All of my vet test came back normal.  My blood work is just fine.  No thyroid problems, and my bottom is just lumpy without anything cancerous.  I didn't want to get my butt examined, but I put on my big girl pants and did it.  If you need to do the same, go ahead and schedule your appointment.  If you are 50 or older, get a colonoscopy.
I have a goose egg on my bottom.  Only I'm small, so it's more of the size of a quail egg.  My LADY thought it was an anal gland problem, but it turns out that it's a tumor.  They took a sample, which was not fun-mind you, and now we are waiting to hear the results.  We are all hoping that it is just a fatty deposit.  Never before have I ever, ever hoped to just have a fat ass.  We also discussed my weight problem and they are running a thyroid test. We will let you know soon about my test results.
