I was letting Gunner out of his crate this morning for his potty time. As he was stepping out of his wire crate, somehow a few of his toes got hung in the bottom portion that goes over plastic tray. He started screaming and yelping like crazy. I reached to try and help him get his foot loose, and then he started getting very aggressive acting. The yelps turned to snarls and he actually bit my arm as I was trying to pry his foot loose. Honestly, I didn't realize until after I got him free that he had bit me beacuse I was so focused on getting him loose, but he broke skin and there is already a bruise there. After I got his foot loose, he cowered to the back of the kennel and refused to come out. I didn't push him or say anything, I just left the door open and within five minutes, he ventured out on his own. When he did, he was very quiet and came up to be me very warily. I petted him and then he turned into his happy goofy self. Now he's running around like nothing ever happened and is treating me the same as always. Two questions. Should I be concerned about the bite or chalk it up as a freak accident from a scared and hurting pup? I know he was terrified...he even peed all over both of us. Should I worry that he associated the pain with me? That's how he acted. Like he thought I was the one hurting him. I obviously don't want him to think that I would EVER hurt him or not trust me. Help....this was a weird freak accident but I don't want it to hurt our relationship which has been perfect until this point. BTW, his foot is fine. Not even limping.
