    Great!
    Color: Pink, Color: Pink
    Perfect for my small poodle mixes (13 lbs and 18 lbs). My dog (the one pictured) was able to solve this fairly quickly, but nonetheless it is amazing that she’s still taking the time to sniff and eat slowly. What I like is that even when she’s done, she goes back and re-sniffs and double checks in case she missed anything. It seems good quality so far and it’s been very easy to both set up and wash! Would definitely purchase again and would definitely recommend!

    Stimulating for Dogs
    Color: Pink
    I use this for my blind and deaf dog. I crumble up small bits of treats and snacks in each compartment for her. I thought this would keep her busy for a while, but she figured it out quickly. The compartments are easy to load, but you need to break up the food or treats into small pieces. If the pieces are too large, they shift during loading and jam the slides. When the slides get jammed, it is hard for my dog to move them around and get to each compartment. She then starts chewing on the slides to get them to move. So far, she hasn't damaged the slides. The ones in the middle spin in a circle, so once she learned that, she breezes through those. She uses her nose to spin them in one direction to get to each compartment. The ones on the outside can be loaded on either side. She learned she has to push or pull those with her nose. It isn't much of a challenge for her, but she loves discovering the treats inside each section. The back has rubber feet, which keep it from sliding too much on the floor. It is well-made and durable. I hand-wash it. It is easy to clean out each section. It is exactly what I was looking for, and the pricing is excellent! I only wish she weren't so good at it and it kept her busy longer.

    Great size for puppy size vs big dogs
    Color: Pink
    Dog's a nuisance, but fun. -5min after eating poops. This game wasn't a lot of food, but same result. I won't bore you w/a 2min video. But this was so much fun. Others I saw were bigger looking & this breed needs everything bigger. But for now it was the perfect distraction.. & it helps in training him to use his senses

    Nice item, good for small dogs/puppies
    Color: Pink
    Fun toy, easy to inbox, all the pieces were there, nothing missing. Kept my Dachshund girl busy hunting treats. The size makes me think it’s good for smaller dogs or puppies, this is not a large item. Would buy again, would recommend
