I can't imagine that feeding oil that infrequently would have a significant effect on his weight; I don't think the owner would want you feeding him extras without her knowledge; and it's probably best you know what everything he's actually being fed before you start trying to add things. Maybe speak to the owner about your concerns, and ask why she's chosen not to add anything to support weight gain.
(Being nosey, but the horse isn't a palomino sports horse type in Essex is he?)
I will speak to the owner about this as tbh it’s just annoying me how everyone comes after me for his swayback whenever I show pictures but I think I’ll lay of it and have a chat with his owner also He isn’t xx he’s a lovely dark bay lol more closer to Kent than Essex being over dartboard bridge
Thank you though I think my paranoia was getting the best of me and all the people getting to my head I Geuss I needed to have someone knock some sense into me lol it’s just a bit hard because when everyone always has something nasty to say bout him
(Ah, if I had a dollar for every swayback stallion on part loan, I'd have two dollars. Which isn't much but it's weird that it happened twice.)
Just explain to whoever's bothering you that the vet's happy for him to be worked, so they shouldn't be concerned. This thread may also be good motivation going forward.
It’s ironic isn’t it lol and thank you again I’m just now realising how badly I’ve let these people affect me when the horse is happy I’m happy so there really isn’t an issue except for his occasional play up in the school
Although a good topline is of course to be preferred, sometimes you just have to work with the prerequisites the horse have. Occasionally it can still work quite well.
I know it's not the same as a swayback, but the Swedish show jumper Bonzai H, ridden by Helena Persson, became somewhat known for his "a bit" awkward looking topline. They had a saddle completely custom made to fit how his back was built, and he competed for 12 years in 1.50 - 1.60 classes, altogether he competed as a show jumper for 15 or 16 years, had victories in Nations Cup, a Swedish Championship, got placed more than once in international Grand Prix classes, participated in one European Championship, and was our team reserve in several other international championships.
He started his showjumping career by winning Swedish Breeders Trophy as a 5 years old, according to what I've read only had his first ever injury requiring a little bit of time off when he was 19 years old, and afterwards continued to compete for about another year or so. He really enjoyed being out competing, and apparently got very bored when not being allowed to compete in showjumping.
