Go look at seeing spots' profile, he is on there.When you first posted this you described him as spotty with a coloured tail and put a link to a pic (which didn't open). If you could put that description of him back up and especially a picture you might get more information. You did say you shared him - does your sharer have any clues? Or his passport?
unfortunately, i didn't. but thanks anyway xxYears ago they had Shetlands to work down the mines.
If you bought your pony at the sales it's a Hill Pony.
Why the connection with Dartmoor? If he was a Hill Pony the passport comes from that association on the day of the drift sale.He was bought at the sales. But he was bought at horse sales up here, not in Dartmoor as far as I am aware.
It just means unregistered. You only have to record part bred or purebred. But every horse has parents and the person who bred that horse knows the date, year and month. I guess they just couldn't remember the day.Mine are both of unknown breeding. But both had month and year but no actual day on their passports. How can you know how old a horse is if nobody knows who it's parents and therefore it's true date of birth?
