Trust me, socializing an Akita only goes so far, then BOOM...

Hoping you can "train" an Akita to run with a pesky Corgi & a shy Saint is not realistic -- Any reputable & responsible breeder will tell you the same thing that Jer-Mars did ... Your situation is not a mix into which I would add an Akita of either sex.

This is nothing against you as a dog person, a dog lover, a dog trainer, or even a "dog whisperer" at all <:-) It's just that someone who has never raised an Akita before simply has no idea what they're up against in terms of the great potential for dominance behavior & dog-aggression in living circumstances such as you describe.
