INDIAN RIVER COUNTY, FL (WFLX) - Three injured pit bulls and a puppy, suspected of being used in illegal dog fighting, have been rescued, according to the Indian River County Sheriff's Office.

Deputies say they also found cocaine and marijuana. They also seized over $900 in cash.
Detectives said two aggressive dogs had to be tranquilized.
