Eighteenth President Ulysses Grant preferred horses above all other animals as pets, but he and his family members did have other pets with them in the White House, including two dogs. One was a Newfoundland named Faithful, but the other was a dog named Rosie.
Rosie was rumored to be a black-and-tan dog of no determinate breed. According to Seymour Reit in Growing Up in the White House, Grant would often take dinner in the stables and talk to both the horses and to Rosie while he ate.
Little more is known about Rosie – she stands a bit in the shadow of her bigger brother, Faithful. However, given both Ulysses and Jesse Grant’s love of animals, it is likely she lived a long and happy life with the family.
