The Puppia Soft Dog Harness is a real winner for comfort and is a best seller for your dogs.   IMPORTANT: Unlike human clothes, pet apparel designers have different sizing characteristics, so please do not purchase a Puppia harness based on the size of another manufacturer/designer. Also, just because your dog is small to you, does NOT mean it automatically fits a size small harness. You have to take various measurements into consideration before you purchase this harness. All dogs are built differently and some dogs have very deep or broad chest, whereas some dogs have a large head compared to their body. So please make sure you measure correctly and make sure your dog"s head can clear the neck opening of the harness, as this portion is NOT adjustable.
