You will be training your puppy from the moment you bring it home and start to house train. Puppies start learning from birth and good breeders begin handling and socialization right away. Some training can begin as soon as the puppy can open its eyes and walk. Young puppies have short attention spans but you can expect them to begin to learn simple obedience commands such as "sit," "down," and "stay," as young as 7 to 8 weeks of age.Formal dog training has traditionally been delayed until 6 months of age. Actually, this juvenile stage is a very poor time to start. The dog is learning from every experience and delaying training means missed opportunities for the dog to learn how you would like him to behave. During the juvenile stage, the dog is beginning to solidify adult behavioral patterns and progresses through fear periods. Behaviors learned in puppyhood may need to be changed. In addition, anything that has already been learned or trained incorrectly will need to be undone and re-taught. Puppies are capable of learning much from an early age.
