There are several reasons we suggest this. During the last weeks in the litter (week 6 -12) puppies learn their basic social skills from other littermates. These are the behavior skill that they will use for the rest of their lives.
As a result this time makes a HUGE difference in the way a puppy deals with people and other dogs. They learn everything they need to know from littermates and from mom. If they play to hard or to rough, the other pups will let it know.
Mom will also teach the pups how to behave correctly. Separating the puppies any earlier than 8 weeks usually results in behavior problems like biting, jumping, barking and other things.
