I have a 2- or 3-year-old Chow/Rottweiler cross that came from a shelter about three months ago. Gilly can be a very good dog. He is thoroughly housebroken, leads well, doesn't jump up or dig and is kind and gentle with my toddler granddaughter. However, anytime we go out for a walk or he is let loose in the backyard, he goes into prey-drive mode. He recently killed a feral cat in the backyard as I was unable to break his hold on the poor thing.
I am the alpha in the household and my husband is second and Gilly understands that. He minds me VERY well until he goes into prey drive, at which time he blanks out all else. Since I have no idea of his past other than what I have observed, I don't know if he was properly socialized as a pup, but any cat or other dog within his reach is in jeopardy. He is now wearing a muzzle whenever he goes out.
Is it possible that Gilly has become an adrenaline junkie from the surge that he gets from the hunt? He begins to drool when he sees a cat. We have two cats who now can't come into the house as long as Gilly is inside, which he is most of the time. I would like to be able to have the cats inside with him. I tried to socialize them when I first got him and it didn't work.
I also got a collar that sprays air to break his attention, which works unless there is a prey object close at hand. He can be a real problem on the leash if another animal approaches. His only other real problem is a fear of men in hats, and I think he may have been abused by one in the past. I went through a lot of effort to get Gilly as he was the cross I wanted, but got him from 1,500 miles away without actually seeing him. Does anyone have any suggestions?
