The YMCA of Beaufort County will host a free Puppy Plunge from 10 a.m. to 1 p.m. Saturday. After the kickoff event, dogs of all breeds and sizes are welcome to attend Puppy Plunge events on the first Saturday of each month until the spring. Cost is $5 a dog, and all proceeds benefit the "Learn to Swim" program at the YMCA. Dogs must be well-behaved, current on all required vaccines and on a leash until inside the pool area. Owners must be present at all times, and humans are not permitted to swim in the Puppy Plunge.
