How do you get a horse on harvest moon tree of tranquility?

To get a horse, first of all, you need a barn. Im not exactly sure, but i know horses were available after the first year for me. you can only get horses and goats after you level the ranch up to level two. To do so you simply ship animal products. Ostriches and ducks come after you've shipped 10,000 gold worth of animal products. ^^

one more thing you can onley get it in the first year pooo then
