I have an 8 yr old Dexter cow that seems to have fallen through the dirt covering an old well on my new place. Hole was about 3' in diameter and about 2-3' deep. Can see the tracks were she walked across it. I now notice she has what looks to be a hernia. Does not seem affected by it at all though. Is it possible this will correct itself? Is this something that I should watch or get her to the vet right away? Thank you for any help you can give me.
