Everyone always has their own opinion.
I disagree with the other posters who say you don’t need to get a halter on her. One of the first things TIP mustang trainers do is work toward haltering so they can then work on leading. I know you said you don’t like videos but there are some great videos of trainers haltering mustangs. I don’t think it’s about getting kicked, it’s more about having some control and teaching them that they can be with you and they aren’t going to get hurt.
Heck, I wish my BLM mustang was a little more skittish around people he thinks people ARE THE BEST and is a little too snuggly if you know what I mean.
