LOL, just went thru this with Finn. Went thru 7 and (2 of them were my favorite training leashes). I am keeping Hallmark k9 in business! At 10 months he is finally growing out of it but when he gets in drive on the way to the training field he will still try and grab it. His bite is strong and he can go thru a leash with just a few bites. I have been redirecting with a ball and or tug and that is working out well. Try giving him something else to chew on and make sure you have a very strong leash to make sure he cannot break the buckle.
