I can certainly understand where you are coming from as we are still working through this with Radar, he would randomly attack our 10 year old son. Just some suggestions from what I have learned the last 3 months and a few things to think about. Has there been a rabies shot lately? Radar's behavior started not long after his shot, and we did a homeopathic detox and after a couple of weeks could see change. We had a behaviorist come into the home and help out - that was eye opening - he pointed out that Radar didn't really have any rules and was trying to take over the home, if he would get excited about someone coming to the house we would pet him telling him it was okay to get excited/bark, which it wasn't we were reinforcing the negative behavior instead of disagreeing with it. we have worked on the leadership exercise's he suggested, and things like always eating something before him, making him sit and wait to get his food, petting etc. In the 2 weeks since he was there I have seen improvements in him he is listening to me again and taking cue's from us and seeing not only mom and dad as a leader but our 10 year old son as well.
I am by no means an expert, and I am not saying that all the change was the rabies shot (but he won't be getting another one without a titer test saying he needs it). You have gotten great advice but just a little about what we are going through as well.
It can be a long road but keep your head up and don't beat yourself up about what you did/didn't do in the past brush them off and start fresh with a new attitude, approach I think that is what I have learned most out of all of this - beating myself up for what was going on didn't do any of us any good.
