I could make an association tomorrow called the "Bay horses with stars" and start giving registrations. It doesn't mean that the horse is worth more. It just means the horse is bay and has a star. Half the horses I register would probably be brown anyway.
Who said anything about it being worth more? And the OPs horse is very clearly paint. Pinto is a large organization with it's own 'Pinto Worlds' and 'Pinto Congress'. How many pinto horses have you seen aren't really pinto? Irrelevant point.
Colour registries are all well and good, but the only registry I would ever care about is the relevant breed society. They require some sort of proof that the horse is the one on the paper, usually a service certificate or something similar, but some are swinging towards DNA typing too. They keep accurate results of the horse's lineage, and of ownership.
He doesn't have a breed, as he is a cross. DNA typing? Really? Do you realize how ridiculous and pompous you sound? The OP has a grade horse and wants showing opportunities, not for him to be registered and branded with as an Oldenburg, or for him to be worth $$$. Jeeze. Besides, you can snob on color registries as much as you like, but many warmblood registries care little about the actual breed and are more about 'type'. A good way to get a certain type of horse (sport horse) but an easy way to lose foundation breeds.
Lineage and pedigrees are pretty moot in a non-breeding gelding, anyway. No offense to the OP but I'm pretty sure he won't be winning an Olympic medal, so his pedigree is of no interest to breeders.
Colour registries take any horse that is the required colour - and don't need much in the way of proof of identity of the horse. So I could take the OP's horse, that she (for example) registered with the "Big and Boldly Marked" body. Since they don't need me to prove that I own him, and that he isn't already registered, I can re-register him in my name. No one knows that I don't own this horse then.
Oh please. This is a stretch--there are dishonest people in EVERY breed registry; there is no way to police honesty. You should see some of the things that go on with dishonest warmblood breeders.
These horses have no 'proof' because... they can't be registered in normal registries. They're grade. How would you suggest the OP prove he's her's? A bill of sale? Anyone can forge that, and most grade horses don't even have one. So? Any bright ideas? Think the Pinto Association should require DNA typing? *laughs* Doesn't prove anything.
There really IS no way to prove who grade horses belong to. So the OP is trying to get a set of papers on her horse... that maybe, perhaps, do the same thing that my APHA papers do in the fact that they help prove he's mine? You're point is hypocritical; some of these registries have merit and are trying to prevent a problem you seem to think they cause. I agree that there are many silly and ridiculous registries (walkaloosa!), but the Pinto Association isn't one of them.
Bigger registries like Pinto open up MANY showing opportunities that the OP would not have had--not only can she go to 4H now, but she can go to all Pinto shows and now has a chance--if her horse is talented--to even take him to the Pinto World show, as they have MANY classes for all breeds. Dressage too!
Methinks thou dost complain too much.
