I have a 10yo male Pitbull very well behaved. I have recently gotten an intact Pyrenees who is probably 7 or 8 months old. The pyrenees has been trying to show his dominance by attacking our Pitbull. The pit has just taken the abuse many times and walked away with bloody ears or a scratch on the head. The pyrenees did it again more aggressively a few days ago and this time my Pitbull had enough and unleashed fury on the pyrenees. I had to kick my Pitbull off. Thankfully no serious injuries other than the pyrenees limping for a couple of days and a damaged ego. Now the pyrenees is utterly afraid of the Pitbull and in no way wants to dominate him...and now the Pitbull seems like he's on the verge of unleashing fury on the pyrenees whenever they are around each other. Im afraid to allow them to be around each other without a chaperone. In many cases the pyrenees will retreat to our back pasture. Any suggestions on how to get these two to live in "harmony" and is my pyrenees going to be a useless wuss from his bruised ego when it comes to doing his job of protecting our livestock?
