That is hilarious what your pup does, LOL
Schatzie doesn't do the dance but she seems to wait till the last moment when she can't hold it any longer than makes a mad dash to the potty pad. Being in a rush she seems to walk away off the pad prior to her finishing so at times she leaves little treasures behind her, then looks back and has the expression of "did I do that"
If she could just take sometime and slow down once in a while, ha hahaa
