I have a 11 mouth old lab, and he love to play fatch and he will catch anything you throw to him, but when we play fatch I have to put him on a long long chain because I will throw whatever I have and he will go after it but he sometime will bring it back and sometime he willl drop and take off the other way, and I wish I could just take him off the chain and play fatch with out the chain. can anyone help
