~ It may not have been weaned properly. Puppies should not be taken from their mothers until at least 8 weeks old. They should still be nursing from their mother and gaining immunity from her milk and antibodies, until fully weaned. It takes a couple of weeks at least, for them to be introduced to puppy food, and during that time, they still rely largely upon their mother for their nutritional needs.
~ Puppies naturally learn from their mother, not to soil their bedding area. Take a puppy too young, that hasnt yet learned that, and it's going to be difficult to teach it the rights and wrongs of toileting. Their mother teaches them basic hygiene matters.
~ Puppies learn to socialise with other puppies, how to play and explore their world, and other doggy behaviours, from their litter-mates and mother. Taken too young, will put the puppy at a huge disadvantage as far as learning how a puppy is supposed to behave. They need their mother and littermates to learn what behaviours are acceptable. Removing a puppy too early from its mother and littermates, is often the cause of social and emotional difficulties as the puppy matures - they can include iver-activity, increased anxiety, stubborn behaviours & aggression, excessive barking, separation distress and compulsive destructive behaviour towards other dogs, humans and their belongings.
..... Plus it's cruel and puppy will be more confused and sad to be removed from the only family he/she has known.
