An Oklahoma man accused of animal cruelty after allegedly using an all terrain vehicle to drag his horse down a gravel road has pleaded not guilty to the animal cruelty charges against him.

On Nov. 10 Sequoyah County, Okla., Sheriff’s Department personnel responded to a tip about a severely injured horse tied to a tree. Deputies later learned that the horse’s owner, Reuben Houston of Vian, Okla., had allegedly tied the horse to a 4-wheeler and dragged it down a gravel road. Due to the severity of its injuries, the animal was humanely euthanized by a veterinarian.

Houston was charged with animal cruelty in connection with the incident. He was also later charged with malicious injury to property under $1,000 and trespassing.

Sequoyah County District Court records show that on Nov. 16 Houston pleaded not guilty to all the charges against him
