Alright thanks everyone! His weight is the best now that I've ever had him at. If I were to keep him on the TC Sr, how much weight of feed each meal would be ideal?
We do not know for sure he is cushinoid, its just been a thought of the vet because of his slightly longer/thicker coat that takes a little more to shed out. But at the same time, if he really is 24 maybe that is solely why??
I will look into Nutrena. Not sure if we have it local but I've heard about it and need to see if its around here.
Over the winter without much grass we do keep the big round bales of hay around.for the horses. Hunter just also gets alfalfa as a treat a few days a week, but it has greatly helped his weight and energy level.
