The property owners called the department around 10:30 a.m. Saturday after finding a badly injured stray roaming their land.
According to Sheriff Kelvin Williams, this is the second time in the last few weeks an abandoned pit bull has appeared on the same property but it's unknown if the dogs originated from the same place.
The dog, found Saturday, was discovered with major injuries and could possibly be involved with an underground dogfighting ring.
A deputy arrived on scene and the property owner eventually transported the dog to the Animal Medical Clinic in Cleveland.
"We will continue to investigate this case and find out as many details as we can," said Williams. "If people know of any organized dogfighting going on, we urge the citizens to call us with information.
"We are not knowledgeable of anything in Bolivar County but if we learn about this activity, we will locate those involved and prosecute them to the fullest. This behavior will not be tolerated."
Clinic Dr. Allison Bradshaw, who was unavailable for comment before presstime, took in the pit bull on emergency notice.
Williams said the dog was alive when it was brought to the clinic, but the dog's injuries were so severe it needed to be put down.
"Again, we will not tolerate dogfighting," said Williams. "It is illegal and cruel and we do not condone it."
