hi --- some horses do loose weight when in heavy training. worming is  always a good thing to do on a Greg basis. checking their teeth is also recommended every 6 months. some horses train better off the farm. you can always have a physic check your horse out . they can find problems out that are bothering the horse. hope this helps you.  thanks ED HESS
