Hello! Someone I know has a young amstaff. In my opinion he has failed to set clear rules and boundaries to this individual. This dog will basically do what ever he wants. He will jump on the sofa if he likes to etc.. I dont consider him aggressive though, just very dominant. So when guests arrive to this appartment, this dog likes to hump their legs and jump on them. Maby even try to nip a little from your arm or leg. None of this is especially aggressive, but very persistant. What I have tried to do is I push the dog away with my leg. Amstaff is a pretty strong dog, and you need to use a lot of force if you start to wretle with one. Sometimes he chooses another wictim after I push him away again and again.. sometimes I need to call the owner which then will lock him in a cage for a while.. Most of the info on dogs I find on the net is written as a guide for the owner. If I was the owner of this dog Im sure I could set him straight. What I dont know is what can I do when someone elses dog acts dominant ? The thing is that in order to get this dog realize his not the boss, I would need to hurt him most likely. And because Im not an experienced dog trainer, I would most likely need to use some sort of weapon with such a strong dog. Is there any other way to deal with this behaviour ?
