Are dog winter coats waterproof or just warm?
Both styles exist. Some coats are insulated for warmth alone, but others add a water-resistant or waterproof outer shell to block rain, snow, and wind. If you are looking for water protection, check the description to see if there are water-resistant or waterproof claims, look for tightly woven nylon or polyester shells and details like sealed seams, and match the insulation level to your climate so your dog stays comfortable.
How do I clean and maintain a dog winter coat?
Follow the care label for your product. Often the instructions are to brush off hair and dirt, close all fasteners, and wash on gentle in cold water with mild detergent. Air dry flat and away from direct heat. Usually, you'll want to avoid bleach and fabric softeners, and spot clean salt or mud right away to prevent damage and odors. If the outer fabric has a water-repellent finish, you can refresh it with a spray treatment after several washes. Store the coat clean and fully dry to prevent mildew.
