Hey Don, Just an update on Nala. She is starting to get better on the fetching. I found that she does the best when I have her on a lead at heal and throw 4-5 for Tucker without letting her move. Then she gets 1, Tucker gets 4 or so more, she gets one more and then the bumper goes away. She still wants more and is excited the next time the bumper is brought out. She also seems to have outgrown her carsickness. Here is a picture of them both.
