...My horse has a lump in her neck.. The upper part under her Jawbone. Looks like a swollen gland. I noticed it about three weeks ago and have been watching it to see if it changes. It hasnt gotten bigger and hasnt caused her pain. Its not hard and not mushy but is soft to the touch. I guess I should call the vet in the morning. Does anyone have a clue to what it could be? Shes UTD on everything, even strangles vac.
