Norwich Terrier

With their ears bolt upright like Norwich Cathedral, these dogs are always alert and ready to play. Their ratting instinct means they love to chase any kind of toy- motorised mice toys are a particular favourite. Norwich Terriers are generally obedient, but they can be trickier to house train so specialised training tools may be necessary. Their habit of hunting means its best to keep them on a lead in unenclosed areas in case they go careering off. Celebrity owner: Joan Rivers.
