They are almost certainly wolves IMO. I look at several things and in this video they all add up to say wolves.
1. Look at the length of the legs relative to the height of the body from the bottom of the belly to the top of the shoulder. Wolves have much longer legs than coyotes and in most cases their leg length will appear to be 2x the distance or more from the top of the shoulder to the bottom. On a coyote, it appears to be a little more than 1x this distance.
2. Look at the mass of the head and the thickness of the skull and the snout. Coyotes have more of a pointed nose and a thinner skull when measured across the top by the ears.
With these 2 things in mind, I believe these are wolves. As has been mentioned they could well be young ones, but I think you’ve got wolves here.
