My son has a Black Lab, about a year old. He bought the dog one of those kiddie pools about ankle high, so the dog could cool off. They have a bigger pool for the kids, about waist high. It kept getting all sorts of black hair in it. One night my son walked out on the back screen room and saw Lilly shoot up and into the pool, play around in the water and come sliding out like a seal! Night time is her favorite time, when no one is watching!
