Austen Gives Adler Treats

Austen is getting the hang of giving Adler treats. He doesn't like you to put the treat in his hand. He has to pick it up off the gound and then hold it out to Adler. I'm wondering how he knows its not food for him and try putting it in his mouth, but he hasn't. He just holds it out to his patiently-waiting puppy who is ever so gently in trying to pry that treat out of his hand without hurting her little brother.
