Okay so, here's the situation: my boyfriend's sister has this horse. She's a 13-15 year old (at least that's what he said) QH X Appaloosa. She's a gorgeous horse. But I feel really bad for her. She (my boyfriend's sister) is unable to ride her - she's pregnant.
She (the horse, now) has lost so much muscle just sitting in their pasture. She has little to no muscle on her rump and absolutely zero back muscle. You can see her ribs, but not too horribly; I don't think it's from being underfed - she's one chubby horse. Haha (Can someone say "Grass belly" ??)
But I offered to start riding her for them, mainly to give her something to do, and also partly because I'm suffering from not enough horsey time. What are some things I could do/work with her on starting out to help her gain her muscle back?
Thanks in advance.
