Our labrador has destroyed more than one toy (including other kongs), he ends a bone cook beef 40 cm in 1 after noon but false squeaker stick resists worry has its intensive chewing. He loves us and bring it to the start, as he chewed quietly in a corner. Another game that our dog like: keep in his mouth while pulling it.
By cons, beware, it makes noise, AC whines everything goes (but precisely, the noise enormously love our young (18 months) dog, which make the toy squeak).
