My parents Rottie, Athena, chases her nub around. It is quite hysterical albeit a little sad because you can tell she thinks she should have more tail. When they had a mixed breed Rott/Lab/Chow companion with a large plume of tail Athena was in awe of it. She would chase the tail and grab it like she was going to steal his tail. My Schnauzers wiggle their stumps with such enthusiam I am glad they don't have a full tail, plus natural Schnauzer tails are like little whips!

MP-Hope your little guy doesn't need an amputation!
