Mastiffs are known to mature very slowly, mentally and physically. I am surprised when you said he is only 50-60 pounds? Is he a purebred Rottie? Most males are well over 120 pounds+. I would get him neutered, and then back to obedience class, you and him...and distraction. Yes, he could have killed the Yorkie. They do get jealous. We have a large dog with the small, but we have had to worry about the Yorkie attacking the Cane Corso....You need professional help. The Rotttie has pretty much been ruined from what it was intended for, and most now are just skittish and will bite first. I am sorry it happened, but now you know. Ridgebacks also can be agressive if not socialized and obedience trained. You have 2 strong willed breeds, be careful. |
