My 4 year old, Chassis, has some type of hard lump on her front leg, about an inch above her paw. It doesn't seem to bother her any if you touch it or try to "move" it. My mom was thinking it is probably a cyst of sorts. She plans on taking her to the vet about her seems-to-be-excessive water drinking. Would a lump on her leg have anything to do with drinking a lot of water? (Symptoms of a same problem?) She said she would ask about the lump while there, but I was wondering if anyone else had a similar issue with their furbaby.
