My GSD obeys me, but not my wife
I've had my GSD since he was a pup. He's 6 years old. He's reasonably well-behaved when I tell him to do things. My wife...not so much.
As a prime example, this morning my wife got up and let him out and he started barking at squirrels. She called him, went out on the deck and called him, etc. and he ignored her. I came out, called him, and he immediately came in.
I got him as a pup. We got married when he was 4, and I think it stems from that - I've always been the alpha dog, but she and the kids are just part of the pack I lead.
So what are some good techniques or training to do that would make him reevaluate my wife's position? He does listen to her a lot - if she tells him to lie down, stay, drop something, etc. Coming when he's outside barking is the major one.
