Danny played the adorable puppy Fred on I Love Lucy in the sixth and final season.
Danny, a cairn terrier, was owned by Frank Inn (1916 - 2002), an animal trainer who saved animals from being euthanized in shelters. He kept the ones with acting abilities, including Higgins who played Benji, and gave the others to friends and admirers as pets.
In 1957, he appeared on I Love Lucy as Fred, a puppy Little Ricky brings home. Fred, the Ricardos' friend and landlord, complains when the dog howls all night (the howling done by a voice actor), and a tenant is outraged by the noise and demands he be sent away. But stingy Fred can't resist the cute little dog named after him and chooses to let the Ricardos keep the puppy over keeping the tenant and money.
Danny also appeared in the film Pal Joey (1957) as Snuffy, the TV show Dennis the Menace (1959 - 1963) as Mr. Wilson's dog Fremont, the film Anatomy of Murder (1959) as Muffy, and the final Three Stooges short Sappy Bullfighters (1959) as Pepe.
