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.

Too easy for my Lab
Color: Blue
My lab figured this out in 30 seconds. I was hoping it would be a bit more challenging for him. Thankfully, it is challenging enough for my bunny!
