The Boomer Ball is designed for those larger-than-life characters who love to chase and conquer - typically Bull Terriers and other 'macho' 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.Sizes. 4 inch = 110mm. 6 inch = 150mm. 8 inch = 200mm. 10 inch = 250mm
