Thanks for your replies, they are very helpful. I'm just frustrated b/c there really is nothing to do. All of Lady's bloodwork came back normal and I was told that I just have to watch and wait. Then unfortunately, I'm related to non-dog lovers who don't get why I'm concerned. Luckily she is back to her normal crazy self. Barking at anyone who comes within 3 feet of me as if she could do anything except attack an ankle or two and wrestling with Neo, her baby Yorkie brother.
