My choc. lab brings things to me that I have dropped. The other night I was folding socks and dropped a pair directly under the center of the table and couldn't reach them. I called him into the room, pointed to the socks and said, bring them to Mama." And he did. He's picked up my cell phone, the remote, the regular phone - all kinds of things. He does not like to pick up small things like tweezers.
He brought me something once on his own and I just praised the heck out of him and he sort of taught it to himself from there.
