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.

Happy hound!
Color: Yellow, Color: Yellow
My 2 yr old bloodhound destroys every toy in minutes, but not this one. My husband and I actually buy toys to see how long they last for fun. Although the croc is NOT indestructible, it lasts a whole lot longer than most. After an hr or so, I took away the only piece he's chewed off which is part of the back leg. Otherwise nothing else is missing off the croc. Our boy has been very occupied with this new toy and we're satisfied with his new distraction!

Definitely a tough toy
Color: Blue
This is one of the few toys my Boxer/american bulldog mix hasn’t been able to tear apart. He loves chewing on it and I love that he doesn’t chew on stuff he shouldn’t. I have such an issue with toys being torn apart the day I bring them home. I wish there was a safe way for it to have a squeaker since he loves squeakers but I don’t think that is possible.
