Frequently asked questions
- What measurements fit a dog coat or sweater?
- Back length from neck to tail base, chest girth, and sometimes neck size determine the size chart match. Measure on a standing dog with a soft tape.
- Why does my dog's coat size not match their harness size?
- Brands use different charts. Always compare your measurements to the specific brand table, not only S, M, L labels.
- Do double-coated breeds need coats?
- Many northern breeds overheat in thick sweaters. Use coats for short-haired, elderly, or clipped dogs in cold rain or snow, not as default for all dogs.
- When is cold weather a health emergency?
- Shivering, whining, or lifting paws in winter mean go inside. Hypothermia and frostbite need immediate vet care for small or thin-coated dogs.
