More than 50 Tennessee Walking Horses—including pregnant mares and two weanlings—are receiving rehabilitative care after being removed from a Tennessee farm where they lived in allegedly deplorable conditions.

Giles County, Tennessee, Sheriff’s Department Chief Deputy Tommy Chapman said law enforcement personnel answered a call about a group of allegedly maltreated horses. On April 14, acting on a search warrant, investigators found 53 horses living on small lots filled with mud, water, feces, and urine, he said; in some areas, he said, the filth was more than a foot deep. Investigators also found two weanlings locked in a horse trailer without access to fresh water and standing on urine-soaked and feces-covered hay, Chapman said. Several goats and a dog were also found on the property, he said.

“The animals were not in good physical health,” Chapman said in a written statement.

Chapman said one horse was euthanized due to malnutrition, and 54 horses were removed from the property
