Yes exactly!
We took her in because we were so worried about this lump on her head. We thought it was a scab at first...but then it started getting bigger and it had been 2 weeks and it still hadn't gone away. A friend of mine had just had her Snorkie in for surgery to remove a tumor. So I was particularly afraid that she had some kind of growth on her head.
Anyway the vet said it was just a scab and that she just kept re-bumping the spot and that is why it was getting bigger and not going away. But the insurance wouldn't cover it becuase there was no treatment needed.
ps. if anybody knows where I can get a crash-helmet in her size...let me know because she is always banging into something or other.
