When I worked in a dressage yard all the horses there were ponies too, especially Bars Grand Prix horse, he was definately a pony
Somebody came for an interview once and I was showing them round and she asked where the ponies were, and I had to explain that these big warmbloods were all ponies lol
Ironically I went to see someone just after that had 2 ponies (a Highland and a Shetland) and said to her I like your horses..... She replied they're not horses they're ponies
