I've seen those competitions before, look like a lot of fun..Yea, if you can get the back end to keep from sinking, you would do great..Buck was a champion swimmer and we did teach him to fetch in the water. He also learned how to retreive under water as well...Now in an open space, like the ocean he will not give up! I swear I thought I was going to have to have the ex dive in and save him once, he refused to give up on this stick that kept getting further and further away....
We used a lot of floatable toys to work with Buck and he really enjoyed it a lot. I know that you can get life jackets for dogs, but honestly I can't recomend one over the other. Maybe someone else on here has used them and can give you an idea. I'd say just keep working with her, make it fun, entertaing, but make sure you let her rest, it is incredibly hard work for them to swim and the last thing you want is for her to get too exhausted...
