Having purchased the smaller version with success, I decided to buy the larger toy as it would hold more treats. It does but unfortunately, unlike the smaller toy, the rope is too short and is impossible to separate the cups sufficiently for our very intelligent Welsh Springer Spaniel to access the goodies. Needless to say, she has become bored and the toy is now a complete waste of money.
My Labrador loved this toy but he found there was not much room for manoeuvring the coloured plastic bits, so he very patiently undid one of the knots with his teeth and slid them off ... genius!!! It certainly gave him and us some entertainment.
