I often wonder if this website causes problems with our dogs being seen as the dogs they are, and NOT hybrids (especially in the US, where people believe everything they read on Wikipedia):

Maybe it is hard for uneducated people to believe that our dogs are not considered hybrids when they google in "wolf hybrid", this link appears first, and the first image underneath the heading "wolf hybrid" is Jolly...
The site does go to explain the dog breeds that have used wolves near the end, but I think it could still be easy to make a mistake if you were not familiar with the CSV
