Regarding wolfy looking dogs, my pup is a husky chow mix and is frequently mistaken as being a wolf mix to the point that the woman i got him from claimed his mother was part wolf. He's a wonderful dog and he's registered simply as a spitz mix, but I worry over the amount of people who insist he is a wolf dog (including my own mother) and how I could protect him from false claims?
I’d suggest getting an Embark test, since they’re the most accurate for identifying wolf content (plus, you get a ton of really interesting information on your dog’s genetics and the history of those genes). That way if there’s ever an issue you can immediately have a decently respected test to pull out. It might not protect you entirely, but it’ll be a buffer.
Also, y’know, just be super straightforward whenever anyone calls your pupper wolfy or talks about “wolfdogs” about why that’s wrong, and do everything you can to clarify misinformation so the people around you and your dog stop spreading it
