Wagtail
Horse servant
Does that also make riding horses mistreatment? What about shoeing them and keeping them in stables. None of these things are natural for horses.
If we were feeding buckets of the stuff I'd think you had a point, but we are talking very small amounts here - no more than he probably gets hoovering up insects in the grass. Next time I see my old loan horse aged 30, I will check with him how he has coped with being on joint suppliments for the past 12 years. Last I heard he was doing just fine!
Yes, many people think so and who are we to argue? We all have our boundaries. Why you think that I should feed something to a horse that I believe maybe harmful to them just because I am a YO is beyond me. It is like making someone who thinks shoeing horses is cruel, shoe someone's horse. Do what you want but don't try to tell me what I should or shouldn't do in terms of yard rules. All my liveries (including the one who used to feed the supplement that I banned) are of like mind. She didn't know the supplement contained meat products until I told her and was actually very grateful that I pointed it out. After that, I had it written into the agreement that everyone signs. So everyone is happy.
