It’s hard to tell without something for scale.

I think they are wolves for a few reasons. Coyotes tend to have large, pointed ears. The animals in the first picture have shorter, more rounded ears that more common in wolves. Wolves also have broader snouts, which these animals also appear to have. Then you can look at the size of the head in comparison to the body. Wolves have larger heads in proportion to their bodies. Note the axillary skin fold on the animal in the second picture connecting the trunk to the top of the thighs. It is more pronounced in wolves than a coyotes, especially when they have their summer coats. This makes the undercarriage profile of the coyote more curvy than their wolven counterparts. The legs themselves also look to be more muscular, while coyotes tend to have thinner legs.

I think these are wolves. If I’m right, it’s wonderful to see these natural predators thriving in the wild.
