Small world lp.....I actually know the person who invented this gadget!
My dh cousin's best friend. I've had one of the first one's for over a year now. Haven't used it much, 'cause our dogs each want one. Only takes a few minutes for Molly and Zoe to find all the treats. Not sure if she has marketed different sizes yet....i'll have to find out. Haven't tried it on any of the foster pups yet...figured they are too young. Maybe i'll try it out tomorrow and see how they manage. Would certainly slow them down mealtime for them.
I'll certainly pass on your comment to her.
