I agree, the further inland and north you get the bigger the Grey Wolves get, and they can be a mix of all colours, grey, brown, black, and other woodsy colours that help them blend into the forest environment. They used to be colloquially called Timber Wolves when I was growing up and they easily could bring down large wild animals as well as large livestock that weren't properly protected. The white Arctic Wolves are somewhat smaller and more timid because of the types of foods they have available to them either by hunting or stealing.
And those Sea Wolves on the coast, although they are mainly seafood eaters, are also known from time to time to go island hopping on raids for deer or whatever else they know is on the islands. They will go to small villages or sports fishing encampments or lodges on the islands to steal small livestock that are running loose, but they seem to be particularly keen on stealing and eating dogs.
There have been recorded videos of them shown on the news of small packs of Sea Wolves dashing into villages and encampments to create a disturbance and distraction while a few others will be in the background snatching up dogs or puppies, cats, chickens, snapping their necks then running off into the woods with them. Once they've caught what they could the rest of the distraction pack would disappear into the woods too. They're really smart animals. Just because people with animals might be on islands doesn't always mean that their livestock or pets are safe from predators. Not when there might be sea raiders watching them, even if it's just a solitary lone wolf raider.
But I confess, I really like those wolves, I think they're the wolf of the future that will be more readily able to adapt to the climate changes that are striking the north now and getting increasingly worse with each year that passes.
I feel that if people are going to own livestock it is their responsibility to protect their livestock and ensure their safety.
