Santa brought a winner. I can't believe how much they love these. Truthfully Santa (my mother in law) gave them one. No way would alpha dog Lady share so I got two more in the puppy size. Now each has their own and they are all wild over their Kongs. I have been on this board for well over a year, heard of Kongs but never got one. For anyone out there looking for something to keep them busy, if you don't have a Kong, get one!
