Sorry to hear!!! I have a 6 month old puppy and I couldn't imagine. I just had his do-claws removed and he was nuetered, just seeing him in that pain makes me upset, couldn't imagine him getting killed.
BTW....most collars have plastice clips and they break when the dog pulls when on his leash. It's best to get a leather collar with a metal buckle. My parents dog pulled so hard that his broke....luckly it was in the front yard and there is never traffic on our street.
I know a few flashes that sell HEAVY duty collars with heavy hardware and heavy duty leashes with unbelievable hardware also. If anyone needs the info let me know.
