Here in NV we're starting to see what we call "wolf coyotes"--they look like wolves and are much more aggressive than their smaller shy cousins. My father-in-law has been seeing them on his property and stays well away.
Biggest one I ever saw was at Area 12 at the NTS. They’d hang out near the dumpsters at Yucca Mtn. too... usually once a year some idiot would get bit trying to feed them.
Last winter I was walking my female Dobie here in Palm Desert Ca about daylight when one started circling us. He had his eye on her but she just stood still and rotated as he circled. She was on a leash and her hackles were up. I had a bead between his eyes with my little .380 but knew if I pulled the trigger the cops would be there quickly. He finally slinked/slunk? away. He wasn’t very big but acted hungry.
They keep the cats thinned out here in my neighborhood. They usually leave the intestines and some times the head. They take the rest to their babies (after they wean them from milk).
