Florence Nagle (26 October 1894 – 30 October 1988) was a trainer and breeder of racehorses, a breeder of pedigree dogs, and an active feminist. Nagle purchased her first Irish Wolfhound in 1913, and went on to own or breed twenty-one United Kingdom Champions. Best in Show at Crufts in 1960 was awarded to Sulhamstead Merman, who was bred, owned and exhibited by Nagle.
