I agree. This pink 'ball' is not normal. She is unsuitable for breeding, and needs to see a vet quickly.
Yes, sounds like a prolapse and I hope you are not trying to breed her! Best to get her spay.
Sounds like a prolapsed uterus. Get her to the vet. Do not try to breed her.
A pink ball??? That is abnormal. Please take her to your vet. And please remember that unspayed females can have lots of unwanted puppies. - Blu
