Zeeva, based on what you are describing, I would take your dogs to a lake where they can wade in before swimming to get them acclimated to water.
With my current dog, I introduced him to swimming on Lake Michigan... I just went in and started swimming away from shore, and, sure enough, Riley decided he wanted to follow. With my last dog, it was the same.
Both my last, and current dog, became avid water dogs... Riley beats most labs in speed to getting out to the ball I have thrown for him in the lake. Note: Anyone who knows dog beaches, knows that labs will try to poach any ball thrown in water. So, I am glad my dog always gets to "his" ball by out-swimming the labs : )
