Yeah, Coltrane wasn't too big on water when we were at Lake Michigan... I think the waves scared him. That changed when we went on vacation in Alabama... There was a very shallow stream and the water hardly moved and he decided to jump in. We also went to a calm lake and he went swimming. Now he is always looking for a way to jump in the tub, and waits by the door if he hears water running. ... so maybe a calm water, where your dog can choose to go in? idk.
I did videotape Coltrane in the tub though, because it cracks me up.
