Animal control officers seized 27 horses from Celtic Ranch in Graham after they received a complaint about the treatment and condition of the animals.

The ranch lists itself as a rescue online and according to their website they, "take a natural approach to rehabilitation for horses and humans by promoting natural initiatives to serve both."

Animal control, members of "Save a Forgotten Equine" and the Seattle Mounted Police Unit rescued the horses on Monday.

All 27 horses were transported to another pasture where they are being evaluated by a veterinarian to help with the investigation. The sheriff's office said they can't release specifics on what lead to the investigation but that an animal cruelty investigation can started for anything including neglect, abuse, lack of care or failure to get medical attention.

The investigation is ongoing.
