Thin and cheap

Very thin, cheap and just not what I was expecting based on the great reviews and paid a little more too. Meh.

My high energy dogs favorite puzzle!
Bought this to keep my high energy dog busy. He has many puzzles but this one seems to be his favorite, a lot of them he wasn’t very interested in and would get bored and give up quickly. This will keep him entertained for about 10-15 minutes and is a fun thing for him to do as an apartment dog that needs enrichment in the middle of the day! Love how cute it is, especially during football season, we will give this to him while we watch a game so that he can enjoy the game with us lol

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.

Fair product
Color: Ohio State Buckeyes, Size: Standard
Product works great and looks nice. Stickers come up easily. Maybe not worth the price. But still is a good product.
