The information below is from a site that is focused on show and pet homes:

Mostly 1’s: Strong desire to be pack leader and is not shy about bucking for a promotion. Has a predisposition to be aggressive to people and other dogs and will bite. Should only be placed into a very experienced home where the dog will be trained and worked on a regular basis. Stay away from the puppy with a lot of 1’s or 2’s. It has lots of leadership aspirations and may be difficult to manage. This puppy needs an experienced home. Not good with children.

Mostly 2’s Also has leadership aspirations. May be hard to manage and has the capacity to bite. Has lots of self-confidence. Should not be placed into an inexperienced home. Too unruly to be good with children and elderly people, or other animals. Needs strict schedule, loads of exercise and lots of training. Has the potential to be a great show dog with someone who understands dog behavior.

*Mostly 3’s Can be a high-energy dog and may need lots of exercise. Good with people and other animals. Can be a bit of a handful to live with. Needs training, does very well at it and learns quickly. Great dog for second time owner.

Mostly 4’s: The kind of dog that makes the perfect pet. Best choice for the first-time owner. Rarely will buck for a promotion in the family. Easy to train, and rather quiet. Good with elderly people, children, although may need protection from the children.  Choose this pup, take it to obedience classes, and you will be the star, without having to do too much work! -- The puppy with mostly 3’s and 4’s can be quite a handful but should be good with children and does well with training. Energy needs to be dispersed with plenty of exercise.

Mostly 5’s: Fearful, shy and needs special handling. Will run away at the slightest stress in its life. Strange people, strange places, different floor, or ground surfaces may upset it. Often afraid of loud noises and terrified of thunderstorms. When you greet it upon your return, may submissively urinate. Needs an incredibly special home where the environment does not change too much and where there are no children. Best for a quiet, elderly couple. If cornered and cannot get away, tends to bite. -- Avoid the puppy with several 6’s. It is so independent it does not need you or anyone. He is his own person and unlikely to bond to you.

Mostly 6’s: So independent that he doesn’t need you or other people. Does not care if he is trained or not - he is his own person Unlikely to bond to you, since he does not need you. A great guard dog for gas stations! Do not take this puppy and think you can change him into a lovable bundle - you cannot, so leave well enough alone.
