Handling history sets the starting point
Dartmoors range from well-handled children's ponies to hill ponies who have barely been touched, and your starting point depends entirely on which one you have. If leading, halting and standing beside a person are still new, trailer training is premature — teach those first, in a small enclosed space, until he follows, stops and stands without tension. A pony who trusts the rope will consider the ramp; a pony who is still deciding about people will file the trailer under threats. Keep early sessions very short and end them while he is still relaxed and curious.
Set the trailer up for a small pony
A trailer arranged for a big horse can unsettle a Dartmoor: partitions high and wide, a steep ramp, a long dark step up. Lower the ramp angle using level ground, make the ramp surface quiet and grippy, open the front and sides for light, and consider travelling him in a space that feels proportionate rather than cavernous, secured as the trailer is designed to be used. Place a hay net where he can reach it once inside. Check nothing dangles, rattles or flaps — small ponies notice details, and a breast bar at the wrong height is worth sorting before he ever walks in.
Tiny stages, repeated without pressure
Lead him around and past the trailer until it is ignored. Then ask for a stand at the ramp, a sniff, a single foot placed on it — and reward and walk away. Dartmoors are thinkers; given time to look, many walk up on a loose rope once the ramp is understood, while pressure from behind tends to produce a pony who spins or sits back. Let him retreat a step when he needs to and simply ask again, keeping your own body calm and to the side of his shoulder rather than dragging from the front. Progress measured across a week of short sessions is real progress, even when a single session looks uneventful.
Practise standing, doors and tiny journeys
Standing inside quietly is a separate skill from walking in. Build it gradually: stand with hay, a handler moving outside, the ramp raised for a moment, then down again before he asks. Only when standing is dull should the first journey happen — a few minutes, smooth roads, home again, unload calmly and turn out or feed as usual. Unload slowly; small ponies can be tempted to rush or even turn and jump down, so keep the rope, guide his quarters straight, and let him find the ramp's edge at his own pace. Each uneventful repetition is a deposit against the day loading actually matters.
Troubleshoot kindly and know your limits
If he will not approach at all, work further from the trailer where he can succeed, and check basics — is the ramp noisy underfoot, is the interior dark, is a stronger-willed companion calling from the field? Never load by lifting, dragging or crowding him into a corner; a frightened Dartmoor learns avoidance that lasts for years. If he panics, sweats and trembles rather than merely hesitating, or has never been handled enough to lead safely, bring in an experienced native-pony handler and consider whether he needs more general education before travel. A pony who suddenly refuses after loading happily also earns a physical check before retraining.
