Mattie, its a long shot but here goes, my little pup had lumps all over his body but they started with just 1 on his side. His eyes got runny,then his ears, then the lumps started everywhere else, it was called sterile Idiopathic Nodular Panniculitis. From what I know it can start anywhere, also it generally caused by infection/bacteria. A biopsy is needed to determine the diagnosis tho. Vit E was prescribed as well as high dose steroids. He had steroids at first but it was only when the dose was highered it got under control, I remeber that bit well.

ps symptoms are very very similar to an allergy....in a way it was cos it was a reaction to his vaccine.
