From the Rowlett Wet Zone website:
It’s time to “let the dogs out” once again! Join Wet Zone Waterpark and the Friends of Rowlett Animals as we once again host Doggie Swim Day! Cost is $10 per dog, humans get in free! Each dog will need their Rabies tags or paper copies of vaccinations to participate. This year’s event will be hosted by Friends of Rowlett Animals and all proceeds from ticket sales will be used to assist animals in the Rowlett area.
