Our 11 week old pup has started nipping, it is not cute we are not his chew toys. However his antics are not funny as he is really getting to aggressive. We were told to cry to act like it hurts to bring out compassion in him. That worked for only a couple days. We do not think he means this but he also is growling now, just learned his bark yesterday too! It is cute but should he be growling at his owners? Our last dobbie never behaved like this. I was told to show him who is dominant so we are trying. Any suggestions? I want to spank him but not sure if that is the right thing if I want him calmer. Breeder said to wait until 2 years to neuter him, but no way he has to much testosterone already! I do not want a biter! In all other aspects he is training well, listens(most of the time) and at 12 weeks tomorrow where should he be with respect, training etc. Anyone?
