What if they wag it in both ways? Since ABBY has a nubby, sometimes it's hard to tail. Oh, I meant 'tell'.

I have to say, I've noticed Cuddles wags predominantly to the right. I thought it was a neurological disorder until I read this!

Interesting..... Chief's nubbin goes to fast for me to see which direction it's going in
