I tried searching but figured I would give the exact details of what is going on and seek your expert opinions on what I should do. I have a 10 1/2 week old lab/poodle mix (shown in the picture). My wife and I have had Bailey for about two weeks now. He is training great, already sitting on command, goes into his crate with no problems, allows me to put a leash on him with no problems, and even knows not to chew on anything other than his chew toys (this is accomplished with a "ehh" command when he starts to put his mouth on certain things, followed with very high and soothing "good boy" when he is chewing his toys). However, the last couple of days I have noticed a strange behavior. I let him out in our back yard to do his business, I have him on leash since our back yard is not yet fenced. He was trying to eat/bite at one of our plants (a Laurel) which I was not sure was poisonus or not. I gave him the "ehh" command, but he did not listen, so I gave a quick tug at the leash and he backed off. Then out of nowhere he came running at me growling and biting my legs, arms, etc... it looked like a full out attack. I tried to hold my ground and not back-off as he was doing this, but he did not back down. Since he was attached with a leash, I unforunitely had to pull him off of me and hold him away which I could clearly see was causing him pain since it look like he was choking. When he calmed down, I would say good boy, and pet him, and then he started at it again. I would get him to back off, we would go inside and he would act like nothing happened, and he would sit next to me for me to take his leash and collar off. He has had this type of behavior now two times against me and three times at my wife. What should I do? This does not happen everytime we go outside (never happens inside), but it has happened more than once. Seems to happen in the afternoon/evenings, not in the mornings.
