I have a 21yr old QH gelding who is in excellent health. I still use him as my primary trail horse. Just this past month I have noticed his withers appear to be more prominent, as though he is starting to lose a bit of mass up top. His back along his spine still looks great.
He is on free choice hay, and gets 3/4 of a coffee can full of senior extruded feed once daily.
I was wondering if there was anything I could do pro-actively to help maintain his topline as he ages.
I board him, and generally am only able to get out 2x a week to see him.
Any tips or suggestions are much appreciated.
