Hi all! I found a hard lump (size of a marble) on Rocky's (Corgi/Lab mix) front leg, near his wrist. I called my animal clinic, but the vet I usually see doesn't have an appointment til the 24th. I looked on google about the lump and kept getting results for bone cancer (ugh!).  I'm so worried, I don't think I can wait 11 days to see his usual vet. Has anyone else had a similar issue with this? A hard lump on their dog's leg? Thanks for any input!
