They think I'm part wolf?

So mom e-mailed this lady contact of hers about me, and sent her a link to a photoalbum of me.The lady believes that I am mid to low content wolf though I also could just be a very wolflike shepherd mix. Mom says I act like a wolf. I mouth and howl a lot, though malamutes howl a lot too. She also says if I have shepherd in me she doesn't think I have a whole lot because  I rarely bark and every shepherd she ever met barks A LOT. Even when I do bark she says it doesn't sound normal, too airy. I guess there is no way to tell for sure right now so we will just have to wait. They have DNA tests for dog breeds, do they have them for different types of wolves. We could do the dog breed dna anyways just to see if I'm missing a chuck of percentage in breeds. Like say for example 50% malamute, 25% german shepherd, and 25% unknown. When you take your dog in for these they can do just about every breed, and they at least get all the breeds of dogs that live here that I could be. So if there is an unknown percentage it is probably wolf.
