Please do not feel bad and think you have to go to another forum. The people on here are supportive and kind. We all have our pet peeves but that is part of being human. We truely want what is best for the dogs.
In my research I have found that there is a great deal of debate of the best age for a puppy to go home. As a breeder you have more work to do, so to speak, once they wean from Mommy. However if you are breeding for the right reasons then you treasure that time as much as the beginning.
The litter mates and mommy teach each puppy a lot during those last 4 weeks. Now you will have to step up and do that teaching.
It really sounds like you are trying to be a great mom. Just relax, follow your heart and research on here. There are some suggestion threads from other members post on how to teach them what they would have learned those last 4 weeks. Dont forget to be patient with him too.
Best wishes and remember we LOVE pictures on here so please show off your little one when you get him.
