Need to lengthen stride
I have a friend that has a mare that a cross of something between a qh and welch origin. She has the pony mane & tail, and qh build, but another cross of pony might be in the mix.
She is approx. 14 hands tall.
When ridden, she will move out okay, but then kinda goes in to a waddle stride kind of like a pony stride. Short and choppy. At a lope she is great, at a trot she is okay. Sometimes it is like she switches between the pony stride and a regular stride.
What are some excersices that could be done to get the horse to lengthen their stride for a smoother ride?
