I don't know how many of you were a part of this forum when I first got Bamm, but those that were may remember some of the stuff we were struggling with at that time. He was underweight for one thing. He had really bad DR especially onleash. He also kept freaking out with certain people, primarily men. He went after one of my male roommate's a few times and it was completely unprovoked. I did a ton of socializing with him and trying to get him used to new people. He improved a ton and the past couple years we haven't had any issues with him going after people save a few incidents. Those few incidents he was onleash so he wasn't able to actually reach the person he would try to go after but he would lunge at them on the leash and growl. I chalked a lot of it up to his past and lack of socialization in his original home especially since he improved so much with me working with him on it. Now I'm not so sure that's the case and wondering if there might be something more medical behind the way he sometimes acts? He has always been a bit sketch since the day I brought him home. He is great with me but with other people he can be fine one minute and the next minute he is giving whale eye and his whole body freezes up. I know Stef has mentioned being wary of him before though she does like him. Cristy is the only other Chazzer who really knows Bamm more and I'm not sure if she has ever felt uncomfortable around him or not? He is a great dog at home but his unpredictableness bothers me because he'll react fine with a situation but the next time freak about it and vice versa. For the most part its been easy enough for me to manage and like I said I've always worked with him on it thinking its more of a behavior related issue than anything. Recently he has gotten worse. I've noticed the past two weeks when I walk him he freaks out at every person he sees. A kid came walking up to us really fast last night and I pulled my dogs off to the side but Bamm lunged and tried to bite the kid as the kid walked past us. I can't have him trying to bite people and I may have to put a muzzle on him during walks until I get him to a vet. My boss did a behavior evaluation on him and she thinks I should definitely have a thyroid panel done on him. He was fine when he met her. But.. she walked out of the room and when she came back he focused real hard on her and growled. I'm worried about my dog. I don't trust him not to hurt someone right now. He has been totally fine with me and Josh. He has also been fine with my sisters.
