The canes have been great for our 6 month lab. He loves bully sticks but he's an quick eater who once swallowed a 5" long piece. (No damage done except the anxiety and the vet bill.) The cane gives him lots of chewing before we have to take away the last 6" or so. When we give him a new cane, we get an amusement bonus watching him maneuver through narrow spaces with the long cane. -- Roy
