Honey, I just saw this thread. I'm glad Freddie is doing OK.
Josie, my lab, is a lumpy, bumpy beast. I call her Lumpy Squeezemeyer!! Don't ask, just another stupid name I made up for her.
We found a lump on her neck on Thanksgiving, which terrified me. I took her to th vet and they said they were 99% sure that it was a fatty tumor, also called a lipoma. She's got about 10 of them. Anyway, better safe than sorry, I had it aspirated and it was in fact a lipoma.
Labs get them more than any other dog.
Hugs and kisses to you and Freddie.
