Otho was bred by the Honourable Richard Vernon of Newmarket, who also bred the Derby winner Diomed (ch c 1777 Florizel). He was later sold to the Earl of Upper Ossory, of Ampthill Park, Bedfordshire. He was on the turf for four years where he defeated such horses as Turf (b c 1760 Matchem) and Antinous (ch c 1758 Blank).

Otho was a private stallion for Lord Ossory until 1778 when he covered publicy for 20gs. In 1780 his fee declined to 5gs and remained there until 1784. In the stud he got a number of excellent runners for Lord Ossory. His most famous son was Dorimant (ch c 1772), a notable racehorse and sire. His daughter Otheothea (br f 1772) was the ancestress of a number of good horses, including the One Thousand Guineas winner Kate (b f 1849 Auckland). Another daughter, Pastorella (b f 1774), was the ancestress of the St Leger winner William (b c 1811 Governor), and his daughter Nelly (b f 1779) was the ancestress of the Prix Royal Oak winner Nelusco (b c 1865 Monarque) and other good winners.
