Danamo's Marilyn Monroe Online has a fact page devoted to Marilyn's Pets. Her dogs included a spaniel, a collie, a basset hound, and a chihuahua.
She is pictured here with her last dog, Maf Honey, a Maltese given to her by Frank Sinatra. She named the dog "Maf" because of Sinatra's mafia connections. Maf was a pampered dog who was even allowed to sleep on Marilyn's fur coat, and was Marilyn's pet until her death in 1962.
