An accomplished equestrian, Dodge also founded the Spring Valley Hounds, a hunt club that not only conducted hunts for their members among the many estates nearby, but also held a major annual horse show in New Jersey. Competitions included those for hunters and open jumpers, as well as for saddle horses of three and five gates. Many of the competitors followed the international horse show circuit that closed its season with the November exhibition at Madison Square Garden on Fiftieth Street and Eighth Avenue in Manhattan each year. Nearby, the United States Equestrian Team formed for the Olympics from these ranks in 1950, it was founded just off of Spring Valley Road, on van Beuren Road at the Coates estate.
