Spirit is a dog that was rescued more than 10 years ago.
The abandoned and abused dachshund mix was found severely burned at Oak Hill Cemetery in 2000.
She had been doused in gasoline and set on fire - requiring extensive veterinary treatment.
Since then, the Spirit Medical Fund has been established.
Hundreds of animals each year receive medical treatment paid for with money from the Spirit Medical Fund - which is only used for animal care.
Saturday, folks came out to the 2nd annual Spirit Festival to support the fund, and to ensure sick and injured animals continue to get the treatment they need.
Kristi Eggers with the Spirit Medical Fund says, "It's overwhelming actually to think about the about the animals that have been helped by her fund because what happened to her was so difficult."
The festival featured games, pony and horse rides, and a celebrity dunking booth.
Evansville Police Chief Billy Bolin and Vanderburgh County Sheriff Dave Wedding were among those who took an icy dunk for animal care.
But as you can see, they also took the opportunity to have some fun and knock each other into the water.
