How weird to come back on and see one of the new puppy owners on the forum. Welcome.
Yes I am the breeder and the reason I am able to let them go at 6 weeks is that the mommy is doing a great job of weaning them herself and they are doing well at eating solid foods. They are all getting socialization each day and are quite secure and developing their independence.
My vet says that she lets her puppies go, that she breeds, at 5 weeks, but I did feel that was too early. For one I want them all to have their first shots before they leave and that is going to happen at 6 weeks of age exactly.
So now about Diesel. He is doing very well. He is getting so big. I've attached a couple of pictures to show how big he is getting.
He is my husband's favorite as my husband is a truck driver. He loves this sound that Diesel makes that he says sounds like a jake brake. He's really developing a cute personality. Not too timid, not too overpowering, just very playful and he loves to investigate new things.
