Bests & Worsts Reviews from Amazon

I like the idea of a dog puzzle and bought both different puzzles that were offered.My dog has done other puzzles before and loves games. Unfortunately, these were not made by someone who loved or even cared about dogs. They are just press-board; a step up from cardboard, and glued together with formaldehyde. It says this on the label. My dog got all but one treat out and just sat smelling the last treat inside, the moment I turned my back, my beagle attacked the press-board with her teeth, imagine that a dog chewing a toy to get a treat.... the press-board gave way immediately and my dog got the treat. She also got a dose of formaldehyde.... The trouble with society is typified by this dog toy: it is not in the least bit chew-able and any dog toy with food inside is going to get chewed. The second problem is poisoning a dog with the formaldehyde. Buyer beware. I wish someone told me it had these features.
