I have a question my dog have a red ball in her rectal she born is 2010 and I check her and wen I touch it ..pop out wit blood and a little yellow stuff today the red ball is down..I want to know if that is danger and she could die.

I would call your Vet on Monday if it gets bad go to emergency vets

Could be a prolapsed rectum. This can happen from straining and a few other things. Needs a vet asap.

I would call your vet on monday and take her in but just watch it and make sure it don't get infected
