Sucks back off contact
I recently got a lease horse off a mate of mine for my dad to learn on. He's a 20 year old tb gelding, very much been there done that type (has done dressage up to elem-trained some medium, western, hacking, jumping, he neck reins etc. etc) and is pretty much as close to bombproof as you can get. He's just such a gentleman!!
He has been out of work for the past 12 months due to injury (long story, where he comes from they have a really bad fly problem, the flies eat into horses and leave massive wounds that don't heal. Gucci had this in the corner of his mouth) which has now totally healed.
I've been riding him for the last couple of weeks lightly to see how he'll go for my dad, and he's just a joy to ride, so much fun! I'm not used to having push button, educated horses it's fantastic! The only gripe I have with him, is that he goes in a very typical frame of a horse that sucks back off the contact.
If I was my horse and I was going to be riding and competing reguarly, I would want to nip this in the bud ASAP, however because it will be my beginner dad's horse, I'm not sure whether to just allow him to continue working like this. He is almost 21 and everything else about him is lovely.
My dad really enjoys riding him because he's so light in front and so it feels to dad as though he has more control. I know it's not correct, but is there really any harm in letting an old horse go around like that with a beginner on board?
