In this video filmed in 1988, Koko (age 17) is outside on a walk with Penny and Smile, a rescued dog that was found on a road nearby, tied to a bag of dog food. Koko named the dog Smile because he always had a big smile. In the video, Koko hesitantly pets Smile, and then continues on her walk. Koko is gentle with Smile, but it is clear from her demeanor that she is a cat person!
