He look's nice! What is he? Appendix?
I know what you are going threw.It is hard work.When I got my arab/saddle bred he had no muscle was way under weight.Now he is toned but is be coming fatty lol.I broke my arm and can't ride so he is slowly losing it ugg. My OTTB I just got also has no muscle.He gets so sweaty even when it's in the 30's.But he looks great!
