aggression

Submitted by Anonymous on Sat, 03/03/2012 - 22:25

I have had my 2 yr old pitt (goliath) since he was 6 months. I was 7 months pregnant when we got him. So goliath and Ethan are pretty much growing up together, ethan is now 18 months old and I have noticed when he tries to wrestle with goliath, the dog growls. This is the only aggressive behavior he displays toward ANYONE. What can I do to to stop my dog from ending up hurting my son? Any suggestions are welcome. Giving my pup up is up the last thing I want to do, but if it comes between choosing between the two of them I will choose my son.
