Local clergy members administered the blessings at different events held around Chicago.
Owners were able to bring their pets to any of the designated times and receive a "blessing". Some CPD officers even brought their patrol horses.
Members of the clergy say the blessing is to recognize and embrace the emotional bond that people have with their pets.
