OH yes, the downside can be very problematic - if there are 4 people in the family, and the dog only listens to one person ... not ideal.
Can you have a family meeting to stress the importance of EVERYONE being involved? Have a list ready for the dangers that could happen to the dog if they don't have control (getting outside, not coming when called, etc.)
Sometimes non-dog people think we over react ... but if you have some facts to back up your rationalizations, it MIGHT help!
OR ... you could just put a really nice roast beef in the middle of the dining room table, leave the room, have everyone sit down at the table, and watch the dog eat their meal!!! that might help!
