From the Independence Police Dept's Facebook page:
"Yes, this really happened today! Each day is different for a police officer but this definitely doesn't happen very often. Officers were dispatched to 23rd and Harris to assist Animal Control on an unusual call. Someone thought it was suspicious when they saw about 20 dogs in a car. It turned out that these rescue dogs were all well taken care of and just on their way to a dog show. They are all trained and apparently have their own special talents. Some of the little ones are still in training and only know how to give kisses."
Don't worry, "Ponch" was safely taken into custody and is now hanging out with the nice people of SF Animal Care where he will hopefully be reunited with his owner.
