What could this be on the Does jaw ? (been watching for 2-3 years and never had a shot at her) DoeChew4 - YouTube
Either arterial worms or a swollen jaw from bacterial infection more than likely. The nematode worms are caused by horse fly bites. The bacterial infection is from a bacteria already normally in their mouth but if a thorn or something causes a sore in their mouth it can cause an infection from that bacteria.
Shot a doe like that 7 years ago in Arkansas. It was an infection from a bad tooth. Burned her on a brush pile.
Your call, it's not transmissible between deer...deer to deer nor deer to human. Supposedly doesn't hurt the meat but I consider it a bad idea to eat an animal with an obvious problem. I have a 168" buck with a 7.5" right drop tine that had a healed jaw knot so it's not necessarily terminal and I ate him but he appeared healthy when taken and the knot was barely noticeable unless you looked close. She'll probably be okay, I wouldn't put her down out of fear of it being something that spreads deer to deer but that's just me.
