In Lancaster County, a riding club used their horses to help police officers.
Horses help officers with things like crowd control and sometimes to chase suspects.
"Our goal is to provide a nice venue where people can come and see the police horses, talk to the officers, see a canine in action which most people unfortunately never do, and enjoy these beautiful grounds and come and enjoy as a participant or as a spectator the horse show," Riding Club member Mary Glazier said.
Organizers say caring for the animals can be expensive.
All of the proceeds raised from advertisements and event sponsors will go to the Lancaster City Police Foundation, which will help with animal care, canine training, as well as transportation for horses.
