Friends. Falstaff, a 15-inch orange-and-black koi, lived in the pond. Chino, a 9-year-old golden retriever, did not. But every day, Chino would pad out to the pond and peer into the water, waiting for Falstaff to appear. Falstaff would swim to the surface, offering what seemed like a finny greeting. Together, the inter-species pals forged a strong bond.
