I know. I was really surprised by this when we got to the field, because he had been doing a really reliable retrieve to my hand in the house. We started with that in the field, short throws and put the ball in my hand. When we got to longer throws, he just stopped bringing it all the way back. Maybe it has more to do with the chucker; he seems to hate it and wants to kill it. We have a long handled shoe horn in our house that kind of looks like a chucker and he hates it too. I could try having him bring it to my hand, then put it in the chucker for the long throw. I just love to watch him run!I think the idea if teaching him to bring the ball back to something other tha. Yourself is a good idea. I think maybe he wants you to throw the ball but he at the same time doesn't want to give it up to you directly. Lol
Try teaching him to bring the ball to a basket or bucket. Start small if course and go for distance.
