Durable interactive fun for You and your Dog
Style: S-Level 2
It’s it’s an interactive toy if your dog isn’t lazy like my little boy. He likes to play, but he wants me to show him where everything is. It’s very doable because he’s rough and tough and it was much more reasonable than some of the other interactive toys..

Fun dog product
Style: S-Level 2
When I first got this, I loaded up the compartments and set it down for the dog – excited and interested to see what she would do. She looked at it smelled it walked away. Disappointed – after a few hours – I put it under a table where she has a little rug, she likes to lay on. The next day I could hear the little doors on the toy rattling and she got every single little treat. And she loves it. And it’s fun when she decides she wants a little snack that she doesn’t have to ask or beg for she goes to her little toy and takes one of the treats out of the holes. It surprises me she never tries to chew on it. And I haven’t figured out how to make it squeak yet, nor has the dog. But it’s something all for her and she loves it. And it cleans up easily too.

Great dog toy
Style: S-Level 2
I buy this on repeat for my dog. It was fun when he was just a puppy, learning. He loves it so much that I can now put treats or kibble in it, and since there are such positive associations with it, it's a great way to get him to eat.

Not for powerful breeds like Rottweilers to last long, otherwise yes!
Style: L-Level 4
My 7 month old Rottie just loses patience and tries to eat the buttons. My 9 year old Rottie figures it out in 5 minutes. This would be perfect for a less powerful dog but not sure it will keep them busy for longer than 10 minutes. Mental stimulation is very important so I’d still recommend
