Using your FITS dog coat is easy. Just put it on your dog like a regular jacket. Make sure to adjust the elastic neck with the toggle for a snug fit. When you're using a leash, use the leash access hole. As for maintenance, you can machine - wash the coat in cold water. Don't use bleach. Hang it up to dry. Avoid leaving the coat in direct sunlight for too long as it might fade the colors. Always check the coat for any signs of wear and tear, and if there are any loose threads, you can sew them up easily.
