I’ve got to get in some target practice. The other night, there were a couple of coyotes moving along the river bank
down below us - an adult and a little one. So far, the coyotes out here have stayed wild and timid; but there are so many dogs in the area that have gone feral. If they ever start mixing with the coyotes; the bloodline will become bold pretty quick. - We used to keep the dog feeder in the garage; until one day I saw Wiley Coyote come streaking out the garage door. - I used to walk alone down on the river bottom below us; but now not so much. We got a nosy neighbor across the hill from us who liked to lurk on the property line and engage me in a conversation every time I tried to walk through our woods. He seemed to be retired.
Any canine will do that, from the neighbors' dog who 'goes' on your lawn, to coyotes and wolves. It is part of their psyche.
With coyotes, you just need to assert dominance over the terrain. That covers the gamut from cowboys relieving themselves along fence lines to the occasional shot coyote. Not being present, not taking the occasional potshot at one will guarantee they grow increasingly bold.
If your dog is a male, take it for walks around the perimeter of the property. It will mark territory to the point of being annoying (frequent stops), especially where another male canine has left a mark. That will at least let the coyotes know they are not alone.
It also gives you an opportunity to check for tracks, both coyote and others, just to see what sort of critters have taken up housekeeping in the neighborhood.
