Actual aggression in a two month old dog is highly unusual, and a definite sign of bad things to come unless it is nipped in the butt immediately. I would highly recommend obtaining professional help from a behaviorist or dog trainer before Blue turns in a large adult dog with behavioral issues. In the mean times, do not interact with Blue if he shows any signs of aggression what so ever. You do not want him to mistake attention given to him as a reward. Typically I never recommend punishment since it is not as valuable a tool as positive reinforcement. However, in extremely young puppies such as these sometimes punishment can be effective. Once again, professional assistance is highly recommended in this instance. Hope this makes sense.
