Napoleon is very interested in the education of the young.Why do you think he took the 9 puppies to educate on his own?

Napoleon is interested in educating the young because the young have no recollection of the past. The young are easy to train with the ideals that Napoleon wishes, even if they are not the ideals that the animals discussed when forming Animal Farm. He sequesters the puppies so that they cannot have any outside influences from any other farm members, therefore the puppies loyalty rests solely with Napoleon- they have known him like a puppy knows his mother. This is Napoleon's powerful tool to subdue any insubordinate members on the farm, the puppies, who grow up, become ferocious dogs who do Napoleon's bidding.
