These photos were taken two weeks apart.  I know the difference is subtle, but I think you can see Ripple’s topline has relaxed quite abit and the angle of the hip has changed.  The illusion is that he has filled out in the rump area.  What is really happening is that the tightness in the hamstrings is lessening, allowing the hip to relax into a more normal position.  Some of this relaxation is a product of time and lessening anxiety about his new place and herd, but some of it is diet, acupressure, massage  and movement.  Nice start.  Relaxation is the start of everything else.  I like this horse!
