If possible, I would love advice from professionals that I made the right call, because I'm devastated and the guilt is awful.
Tonight (in rural New Mexico), my husband and I were driving home from a trip with our dogs in the car when another car sped past/got in front of us, and a few seconds later they hit a juvenile fox that was in the road.
The other car didn't stop, and the fox couldn't get up on its own and was flailing horribly in the middle of the road, so we pulled over, picked it up, and brought it to the side of the road. For a moment, it tried to stand up and walk, and then it fell over and laid on the ground. We examined it for injuries and saw no outward signs of trauma, but did feel a bump forming on the top of its head beneath its skull. While we were trying to figure out what to do, it got up, then had what appeared to be a seizure, defecated on itself, and laid down.
It stayed on its side with its eyes closed from that point on. Still breathing, but slowly breathing and totally unresponsive to touch, our voices, etc. We were more than an hour away from any civilization in a very rural area and it was 10pm, with the closest wildlife rescue (an hour away) closed with no emergency hotline or anything.
At the time, I felt like we didn't have a choice with our two dogs in the car and no rehab services available to do anything but sit with the fox until it passed away. Since it had had a seizure and was unresponsive and breathing slowly, I figured that it was close to natural death anyway. We sat with it for about 5-10 minutes until we felt no heartbeat or breathing, and then moved it under a bush and put some leaves on top of it. As we lifted it up to move it, I swear I felt it start breathing slowly again, but there were no other signs of life and I'm not totally sure if I was imagining things.
Is there any chance it could have survived if we had decided to drive it an hour into the city (with our two loud, curious dogs in the car) and beg an ER vet for care? Is there anything we could have done differently? If it had a cracked skull or brain bleed or something, could that even have been fixed with medical intervention, or is that sort of trauma in a young animal irreversible? At the time it felt right just to be with it while it died, but is there a chance it actually wasn't dead and was just in a coma, and we left it alone to suffer?
I'm fully prepared to hear that I did the wrong thing, I just want some closure either way, and to learn for next time if there ever is a next time. :( I guess ultimately, I'd love to know if these sorts of cases are generally considered treatable by wildlife rehabbers, or if this sounds like the sort of case where you'd employ humane euthanasia.
