It is called a prolapsed uterus. It is very painful and deadly if left untreated. My dogs mother had a prolapsed uterus and had to be rushed in for emergency surgery. And this was a show dog with a show breeder who knew what she was doing .
Go vet NOW. It can't even wait until morning.
Sigh. This is why we don't breed mutts and we study under a mentor for two years before doing any kind of breeding at all.
Your ***** is dying. Get her to the vet. A prolapsed uterus won't heal on it's own.
Here's a suggestion ..
Find an emergency vet number, get off the damn internet, pick up your damn phone and call the emergency vet and take your poor dog there!
CALL AF ** KING VET!
They have these wonderful things called, "Emergency Numbers"
duh, you take her to a vet before she dies of infection. Prolapsed uterus is painful and needs vet care ASAP!
My god you are one stupid mother * *****
GET IT TO THE VET NOW !!!!!!!!!!!!!!!!!!!!!!!!!!!
