One man was arrested and 17 dogs were seized in a suspected dog fighting operation, according to the Humane Society of the United States.
HSUS' Animal Rescue Team said it assisted the Jacksonville Sheriff's Office in conducting the investigation.
Investigators said the dogs rescued have scarring and injuries consistent with dog fighting, including some with mutilated faces. Suspected dog fighting paraphernalia was also found on the property, investigators said.

"The HSUS is committed to eradicating the sadistic sport of dog fighting, which maims or kills thousands of dogs every year," said Chris Schindler, manager of animal fighting investigations for HSUS.
"The Jacksonville Sheriff's Office was happy to work with the Humane Society of the United States and assist them in bringing the investigation to a successful conclusion," said John Hartley, director of investigations and homeland security for JSO.
HSUS said it brought a mobile crime lab and assisted with the examination dogs on the scene. Experts from HSUS were on hand to help identify and document evidence and coordinate the rescue effort. Hello Bully assisted HSUS in handling and documenting the dogs, and the Animal Care and Protective Services of Jacksonville assisted in the raid, helped with the transportation of dogs and supplied the veterinarian on the scene.
Dog fighting is a felony in all 50 states.
