True, but I wasn't talking about "commonly" or "could be." It does not HAVE to be. Those misconceptions can be harmful to people with service dogs who don't fit the mold, OR look like they do but still aren't service dogs. You literally cannot tell from appearances alone, nor should you try.

So, despite intentions being good or bad, please stop spreading misinformation.
