my pygmy doe has a round lump on the right side of her throat. she had a sore ( vets had no idea what it was possible puncture wound from fence it something) that healed up perfectly and it has been gone for a while now suddenly this huge lump had shown up. it almost feels like a tumor would when you palpate and feel around it. the Vet is coming out soon (this week) for shots and general checks but are there any ideas of what this is before I am charged a fortune for a bunch of unneeded tests. any suggestions or thoughts are helpful.
