Do your horses feet that look like this.If so they have a serious balance problem.
The pic on left shows high on inside,the pic on right shows too small of shoes and under run heels.
I had a customer ask about hock injections as preventative maintenance. I was shocked too here that people are doing this. When it is so easy to keep your sound just by proper hoof balance. Why spend hundreds of dollars on injections when it can be fixed with proper shoeing.
Same horse balanced too it's natural bone structure. Using just bigger shoes on hind. I believe we can fix any lameness problems by balancing our horses too there natural bone structure.
