Hey all, we have found ourselves in an awful situation.... Our beloved dog Bandit bit my sister this afternoon as she tried to enter our home. Now to him, she is a stranger and did try to enter without our acknowledgement. But that's still no excuse to have a dog that aggressive around. If he knows you, he is the sweetest, most loving dog. But if he doesn't and you enter his property, he gets very territorial and aggressive. This is his second time biting someone that entered his property. A little back ground information on him, we had adopted him when he was 4 months old from the Salina animal shelter. It was said they just handed him over because they found out they were pregnant... But Since in our care, he has showed several signs of being abused in his former home. We love him and don't want to have to rehome him or even put him down, but he can't be this aggressive towards strangers. Does anyone know of a class to take him to that would teach him how to be protective in a not so aggressive way? He's almost 2. Thanks!
