Needs improvement
Color: Green
The cups are deep enough and the bone has to have the circle to rotate before the bone can move. I had a hard time figuring it out and so has Our dog . There are 4 black rubber parts included but no instruction on what to do with them. After seeing the toy move across the floor, I figured out these needed to go on the bottom 4 corners. Cute, but needs improvement.

A fun interactive puzzle your dog will enjoy!
Color: Green
It's a fun interactive puzzle for your pet. I have a mini cockapoo and he mastered finding the treats on the first try. Then I made it more challenging for my dog and it took awhile for him to master it. My dog never got bored or gave in. He seemed to like the challenge of finding all his treats. Fun and challenging puzzle!

Perfect for keeping my dog busy and mentally stimulated
Color: Green
This has been such a great purchase for my dog. He gets bored easily and this keeps him entertained way longer than his other toys. I love that it challenges him mentally and makes him work for his treats,,it’s been great for slowing down his eating too. So worth it! The quality feels really solid and durable, and it doesn’t slide around too much while he’s using it. I also like that you can adjust the difficulty a bit so it doesn’t get too easy. It’s been especially helpful on days when I’m busy or can’t give him as much attention. Definitely recommend for anyone with an active or curious dog. it’s way more engaging than regular toys.

Your pup will have so much fun with this treat puzzle
Color: Green
My Westie, Maisie just turned four. I bought her this awesome treat puzzle for her. I was apprehensive whether she would play with it or not. She absolutely loved it. Took about five seconds for her to get over there and figure it out. It’s very well made and sturdy. The puzzle pieces move easily and so many combinations. She had so much fun looking for treats. It sits very flat on the floor and stays in place easily. Each section has a room for a couple treats depending on the size. They were very safe conscious when they know this product. No small pieces, but the animal are even a sad child to choke on him.She had so much fun. I highly recommend this product. You won’t go wrong. Great price.
