Belle, Sebastian and the Horses was a children's television programme from 1968.
[1] It was filmed in France as Sébastien parmi les hommes as 13 colour episodes, and re-titled by the BBC.
Things soon get complicated when Pierre's rich fiancée finds out about Sebastian's existence.
The English title may be a slight misnomer as the dog Belle only appears fairly briefly, she is separated from the horses after she reacts negatively barking at them.
It was not quite as successful as the earlier series, although it was repeated a couple of times by the BBC after its first screening in late 1968, and also shown once by RTÉ.
