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

Color: Iowa Hawkeyes, Size: Standard

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.
