Help, I am so worried about my girl.....:(

[GreyhoundGirl]

I'm really . None of my dogs have had this sort of things before. ( Phew ! ) It's an odd-ball. I'm pretty sure it IS smaller, though....

Does anyone else have any ideas as to what it might be?

The only way to know for sure is to have a vet examine it. Ask around, I'm sure you can find a vet who is more affordable than your current one. I would take her to the vet.
