Ponies Teeth...

[SpringDanceJack]

Firstly, not sure if i'm posting this in the right one. But I'd like some advice.
I've recently brought my 6 year old niece a (as advertised) Grey 12.2hh, 10 year old, ex pony club gelding.
On viewing this pony I was very pleased with him, my niece was confident riding him, so I decided to buy him.
I did think he was bigger than 12.2hh but with my niece on him, she didn't look too small, so I wasn't bothered.
On arriving home, I measured him. He is in fact 13.1hh. The first time he was ridden home, he was much more forward than I remembered. I put it down to being ridden in a field instead of a menage, new home ect.
The second time he was ridden, he started bucking, spinning and napping. I put it down to the fact he had been on too much grass when he was used to being stable kept at night. So he's been in the stable for 2 weeks now. I have had his back checked as well, just to rule out any pain. Now today I've had my friend around, and her daughter (a very petite 16 year old) rode him, and he was terrible. Bucking, rearing, spinning and napping. BUT only in trot/canter. We decided to lunge/long rein him, in which we learnt he is a complete and utter novice. He didn't have a clue what to do. After a few big bucks and general misbehaving on the long line, he did settle and began to listen.
I decided to check his teeth after his workout. And he has wolf teeth. On researching this, I've found his teeth look more like a 5 year olds. On checking his passport. It seems to be a replacement. I've tried contacting old owners, to no avail. Has anyone else had a situation like this? And do we think hes 10 or 5? He also have a very high neck, which we thought suggested he was gelded late. But if he is only 5, it would explain this...

There seem to be several issues here, firstly the pony may or may not be as described, the passport may be a replacement or possibly one that has been used to sell a younger pony as a more desirable 10 year old.
The height is slightly irrelevant as you had the opportunity to see whether it was too big, even a full up 12.2 may well be too big and strong for a 6 year old, the wolf teeth are possibly causing a reaction but unlikely to be the main problem.

Why do you describe him as an ex pony club pony? that seems an odd description to be used for a pony.

That you cannot contact the previous owners of a supposed PC pony rings alarm bells to me, most genuinely outgrown ponies will be much loved and owners do like to keep in touch, that you have tried and failed suggests you have been sold an unsuitable, possibly barely backed 5 year old, you really need to get your vet in to check the pony to see how old he is, see if his microchip, if he has one, matches that in the passport, and that the markings match up, if they do not and he is only 5 then you need to look at your options which could be to try and return, reschool, sell etc, but until you know the full facts you will not really be able to know which will be best.

Vetting when purchased would have given you the information that you now require but you now have less chance of getting a good outcome if the pony is not the one you thought you were buying.

Be Positive has pretty much covered it all! I would add though, not all wolf teeth cause problems, book yourself a Vet visit to confirm age, therefore you will have comeback. He may never have been long-reined so that wouldn't worry me.

Have you spoken to the person you bought the pony from?
