do puppies need to be fully weaned before being sold
State Laws. Sixteen states require that puppies be at least 8 weeks old before being sold, and one, Virginia, requires that puppies for sale be at least 7 weeks old. Some states mandate that a puppy be fully weaned before being sold, which may occur later than 8 weeks for some pups.efore 8 weeks of age, a puppy needs his mother. The legality of selling a puppy younger than 8 weeks old depends on breeder's state or city laws. Even in areas where it is legal, buying or selling a puppy before he has reached the 8-week mark is generally not a good idea for a wide range of reasons.
