Well I had a private lesson today, and my instructor wanted me to try Thumper in a pelham bit. He has a super hard mouth from the bit his breeders rode him in, although he's been getting better. Anyway, we flatted in his normal copper oval-mouth eggbut snaffle and then switched to the pelham for jumping. We won't use it all the time, just for shows when he gets a bit strong and every once in a while to make sure that I'm still able to ride in it correctly (as in on the snaffle rein the majority of the time). He didn't rush at all, because I was able to just check him once before each jump and then just ride, instead of half-halting hard every two strides.
So that went really well, and then I also found out that Thumper's jumped 3'6", which I'm thankful for because my trainer will be able to give him a refresher over higher jumps while I work up to that height, as I'm definitely not ready for 3'6" yet!
*This part is a rant*: Okay well Thumper is a TB/Mini cross. My trainer gave me a ride home, and on the way she said that they had got him directly from the breeders, and it definitely WAS an intentional breeding. They stand Miniature Horse stallions at stud and breed them to TB mares, in order to "create a smaller horse for women to ride". That's pretty much their belief, sadly enough :S. And not only that, but they rode him in a corkscrew snaffle every single day and then switched to a pelham for showing. And I now know the reason for his near-bomb-proof-ness: they had chickens running around in the arena. When my trainer asked about this, they responded, "Oh, it's okay, he's used to it." and then said, "They'll get out of your way!" What I don't understand is why they would intentionally breed a TB/Mini cross. There are enough unwanted horses out there, and I'm sure most people would just pass over an ad for one of these crosses in an instant. Granted, Thumper does have decent conformation (he just won first in halter two weeks ago) and is balanced overall, so I'm thankful for that... okay rant over! :)
Oh and if you read all of this, thank you
