Any new products out there suitable to race on that good for a horse who trots like a cat with 3 legs and usually warms out of it after 10-15mins but when it comes to hopple time it paces like nothing is wrong? She seemed fine winning her first workout but with going quicker showing signs of getting worse on her trot/ jog days. Am getting her gold injection on wednesday but am keen to hear if there is a better alternative/cheaper opition other than getting key to my gun cabinet out.
