To the OP: If it was a rescue, it's likely just a stupid story told by a stupid person dumping their dog. Most rescues wouldn't touch a hybrid with a 10ft pole. Enjoy your dog!
Sunflowers, I have no idea what the point of your post was, or the point of the link. I know exactly what that "dog" (Sasha) was (she was around 75% Timberwolf). I know where she came from. I knew her for years. Her sire was a Timberwolf and her dam was GSD, Malamute, and Timberwolf. I don't need internet DNA on "dog" that was acquired out of state via road trip, proper permits in hand. My friend also has a USDA license for his farm and has a breeding pair of wolves, acquired when someone's zoo was shut down for inhumane conditions and he was called in to rescue them.
