Just a big coyote. Though the easterns have been found to have some wolf DNA, it can vary from 25% and on down. The ones here would be in the lower # %wise, though some dog would also be in them. Hard to say without a genetic test of the actual animal. There are some that look more wolf-like along with their larger size. Here's some pics. My personal taken 1st coyote (Harford county), a NJ animal, and a Baltimore county roadkill. Mine was a pup at 26 pounds ( had big front feet, so he was going to get big had I not gotten him), the NJ one I have no idea of weight, but looks to be at least 45 pounds, the roadkill was 42 pounds. The roadkill has thicker than usual front legs and a wider snout. Last 2 pics are the beefy one mounted ( but not finished), showing the wider snout and head, which I had to make alterations of to the coyote form.
My Grandfather got a picture of a huge Coyote on his trail cam one night last year. If I find the picture of it I'll post it up. Right outside of Mount Airy.
Around my house in the same general area we've seen and heard them at night. Last year a friend shot a doe and we were tracking it. When we found it an hour later it had already been darn near half eaten (from the back end, not like somebody else gutted it and left the parts).
We've been seeing a lot less fawns in the area and it's starting to piss me off. No fawns=No decent deer in the coming years.
I never really wanted to shoot anything that looked like a dog, but these things may just feel my wrath
