DON'T THROW RILEY IN.
My Bess jumped in and swam like a fish the first time she saw unfrozen water at about 5 months age.
Puff like to splash and wade but didn't know how to swim and had to be carefully taught.
I taught Puff to retrieve first and then used that to get her to go farther and farther out in the water.
While Bess had so much buoyancy her back and the top of her tail were visible above the water's surface, Puff (field line) has so little that only her neck and head are usually visible. I think that has a lot to do with the differences in swimming interest.
We use Lucky Dog vinyl 2" x 12" Training Dummies to which I tied a 30 ft. string or line; the line was useful in retrieving the TD in case I threw it too far for Puff to be comfortable retrieving. It saved me having to wade in to get it. (One source of TDs is

I threw the TD into progressively deeper waters.
When Puff DID dare to try to retrieve the TD, it quickly became apparent what much of her problem was -- she was in a vertical position, so frantically flailing the water with her front legs she created a moving geyser just in front of her but wan't using her back legs at all to swim.
I bought her a canine life vest to level her out and that helped a lot -- she learned to use her back legs.
She still was not that enthusiastic about swimming but she had no choice on the training. I love sail and if she was to accomapany me as my first mate, she needed to learn to swim.
It took all of one summer and much of the next with daily swim practice before she was comfortable swimming. She now goes in and swims without the life vest.
