Dogs love to swim in swimming pools. However, chlorinated water is not good for dogs.The chlorine can remove the natural oils from the dog’s body and cause dry, itchy skin. Also, too high a sanitizer level can irritate the dog’s esophagus if it drinks the pool water. If your pool is sanitized by chlorine or bromine, keep the level below 3.0 ppm if you allow your dogs to swim in the pool.
