The Boomer Ball is the perfect durable, hard wearing toy. It is virtually indestructible and is ideal for those ball-obsessed, toy destroyers; the larger-than-life characters who love to chase and conquer. The Boomer Ball is not intended for your dog to carry. The size selected should be larger than your dogs maximum jaw gape. It can also be used as a therapeutic toy to enrich the environment of elephants, pigs, polar bears or any other bored, inquisitive animal.
