Has anyone had to deal with a headshaker? I am requesting any info good or bad after the vet was out today to my friends horse. When she started she was treated for a possable infection and over the past few months has gradually got worse. Vet is hoping to do an explanatory of Sarah's head to rule out various things, but has told my friend to prepare herself for the worst. He will only do this however if her insurance will pay for it. We would like to know what are the chances of putting this mare into foal if she is unable to ride her again. Any info on this subject would be most welcome.
