Great for busy pups and smart dogs!
This keeps my puppy blue heeler busy and happy. Easy to fill and wash. I put her puppy food in it and put it in her crate to play with. The kibble fits perfectly in each little hiding place. After a month of fun it has not broken or malfunctioned.

Great treat
Gave this to my friend’s dog, and they took a video when they put it down! The dog immediately found one of the treats and kept looking for the other treat and eventually found it this dog loved it!

Easy, fun puzzle
My dog really enjoys this puzzle. It is a pretty easy puzzle for her. The only issue is that the tiles on one side does not slide easily like the other side. The first one I received was so hard to move, that I returned it for a replacement. The second one is better but still has the same issue. Other than that, it is made well. The size of the puzzle works well for my 5 lb dog.

Fun toy for puppy
My 2 (currently 3) month old puppy was able to figure out this puzzle quickly. It did keep him busy which was great, and he really liked it.
