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.

Excellent for boredom and learning

Wonderful! Daughters very intelligent Australian shepherd loves this. She takes it out when he's bored, or has t been able to give as much one on one. Well made

My little dog loves the puzzle toys. She doesn't really like the treats I got. I'll get better ones.

Keep my dogs occupied
Color: Grey
Great for the dogs. Challenging and makes them work at it but not so hard they can’t eventually figure it out.
