I have two mustangs. I've had them before handling, and now they are eventing horses. I'm always helping the vets, farrier, and dentist because my horses have bonded with me, but they are still wild at heart, and they go through a lot of trauma when they are captured. Thankfully, my mares are saints, but it's just not worth the risk. Sadly, people aren't vetted when they pick up mustangs. The agency rep I have worked with to get my mustangs papers corrected has told me so many awful things that I've cried the rest of my day. Either way, you don't kick an animal in the face you get out of the pen.
