Thanks everybody for your help ! 😀
When clipping always make sure to go with the hair 💖☘️🌈💖
First try to watch an experienced person clip, ask questions, and make sure you have a machine with sharp blades. Also make sure your horse is not afraid of the clipping machine, or else they will move or even kick. In that case, have someone help you hold the horse or give it a light sedation to protect both you and the horse from getting hurt by accident!
There are a lot of great videos on YouTube on how to clip!
