After my dog gave birth, a large flesh ball prolapsed from its anus.

A dog prolapsing a flesh ball from the anus after birth is rare, because the birth canal and anus are different; some mothers prolapse the vagina or uterus from straining. If it clearly comes from the anus and the dog has diarrhea, it is likely rectal prolapse. Prolapse needs prompt diagnosis and veterinary reduction without delay, or the tissue may infect and necrose, making recovery harder..
