Ok so my tennessee walker that I got a couple months ago I was told he was 18. Well the previous owner had his paperwork in another state. So today I get it and OMG he is 27 years old. Granted he seems to be in great condition he was severely obese and was put on a diet, and ridden etc and now is in great shape he is always the one who leads trail rides and we have to wait on all the younger horses.He loves it but now that I know his true age, What do I do now should he just be retired?or what I have never had a horse this old what should I look for?Thanks in advance
