My pup loves these, but we use them with the yellow forms for the round toy. We put puppy patte on the bottom then one of these in the middle and freeze it- then put it in the round toy with the dental toy sticking out of the middle- this makes it harder for them to finish and we only use 1 at a time instead of 2 each time with the dental toy. (And using 2 in the dental toy takes less time to finish)

At first it was a little challenging for my boy to figure this toy out. Once he got the hang of it, I could tell he really likes it. Its a win!

It actually cleaned my dogs teeth! He was starting to show some build up and majority of it is gone now
