His wife Emma stated in her book, "Mrs Charles Cruft's Famous Dog Book", published in 1949 that there was an unwritten rule that both herself and her husband couldn't own any dogs for fear of making others believe that they favoured one breed over another, even going as far to say "we were determined to own a pet, so we took the least line of resistance and kept a – CAT!" This was disproved in Cruft's memoirs, published posthumously in "Charles Cruft's Dog Book" in 1952, where Cruft explained that he had lived in households which had Alsatians and Borzois. He went on to make particular reference to the fact that he and his wife Emma had owned at least one Saint Bernard; the same breed of dog he had used in his creation of the Crufts logo.
