I would save an animal depending on the situation. If it’s seriously hurt and there’s nothing I could do for it I would call an animal service of some kind, and I would sit with the animal so it wasn’t on it’s own. If it was stuck in like barbed wire or in a hole etc. I would try and get it out, doing it carefully to ensure he animal wasn’t in as much pain. That’s all I’ve got really, hope it helps though :)
