nothing to do w/it. Going to a responsible, reputable breeder who will spend alot of time w/a person getting to know them and their lifestyle and then matching a puppy to that person and their family is the key. I'm not saying it's foolproof, but it is how it should be done.
People buying on impulse and buying from petstores, puppy mills and backyard breeders are asking for nothing but trouble.
Environment also plays a huge role on an Akitas adult personality...how it was raised, socialized, trained, etc....all have a huge impact on on the end result.
