Five minutes of entertainment
Color: Grey
My eight pound chihuahua mix figured the puzzle out very quickly. It kept her entertained for about five minutes.

Small in size
Color: Grey
Very small, picture makes it look much larger than it is. Seemed more appropriate for a cat, and 6 month puppy figured it out in under 1 min. Not very challenging.

Durable and engaging!!!
Color: Blue Green Orange
This has been a game changer! My dog all of a sudden started gently chewing on a couple of my shoes while I was at work. I set this out right before I leave for work. My shoes have been safe ever since!!!
