Odd couples: Cross-species friendships and empathy
Dogs and fish are known to form close friendships (see also this). I've written about a dog named Chino, a golden retriever who lived with Mary and Dan Heath in Medford, Oregon, and Falstaff, a 15-inch koi, who had regular meetings for six years at the edge of the pond where Falstaff lived. Each day when Chino arrived, Falstaff swam to the surface, greeted him, and nibbled on Chino's paws. Falstaff did this repeatedly as Chino stared down with a curious and puzzled look on her face. Their close friendship was extraordinary and charming. When the Heaths moved, they went as far as to build a new fishpond so that Falstaff could join them. Cross-species friendships, called odd couples, and empathy, are not all that uncommon.
So, I frankly am not sure what is going through the dog's head and heart and this video is a great catalyst for getting readers involved in the discussion. If you comment, please know that anonymous (and personal) comments will not be posted.
