stumbling for 5 to 6 strides

Question
Hello Lisa. May i know why few horses stumble for every 5 to 6 strides? especially stumbling outer leg. What are they lacking? How should the rider stay balanced on them?

Answer
Stumbling its not a normal part of a horse moving forward.  It can be caused by hooves that are to long, physical injury, too large a rider, there are many possible causes.  If a horse stumbles often, it should be checked by a vet and not ridden until it is cleared for that by a vet.
