More: River is an old soul, sweet, loving and funny and a good big brother to his younger retriever siblings. Despite being a larger built lab he's very fast and in great shape. In this photo he is running in the National Forest near our cabin in South Park Colorado. He can run as fast as his 3 year old siblings after a bunny, bird, squirrel or chipmunk. And, like all labs, he always knows when its dinner time!
