Well, a little dun filly came up for sale right by me and I went and checked her out tonight, but it was dark, and being short notice she was very dirty from our recent rain. I really like her temperament and coloring, but am very worried about her conformation. I'm not looking for something to take to high-end showing or anything like that, but would like a horse that isn't going to come up lame because of any issues. She's slightly cow-hocked in the back and has from what I can tell a low tail set. I'm going to see her again tomorrow all cleaned up and in the daylight this time, but I wanted the owner to be aware that I am very interested because she is what I'm looking for. She's definitely more up to weight than in these pictures that the owner had, and her neck doesn't look as scrawny as it was. Is it possible with some good muscling under her rear that her tail won't be sitting so low? What do you guys think??
