I have a regular 3 horse slant and Cody uses the back 2 stalls, although he can't lift his head up tall. I have to save up some $ to afford a newer 3 horse warmblood size. My pony is going to look tiny!
Oh, another I just remembered because I'm worming today is, the wormer doesn't come in 1500 lb. Size so I save what is left over from my other two regular size horses and add that to Cody's wormer!
