You don't need to be intelligent to train dogs, the family we got our dog from were lovely and everything, but very dim. Breeders by name and nature, they had about 6 kids and 10 dogs. But I have to agree with Lep here, getting your mum a present that she won't actually like is pretty low. Remember the episode of the Simpsons where Homer got Marge a bowling ball with 'Homer' written on it?
