I wrote that on the 17th of June, today is the 23rd. All symptoms are caused from personality change after baby shot. Teets have softened back up, there is no fever, nose is wet, she is pooping and peeing normally. And no discharge from her vaginal area.
I have had a dog before that did the same thing after a baby shot, and didn't start eating normally until 2 weeks later.
She is eating when the mood suits her and drinking now.
I'd recommend bringing her to a vet as soon as possible! We can see hardened or even "full" mammary glands with a false pregnancy (sometimes even with milk), so this is not atypical.
That said, with a false pregnancy, your dog should still be eating and drinking normally. If she isn't eating normally, you should bring her to a vet right away. A uterine infection (called a pyometra) can be LIFE-THREATENING without surgery. I'd get her to a vet soon for a physical exam and possibly an x-ray!
Good luck and keep us posted!
