I have a lovely 3 year old basenji male that I have had since he was 7 weeks old, he was neutered at the youngest age he could be and we took him through basic obedience training at about 9 months old. A while ago when he was younger he bit me once while trying to give him a bath, he drew quite a bit of blood on that instance. That was prior to training, we used a trainer that is very well known in our area and trains most of the local police dogs, because of his attitude and not seeing me as a dominate person he suggested a prong collar. After that instance he has hardly ever shown severe aggression again… UNTIL NOW! Recently within the past several months (he has slept with us since he was 6 months old) he literally attacks our feet or legs in the middle of the night if we move, in an aggressive manner. He really hasn't been punished for it b/c we just fall back asleep and let it go. Next, let me say first that our B has NEVER shown aggression towards strangers or children, we socialized him from the get go, less then a month ago we stopped by a grooming shop for their grand opening, they were giving free nail trims. I usually do his nails myself and he has never had an issue. The groomer went to just pick him up and he jerked his head around and bit her, drawing blood on her hand. We didn't let that slide, she put a muzzle on him and continued. But it up set us terribly as we just handed him over knowing he has never done anything like that before. Also, last night we tried giving him a bath which he hasn't had a problem with since that one instance, as we were drying him off with towels which he usually likes, he went after our hands to bite us. Again today, I was going to trim his nails myself again like usual, however I tried and he went after my hand again, I couldn't even lift his foot without him snarling at me. I am worried because we truly love our dog more then anything, but this has to stop! PLEASE HELP!
