterproof coats shed rain and wind, and some have a fleece lining.
- Raincoats keep the back dry in showers, and are usually light.
- Sweaters add warmth on dry days, but get wet and cold in rain.
- Reflective vests make a dog easier to see on dark winter evenings.
Getting the fit
Measure the length of the back from the base of the neck to the base of the tail, and the chest at its widest point. Compare these with the size chart, because sizes differ between brands. A coat should let your dog walk, sit and go to the toilet without restriction.
What to look for
- Easy on and off, with a fastener that works with gloved hands.
- Leash access: an opening for the harness clip.
- Coverage of the chest and belly without rubbing the legs.
- Machine washable fabric.
- Reflective trim for visibility.
Introduce it gradually
Let your dog sniff the coat, put it on for a short time indoors and reward calm behavior.
Care
Remove the coat indoors, check the skin under it for rubbing and dry it after wet walks.
