I hear ya Mike! These dogs from the wild are inquisitive and learn fast, much like German shepards.
He's going to be a great dog. Looks like he will need to know who's boss. That look tells me he will be testing you all of the time.
One other thing. Sometimes these dogs go through what is the land shark phase.
They want to bite everything. I use a squirter bottle. When they come at you with their mouth open for a taste of finger squirt him in the face and say no.
It took only 3 squires and Rupert stopped the biting. He still likes to have my hand in his mouth but he doesn't crank down hard anymore.
Also socialize him. Take the dog with you whenever you can. Get him used to different things,strange people,kids,other dogs,(very important) strange places. A confident dog is a good dog. A scared dog is a biter.
You will also find that he will bond with his trainer the most. But everyone in the house needs to take part in the training or he will only listen to the one person who does the training. He needs to know that he is at the bottom of the pecking order.
He looks like he has confidence and is a happy boy. I'm sure he's going to be a great dog.
