The donkey suffered from overgrown hooves. The sheep needed shearing. The animals lived in mud and dirt and did not have access to a grazing pasture.
Officers observed concerning conditions, including unsanitary housing, a lack of potable water and an absence of veterinary care.
The animals, which have yet to be surrendered by their owner to the Pennsylvania SPCA, will remain in the non-profit's care as the investigation of animal cruelty and neglect continues.
The animals currently reside at the organization's Danville and Philadelphia locations and are being examined and cared for by a local large animal veterinarian and the shelter's medical team.
