Hi everyone,  Our Bully Lily is a 12 year old spayed female in overall good health for her age. Yesterday I noticed a kidney bean sized protrusion of flesh or tissue coming from her vaginal area. It is still there this morning. My husband gently pushed the tissue back inside - but I think that's just a temporary "fix"

We will call the vet in the morning, but I wonder if anyone has had this happen and what the cause was and also options for treatment.  I've read that this happens with intact females in heat or after giving birth - but those are not the conditions here.  Because of her age I am worried thiat this is something like cancer. 

Any advice appreciated.
