By the way, there's an excellent book called The Dog Listener, by Jan Fennell, who used to do programmes about problem dogs on Channel 4 or UTV, forget which. Well worth a read. And she has a new book coming out.

If you're rich and in England, she does sessions - I was going to say dog training, but they're more owner-training - for £250. Dear, and impossible with the price of the euro, but you might find it worth it.
