Kong's Red Rubber Ball is pure fun. It's truly excellent at its chosen duty of bouncing, and is near indestructible.
Unfairly, the Kong Red Rubber ball is supposed to be for dogs rather than humans (Kong is an American premium pet products company).
Vets highly recommend the Kong Ball. Dogs happily chase it, they can't chew through it like a tennis ball, and the smaller one fits in a thrower.
Two sizes :
Smaller 6cm - for terriers, smaller poodles
Larger 8 cm is for labradors, kelpies, etc
