I have always been told that the bigger the horse, the less likely he is to live to an old age. My 16.3hh, 22-year-old TB gelding is in very good health but, although he is doing well, I am getting paranoid about asking him to do ridden work. Every time he as much as coughs, trips or gets excited, I’m convinced he is going to go down with a heart attack. How can I get over this? It is ruining everything for both of us as he is not happy just standing out in the field and I am scared in case I cause him to die. I lost my 28-year-old, 14hh pony earlier in the year. He had adegenerative bone disease so I had plenty of warning and it was obvious when he had to be retired. What signs should I look for in my elderly, but apparently healthy, TB?
