Aggressive Great Dane?
I am concerned about the behavior of my 5 month old Great Dane puppy. We didn't get him until he was 3 months old, and he was pretty shy at that point. We have made a concerted effort to socialize him by walking him in public places, and he has taken a six week long puppy training course. He gets along well with our 2 year old uncut Golden Retriever, and my moms 6 month old Cavalier King Charles Spaniel. He is getting better about being around strangers, but still will growl and lunge every once in a while. He is awful around other dogs, however. Even the ones that he sees every week in class. He lunges, bares his teeth, and I honestly think that he would attack if we were to let him. He hasn't hurt anyone yet, but I'm terrified that he will. He is already 75 lbs, and I want to squash this before it becomes more of an issue. Everyone keeps telling me that it is just a puppy thing, and that it will resolve itself. I honestly think that it is more than that. What do you think?
