I received my interaction toy two days ago. I have two dogs, a small chihuahua and a medium sized Jack Russell. They both love it and it keeps their attention for long periods of time. I decided rather than leaving it out, I put it away. So when I bring it out they get excited. I used healthy liver treats and they worked well. Your dogs will love it too. It makes them think. They can smell the food, so they have to figure out where it is. Also my toy arrived fast, nicely packed and in good shape.
My dog find it very nice so to eat. The printing snapt he haven't. But the puzzling he finds fun.
