I've told here about the Arctic(?) fox that came up to the door of a radar station in Newfoundland. I threw him food a few times, but never tried to feed him from my hand, as some airmen did. I don't think any of us got bitten, but it didn't seem a good idea to let him get too close.
A few years ago, I was protecting a wealthy widow who'd received death threats. She lived in a splendid neighborhood where a stream flowed behind her home and there were acres of woods. This is smack in north Dallas, off of a busy street.
I saw quite a variety of wildlife, including big herons stalking fish in the stream. But the grey foxes were probably the most interesting. I sometimes encountered them while walking the property. I once was within 15 feet of a vixen and her kits on a driveway. I pretended not to notice them and after a pause, she led the little ones past me. No violence on either side.
But one big male fox was very territorial or something. This varlet snarled if he saw me and once perched himself on a column in front of the main house and "demonstrated" as the colonial British termed the ragings of a tiger.
He once almost came for me after snarling a bit. I drew my .357 ( S&W Model 66-3, Pachmayr Presentation grips; Federal Hydra-Shok.357 ammo with 158 grain bullets) but he finally stalked past, snapping at me from maybe 12 feet.
I called the zoo and talked with the Curator of Mammals and we agreed that he was probably being territorial, not rabid. But I was glad when I saw the last of him. Maybe a neighbor shot him. Or the man who worked on my night off...And there was a really big Great Horned Owl that might have been harmful to his health. He was a nasty beast, and I was glad that I didn't have to shoot him, as it might cause a problem with the police or some wild animal law or group.
I was recently told that a coyote was seen a few blocks from my home. I believe it. I saw one once along Lover's Ln. in north Dallas, just past the city limits of Highland Park. It was loping though a parking lot about 4:30 AM.
