Ok, well the other day we had planned a private lesson with a trainer who we were told was excellent, and I wanted to try some obedience with Rex, well the class didn't go to well Rex was scared to death of him... He even growled at him, and when he asked me if he normally growled at home, I said no and he was surprised. Rex loves people but he was scared to death of that trainer and the trainer just kept choking him. Now rex is used to a choke chain but¸never used like that I feel super bad because now he sticks to me and my mom and dad like crazy and he gets so scared easily). To make it worse the other night my parents were arguing, (he came down like always) to find me and started crying at the bathroom door, then he went to lay under my bed and got stuck and cried, and cried it took us quite a while to get him out. And yesterday we took him to my grandparents house, and he's suposed to stay out in there porch, and my normally happy go lucky I love life husky, was scared to death, he would keep coming in the kitchen and hiding under the table. I did put my sweater for him to lay on and thankfully that quieted him down a bit. Everyone is noticing the difference in his behaviour, what can I do so he goes back to his old self?
