The staff at McMechen City pool is inviting you to come and swim all day long for just a dollar.
The event is called Pool for Paws
And that great deal comes from a small donation to help out animal Shelters.
The pool is asking you to bring needed items or to simply make a donation.
There will be games and giveaways all day long for family fun.
Pool manager Nikki Wilson says she hopes to raise around a thousand dollars for this cause.
