Which main character was a veterinarian before the apocalypse?

Hershel Greene was a veterinarian before the apocalypse in The Walking Dead. He later returned to his family farm in Georgia, where he raised Maggie and Beth and cared for livestock.

Hershel first becomes important when he treats Carl Grimes after Carl is shot. His medical knowledge, religious convictions, and belief that the walkers might be curable initially put him at odds with Rick’s group. He eventually accepts the reality of the outbreak and becomes one of the survivors’ moral leaders.

A common mix-up is assuming Hershel was only a farmer. In the television series, he is specifically described as having worked as a veterinarian before settling back on the farm. Maggie, Carol, and Dale were never established as veterinarians. The comic version also presents Hershel as a farmer with veterinary experience, although his family history and role differ substantially from the television adaptation.
