Puppy raising

I apologize if this has been asked before. I am a veteran and have always wanted to be a puppy raiser for an organization that supplied service dogs to veterans. I had started training a puppy for my older brother before I had joined the army, and ended up keeping her to myself. my brother at the time decided he didn’t need her. She’s amazing.

Amyways, she has helped teach many other puppies great manners and confidence, and I want her legacy to continue.

If anyone can point me towards veteran organizations that are reputable I would greatly !
