There are Akita Inu's about? so dont know where the rare comes from?
health issues for the Inu
Autoimmune Disease

I would recomend you contact the breed club for more information.

The Kennel club at the moment require hips and eye. taking your dog to the vet and just getting a check over is not enough, you need the required tests done for this breed to prevent any possibility of breeding from carriers

I would say if your dog is a good specimen breeders will contact you for use of your boy, a good breeder will NOT breed from a dog that has not proven itself to be of quality, or at least been looked at by people with experience in the breed who know what they are looking at, a good breeder will not allow you to use your boy on their bitch if he hasnt passed with flying colours on health test, he should also be at least 2 years old before using him.

Why cant you contact his breeder to ask these questions? are you not supposed to be breeding from him? has the breeder placed endorsements on his registration with the KC and so not given permission for him to be bred from? if not then I think you are out of order seeking to breed with him when you KNEW he was not supposed to be bred from, sorry if I have read your post wrong but this is the impression I got from your post.
