Hi
Our dog has a odd fatty type of lump on her chest/breastbone area. The vet said it may harden at some point and need to be removed then.
{not comparing you with my dog at all - but she is cute - too}

How many docs have you seen about those lumps?

If they can't find anything - maybe a very good naturopath/homeopath?
they can help to balance the natural chemistry of the body.
trekker- i had to laugh when i read your mention of the hairs problem - my hubby teases me about shaving them { but I just pluck em so far!}
