Your post is right on the money, AZPops. Where I live we constantly have coyotes and javalina roaming the area. The coyotes don’t bother the javalina, they’d get ripped up badly. But cats or small dogs roaming free likely won’t survive very long. Coyotes notice patterns and if they see someone letting a small dog out about the same time every day they’ll lie in wait and grab it. They’ve even taken dogs right off the leashes when the owner is walking them. Both my nephew and the lady living behind me lost their dogs to coyotes and there have been many other such instances. And you’re right; a 6’ fence is no impediment at all.
I recently ran across a guy walking his German Sheppard without a leash and mentioned the risk of coyotes to him. His attitude was my dog can take any coyote. I have an Airedale that was bred to hunt lion and I’m quite sure he could make short work of any coyote. But he’s always on a leash, if he took off after a coyote he’d likely to find himself dealing with a pack of them. Many people complain about why doesn’t the government clear them out. My attitude is they were here first, if you don’t like it, move yourself.
I often go well back in the boonies and a game ranger friend once told me if you see any coyotes, shoot them, they’re decimating the antelope herds. So for a long time I carried a 220 Swift with a 12X scope and never saw any. Then the one time I didn’t carry it I saw a pack of coyotes trying to separate the babies from an antelope herd and I was too far away to do anything about it. I temporarily forgot the boy scout motto, be prepared.
