He did it! Bradley fetched for the first time. I don't think he intended to. He was lying next to me on the couch chewing on a toy. I threw the toy to the middle of the room and Bradley went to get it and came back. He started to chew on it again. I threw it again. He brought it back to chew on it. About the third time he expected me to throw it again when he brought it back. After about five times I quit throwing it because I didn't want him to get tired of the the game or get frustrated. He continued to lay there and chew the toy. Oh happy day!
