Hey guys...thanks for your thoughts and prayers!
We just got back from the Vet. He confirmed my thoughts that it is indeed a small hernia. He seems to think I should just watch it for a little while before deciding if I would like to have surgery on it. I do have to say she is acting fine now. He was able to push on it and it did not seem to irritate her. The only concern I have is she is such an active dog - she LOVES to jump and leap over thing, thus why I am enrolling her in an agility course coming this summer.
I hope it will not affect the way she likes to do these things.
I guess I will just listen to the Doctor and keep an eye on her for now. If this seems to irritate her a few times more I may have to go ahead and get the surgery done on her. Thanks again everyone for thinking of little Mia!!
