Great toy for dogs or cats
Color: Clemson Tigers, Size: Large, Color: Clemson Tigers, Size: Large
Both my dog and cat love this treat finding toy. Dog (husky) can work it very quickly- the doors slide a bit too easily for him but the cat also successfully hunts up his treats as well. The quality seems nice and despite their use, still looks brand new.

Quality
Color: Missouri Tigers, Size: Large
So i got this for my dog who was board and distroying the house and or having anxiety attacks. This was a cheap option and he loved it as a beginner puzzle. The covers slide so easily and don't stick like wooden puzzles. The amount of treat pockets is also great. The dog doesn't care what team it is related to and neither do I. If you are looking to keep your too smart dog entertained, tis is for you.

My dog loves this toy

I've tried other engagement toys for my dogs but they didn't seem interesting to her. But my mini-Schnauzer loves this toy. She is excited when this toys comes out of the cabinet. It keeps her mind engaged. Easy to clean. Great value for the money.
