The HSUS and other area organizations assisted the Randolph County Sheriff’s office in the rescue of mostly Great Pyrenees dogs. Many of the dogs were found outdoors, without any protection from the freezing cold, while others were living on piles of feces and urine inside the home. Some were suffering so severely they needed immediate medical care. Others were emaciated and so matted they couldn’t move. All of the dogs were removed from the property and thoroughly examined by a team of veterinarians. They received any needed immediate medical treatment at the Humane Society of Saline County. #
