The judges decision is final (so it says in the rules!)
We would have given up years ago, if we had taken to heart some of the comments the judge makes.
We show native ponies, and where we are based, there are a lot of welsh ponies, so quite often we stand out like a sore thumb with our ponies in among the welshies. And quite often the judge is a Welsh pony judge, and we know they will not look at our pony .....they should of course, each pony should be judged according to its breed standard.
You do get to know which judges like your pony, and which don't, and you just do not show under them again.
