This is (mostly) Dakota from the Wild Spirit Wolf Sanctuary in western New Mexico.
He loves people, and he especially loves beards... that's why he attacks John so much. xD He greets people by jumping on them and licking their face... this is why the camera goes crazy in the beginning. I'm only 5 feet tall, so he was definitely bigger than me, and he knocked my glasses off. xD
***EDIT: Several people have informed me that Dakota and his siblings here are high content wolf dogs. I honestly thought they were 100% wolves, because that's what the guide at the sanctuary told me, and it's also what their website says. But then others have told me that those several people are wrong, and that they really ARE 100% wolf. So, I dunno what the truth is. :B
