Agree with what's already posted. If you and your wife are actively engaged with caring for/training your dog, he is going to listen to you above all else.
Mine is just a pet/agility dog that I have worked with for a year now (got him when he was 8 weeks) and in my current apartment, even after having my roommate do some work with him to make sure he'll mind when I'm gone, Kaiju will still ignore my roommate if I'm asking him to do something different from what my roommate has asked. Just the other day, my roommate called him to come but I preferred him in the kennel and asked him to do that immediately after. Guess which one he did?
