Any animal.
Try to fucking kill me.
Feral dogs have mixed in with coyote in the area, and there’s indication that the eastern coyote is mixed with wolf anyway.
But, it leads to small packs of canines that roam, usually with enough size per critter to be a problem even alone. They aren’t usually huge, but we’re talking anything from a little over knee height at the shoulder to a little under hip height. I’m 5’11". The ones that are more dog, and the actual dogs, tend to have a wider range of sizes than the coydogs. The coydogs, for all intents and purposes, are around coyote size, though they tend to have odd coloration and are a bit less lanky.
They’re usually not going to outright attack anyone, even if you’re alone, unless you’re alone and have your dog with you (which isn’t really alone, but you know what I mean). But I used to go out into the mountains by myself (after checking in with rangers).
A couple of times, I had some in the area I was hiking or camping with no issues. They are usually skittish. But twice over the years back then, conditions were bad for them, and I had food. The first of the two times, I scared them off. The second, I had to kill several, and may have stained an otherwise good pair of jeans by the end of it. Only had three rounds left in my second magazine too.
Didn’t return to that area unless I knew conditions had been very good.
Ran into a bear once too. Not as in literally running into, but we saw each other through the woods, close as I’d ever want to get. Ngl, I may have stained those pants a little too, but the mud I fell in hid that. Stumbling backwards away from a bear doesn’t let you see where you’re going lol. Startled the bear, and we both took off running.
