One of our foster homes has decided she no longer wants to keep a dog. He’s an older guy, a bit creaky with arthritis and has recently been neutered and had a cyst removed. She tried to pet him while he was sleeping, he was startled and bit her. She freely admits it’s her fault but now she is “afraid” of a dog whom she formerly claimed to love. Really? One bite is all it takes. One of the on line training groups I belong to had an interesting post from a well known trainer. something to the effect of “expecting a dog never to bite under any circumstances is like expecting humans never to lose our tempers.” Since even the Dalai Lama admits to losing it sometimes, he is probably glad he isn’t a rescue dog.
