Too many toys just can't take the strain! The Boomer Ball is designed for those larger-than-life characters who love to chase and conquer - typically Bull Terriers and other 'macho' breeds, also a great option for herding breeds. It is designed not to be picked up by the dog, so should be a size bigger than the dog can carry. It can also be a therapeutic toy to enrich the environment of elephants, pigs, polar bears or any other bored, inquisitive animal. colour chosen at random
