I have stumbled upon a water problem. I have a 9 month old lab that loves the water but not far out. I can throw marks out to 20 yards in the pond and she does fine but throw them any longer she goes about 5 to 10 yards out and turns around. And when I scold her she just cowers down to me and just shuts down. I've tried doing "fun bumpers" with her and it still not working. I think I started the problem by throwing my own marks so I got a buddy to throw them and we have been doing that for about a month now and nothing has changed. Also we don't let her come back without having a bumper in her mouth. Think it will change with age? Any suggestions would be a big help.
