I never thought about saltwater, our girls have always swam in one of the Great Lakes or home in the pond. How do people keep them from drinking it?my gal-dog got to play in the ocean for the first time. She loved that but got a bit weirded out when her feet didn't touch the bottom. I didn't get pictures because I was busy trying to teach my gal about the beach, especially no drinking the water. I didn't want my dogs taking too much salt water.
