LOL, here is a real blast from the past...
The first guy is a youngster, believe he was a 2 year old there but may have been 3, and to me he is in lovely condition. A growing youngster well covered, but just showing a little rib there, but shiny coat, everything about him just looks great.
The second, 17 year old mare, not long weaned from feeding two foals, and in poor poor condition, although her ribs look covered, if you actually touched her you would feel every one of them, see the angles on her butt there and her lack of shine?
Same mare 1 year later, heavy in foal but looking good I think, not carrying much weight herself, but putting everything into her foal.
This is why she is now retired, she puts everything and some more into her babies, and although she loves being a Mom, time for her just to chill out
