Hello Mommybear,
My 12 year old Lab/Chow mix has lumps too. The vet told us they are like a blood cyst. They feel lumpy and squishy at first and they get harder as they shrink, but may never totally disappear. The vet said it could have started out as a bug bite.
We didn't even notice them until we had her shaved down at the groomers. They notified us of the lumps. She's just fine...still has them but they are hard and much smaller now.
Good luck. Hope its as simple as our JoJo's was.
