The Buster cube came top in a recent trial of this type of behavioural toy.
Easy to clean, easy to use and keeps dogs amused for ages - especially the gutsy ones!
Dogs really work hard to get the treats you put in! Put some small dog biscuits or a dried cat biscuits etc inside and watch Rover go round the garden!
Try visiting the Buster Cub website (below) for info on how to use the cube.
