Es amigo de Mickey Mouse y es el novio de Clarabelle Cow. Horace apareció primero como el caballo de Mickey en The Plowboy en 1929. Desde entonces, apareció como un sabiondo caballo antropomorfo. Horace ayudó a Mickey en sus aventuras en los libros de historietas antes de que el personaje de Goofy fuera creado.
Después de dejar los estudios Disney, Ub creó un personaje similar a Horace, para sus propios estudios. Hasta le dio casi el mismo nombre.
Horace nunca fue más que un personaje secundario, aunque protagonizó numerosos libros de historietas en Europa.
En la televisión, apareció en algunos segmentos del programa Mickey Mouse Works. También aparece en House of Mouse como un técnico mecánico.
En el videojuego Epic Mickey, Horace trabaja como detective privado en el Páramo. Horace manda a Mickey hacer misiones o ayudarle con su romance con Clarabelle.
