Would you join a gym if they had "a dog" to swim once or twice a year?
Is this an incentive to join a fitness club? My YMCA runs a program as a pilot before draining the pool this week for maintenance.
Eevn if I a dog, I assume the dog days Public swimming pool at the end of the season. It's funny. Go see! As a selling point, but I think is valid.
