I am going to be choosing a puppy from a reputable breeder. They have two litters currently that have the same approximate go-home date and will be similar in size. My question is - how much does the parents' temperament play into the puppies temperament and personality? One litter - dad is more eager to please, cuddly and mom is friendly and sociable and likes to play with other dogs. Other litter - mom is a "velcro" dog and likes to be with her person rather than other dogs and dad is more dominant and stubborn. I'm drawn to the personalities of the first litter parents but I'm also liking the videos they've posted of the second litter puppies. How much is determined by their parents in your opinions?
