I use a 2x4 whenever my dogs need correcting, they jump up and I crack 'em in the head one good time and then twice in the ribs for good measure.
That aint shit. I use a 4X4 with nails sticking out. Ill knock a bitch out. Then pee on them to make sure they know im boss........... Not really, but I have put my hands on both of mines butt......
I always call Cesar Milan to strangle my dog into a calm submissive state.
