I just bought this horse, her name is Maddie. She's 6 years old, 15 hands and about 985 pounds (using the height/weight tape). No one really knows what she is, except part Appaloosa for sure (freckled lips, whites around eyes, spotty in places!). Her previous owner told me that the vet thought she might be part TWH because of her build. I'm having my own vet come out this week (I know...I should have done that BEFORE I bought her, but it wouldn't have mattered anyway. It was love at first sight!). The place I keep her is a roping ranch with a bunch of cowboys and HUGE thick quarter horses. They seem to think she's "poor" and underweight. I think she could use some pounds too. But could it also be her breed? She does have a pretty poor top line with lots of wither and spine though. I'm trying to use nutrition and exercise to build it up..... Any advice? What are your thoughts? Thanks in advance!!
