We are all entitled to our own opinions. I have been dealing with horses for 57 years, including several years with racehorses, pleasure horses, field hunters, and show horses who were not mine. I have also worked in the breeding shed and done field breeding (not much intervention needed there!) so I have a wider set of experiences than many others who have only worked with their own horses. And I still have things to learn and questions to ask. Since I cannot know what experience level posters have, I would not ever suggest anything that could be dangerous for them or their horses. At least, I hope I would not.
It is never the horse's fault
