I have a8 week old American bully puppy.. completely independent of their mother for natural nutrition. I love them, they are so smart, they fetch the ball, rope already, I am litter box training them, so far so good. You just have to be patient, I put them in the litter box after they eat and before and after play. If I can't supervise them they are in a crate. We also have a 17-month-old boy and they are so good together, they also love to play with children and other dogs and cats
