This is extremely dangerous behaviour and something which must be corrected ASAP. If you don't get it under control now it will likely get much worse as he ages.
The next time he does it, grab him by the back of his neck, the scruff as we call it. Pick him up, by the scruff (you won't hurt him), turn him so he can see your face, tell him NO, Bad Dog and then put him in his crate. Do this every time he gets nasty. I will get right in the dog's face when I tell him/her NO. You must use a very forceful voice, that is not to say scream at the dog, just loud, controlled, forceful.
Never allow agressive behaviour to go uncorrected, if you do you are telling your dog it is OK !. Personally I allow a dog to bite me once, if he bites me twice he's gone. A dog that will bite it's master is one you cannot trust around people and I won't have that kind of animal in my home.
Good luck. |
