Thank you all.
You know, Donna may be on to something. I did take them in on the 19th for shots. I can't remember exactly where the shots where given though. She got her rabies and distemper shots. Then the nasal bordetella.
Well, I hope it is nothing to worry about because I can't take her to the vet until next week. I get paid this Friday and Bruce is expecting to get paid next week as well. So for this week I will just keep checking it and if it seems to grow larger rapidly I will definitely get her in ASAP.
It doesn't cause her any discomfort even when we poke around at it. So that helps me not worry as much too.

Thanks again everyone. I knew I could count on my PT family to help me calm down.
