I would like some advise about whether or not I am not doing enough for my horse in the winter. He is an arab gelding 12yrs, due to the short days during the winter months I am unable to exercise him during the week at all, and if the weather is terrible during the weekend, we arent able to do much then either. He is turned out every day and in at night. He and getting to be over weight, although he doesnt get any hard feed. Our grass has held on. I am worried that he might get flounder. What can one do during these cold times?? Also he is a lazy little man and doesnt run arround the field much.
