Ok, So Lilly gets this pimple on her from leg about two weeks ago, I thought maybe a bug bite. and as a bad mommy didn't pay a lot of attention to it. On Monday I notice it has about doubled, if not tripled in size. I took her to the vet yesterday and they took a sample and gave me antibotics and a creme. I told them to hold off on sending the sample to the lab, (it was expensive and couldn't guarantee anything) as I was hoping that the medication would help and all would be good.. Here is a picture of it. Has anyone ad anything that looks like this?? If you did what did it turn out to be? What did the vet do for him or her?
