I have had him for around 3 years now I think. He has been healthy. The only non-routine vet visit was because of a minor injury to his suspensory ligament last winter. No colic or anything that would be related to weight loss. Normally his weight fluctuates, but not this fast and not to this extreme and it is usually related to changes in hay (when I get the new hay in), season changes, or when I fence off the "pasture" in the fall. He doesn't crib but he is a wood chewer. Maybe its related to that?
I was thinking of getting some senior grain tomorrow. Any brand recommendations? I think my feed store has triple crown, Purina, and LMF. Or any other feed (with it or something that would be better)? How much should I feed?
Unfortunately I know my vet doesn't take payments. They recommend the "Care Credit" card but I don't have any credit so that's out of the question. I would have to come up with the full amount or figure something out with my parents.
