Yee-ouchies.. scary thought that she is 2 1/2 and was exposed to a Stallion. I hope she isnt pregnant. She does look Pot bellied in that first pic, but normal in the second and third pictures.
As far as weight goes... I tend to keep my horses at a weight where you can -barely- see the very top of the last three ribs when their coat is completely shedded out. A lot of people would think that mine were underweight because of this. But their rears are rounded, chests are full, backs are flat.. so they are completely healthy! =) She looks like she needs some toning (around her neck), and i would make sure she is getting the -right- groceries because of her growing body.. but dont keep her too fat or else that will stress her joints out. Again, just make sure she is getting the right food.. not a lot of the wrong food =)
Also due to the weather changes in the winter, you should up the groceries a bit more because the horse needs the extra energy and fat to keep them warm during the nights.. I usually just up the amount of Coastal (Grass) hay i give since the hay churns in their gut and keeps them warm (sounds weird, but its true!).
Since she is a walking horse, she has a different build than a regular non gaited horse. Walkers arent supposed to have HYOOGE booties, and their haunches have a longer angle on them which could make them look untoned/weak/thin, but its really just the breed. If her rear looks like that of a Quarter Horse, thats when i'd be worried, LOL!
I kept my guys on Seminole's Mare and Foal until they were 3 because it was almost a complete feed. It was -perfect- for getting them what they needed without over supplimenting.
Beautiful mare, by the way =) My Dreamer is a Spotted Saddle Horse too!
**Edited to add**
I would like to see a front and back picture of her too. In that top picture it looks like i can almost make out her spine as it leads into the haunches. If that is true, she does need more weight. As i said above, make sure its the right weight.. you'll need to feed something that will specifically help her fill out up top (i usually give alfalfa pellets to help get the back weight). Also, do you have a picture of her from the butt and one from the front? those are also tell tale pictures that could really show if she needs the weight or not.
