The cat thread reminded me.
My dbf told me at the weekend that his uncle has a new jack russell and is going to dog training as the dog is growling and snapping at people.
Apparantly the dog trainer has told him to roll up a newspaper and smack the dog on the nose when it growls.
I think this is complete bull, I remember dong dog training quite a few years ago I admit and we were told never ever to hit as this will make the dog nervious and more likely to snap.
