Alfie Pet by Petoga Couture - 4-Piece Set Jacob Denim Belly Band for Smaller Breeds - Color: Denim and Light Blue (for Boy Dogs) Please note that this belly band is specifically designed for smaller breeds. Size Medium fits waist 10" - 12.5" (5.75" wide). For belly bands you want to take the girth measurement at the waist (in front of the back legs). Sizing for each dog is unique. We highly recommend you measure your pet precisely with a flexible tape measure to ensure the best fit. Contact us if you have question. We are happy to help. Alfie Pet's belly bands are for boy dogs who leg lift, mark, dribble and urinate indoors. The closure is constructed with industrial strength velcro for a secure fit. Our belly band is for comfort, style and will stay put. Belly bands are made to prevent dogs from marking their territory when out and about. These belly bands are not intended to absorb pee, but to inhibit peeing. For urine absorption, just add a panty liner or tissue. Belly bands are not only a good training aid but they also work as an anti-breeding aid for male dogs that are not neutered. They are also ideal for travel in the car or on a plane or in dog friendly stores and restaurants. They also provide temporary aid to dogs with incontinence problems. Best of all, they deliver peace of mind with your beloved companion, even if he's not perfect in manners. Alfie is a registered trademark and is exclusively distributed by Petoga Couture.
