I'm not really planning on showing but I am really interested in how my new baby measures up. To me she seemed a bit underweight when I got her and she has gained some since this pic. I'm working on training her and am wondering what I can do to build her muscles and help her fill out to her potential. Thanks for the help.
Age? Breed? I agree she could still use some more weight, but IMO she really needs muscle more than weight.
Depending on her age, riding hills can be a great way for a horse to gain muscle. Also exercises like cavaletti make them use their stomach muscles, which helps all around. However she looks quite young, and these things would not be recommended for a horse that is still growing.
Then at this age I would just make sure you are feeling her well and let her grow up. Her muscle will come with age. If she is broke keep things short at this stage in the game, as she is still fairly immature and just needs time to fill out and grow up.
I would definitely not rush her under saddle training, as she has a bit of a long back and somewhat long pasterns and fine bone... So slow and easy will be best for her at this stage.
She is pretty weedy for a 3 year old. She may come with age.. but she may not. Light on muscle and bone. Hocks are nice and low. Back is long and weak. Not much rear on her. Well defined withers. Low set to the neck. Steep shoulder. Tied in a bit at the knee. Point of shoulder placed lower than I like.
I would get her started under saddle but no real riding until she is 4. She may not improve a lot in looks but she may. If not, at age 4 I would start working her fairly regularly and see if she improves (most will if ridden correctly at least 4 days a week).
She has more weight but she still has light bone, tied in at the knee, small round hocks, posty hind legs, low neck set, low point of shoulder and a long, weak back. Is she a bit less weedy? Yes because she has more weight on.
