So last night while setting up dinner, I accidentally stepped on my dog’s tail. I didn’t realize he was behind me and I didn’t know what was happening until I heard him yelp and scramble to get away from me. When I tried to go to him to apologize and to comfort him, I could hear a low growl coming from him. I thought everything would be fine by today, but this morning as I was heading out the door, he lunged towards me and was growling and barking. He didn’t bite or attack me, it seemed more like a lunge to instill fear or something. I know previously, the family that had him abused him. (I got him at the shelter) How badly, I’m not entirely sure, but I can assume it was bad because of how these recent events unfolded. Regardless, abuse is abuse. Anyways... I didn’t realize that this would trigger him to seeing me as the “enemy”? At this point, he doesn’t even come to me anymore, only my aunt. I can’t even go near him and now he just protects her. I don’t know what to do. Any advice?
