That is cuz he is also part German shepherd, he got the full GSD coloration going on but trust me if you saw him IRL you'd react just like I did when I first saw him.
That is not a dog.
the ears are another telltale sign notice how they have a concave profile.
I've just never seen a wolfdog where the dog colouring is so prominent, that's all, usually they have a more wolf-like coat (though I think all the wolf dogs I've seen have been huskies and malamutes, which have a somewhat similar coat colour already)
Yeah he is also quite old and that is probably why he's super chill also.
I normally am very against letting a wolfdog out in public or even people owning them without super specific qualifications but this one is a rescue and seems to be pretty tame. I even gave him a big ol' hug right before I took that picture because I've known them for a while.
That said he could literally rip me in half with relative ease and that alongside their wildness is why people should not just bring any wolfdog out in public.
