We’ve worried about the fella with the two wounds which was posted a couple of weeks ago. The wound on its haunches grew larger and redder over the next few days, maybe due to its becoming infected. Intervention is always a bad idea unless it is absolutely necessary. Trapping a coyote is extremely traumatic and harmful to these wild creatures. If antibiotics were to be offered, say, hidden in food, there is no guarantee that the right animal would get them.
I recently spoke to a medical doctor about it. The coyote has been biting and licking it, which I thought was making the condition worse. In fact, it turns out that licking is the best that can happen. Animal saliva contains some antibiotic properties, so this self-medication is the best proactive measure — and it’s being done by the animal himself!

It is also interesting to see from your pictures that coyotes ‘shave’ the area. Charles
