wonderful w/children when they've been raised w/children AND when the children have been taught how to respect animals and not to taunt and torment them.
I think it's great that you are interested in an Akita Rescue. There are hundreds of Akitas in need of good homes and alot of them come from owner turn ins so the dogs past history is known, such as if they are good w/kids, other dogs and cats, etc....
Depending on the sex of your dog at home will depend on the sex of Akita you should bring into your household.
Akitas as a rule are same sex dog aggressive, and can even be aggressive w/dogs of the opposite sex if both dogs have alpha personality types.
Again, Rescues do have Akitas waiting for homes that get along well with other dogs.
I suggest you do alot of research on the breed then contact some Rescue Organizations if you are still interested.
Here are a couple links for you to check out that are filled w/info to get started on.
