Anyway, vet did a biopsy-- he just called us. Fatty lipoma! Not doggie breast cancer. Nothing to worry about. Oh, you guys, I am so relieved! It is just a little bit of extra dog. I suppose we could get it removed, sometime later, but no need now. You cannot even really see it, you will only find it by petting her undercarriage.
Son and I went right in to where she was sleeping, and told her how good she was and hugged her. This is her deep sleep time, she looked at us in astonished outrage, and went right back to dog-snoring sleep.
So, the color has flooded back into the world. Now I can think.
