Our belly band is for comfort, style and will stay put. 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. 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.
