J&J Dog offers dog obedience equipment for recreational use or AKC-approved competition, including regulation dumbbells. The AKC Regulations state that the dumbbell- which must be approved by the judge- will be made of one or more solid pieces of wood or non-wooden material similar in size, shape, and weight to a wooden dumbbell. We carry unfinished, coated with a clear finish, and plastic dumbbells in a variety of colors.
