Day three and Wilf is still infatuated with his latest toy. In fact our morning walks are cut short so that he can rush back home to sit on the lawn and play with it. The object of this attention ? A hard plastic ball that makes different animal sounds whenever it's touched . According to the packaging it's a ' virtual zoo that interacts with your pet '. The thing is supposed to make more than 20 noises but Wilf responds best to the lions roar, the puppy bark, and the monkeys screech . He sits there with this electronic menagerie between his paws, head back, tail wagging, emitting his best high pitched play bark and acting like a six month old . It's wonderful to see him pushing it backwards and forwards as it talks back to him in its myriad of voices . The ultimate toy for a game of hide and seek with a blind dog. To stop him chewing the thing to bits ' the font ' has now put the ball in an old pair of my rugby socks . " That way he'll be able to find it whenever he wants " . Swedish humour at its best .
