When puppies leave their mom and littermate, it is extremely stressful. We want them to learn to trust you right from the start. So loving on them and shaping their temperament must come first. Often people jump right into trying to train obedience. The puppy can quickly get the impression of “frustration” from you if you first try to teach them new commands such as sit, or lay down, that they might not understand. So no matter what the relationship is always first!!
