I think its great that you want to spend time with your horse and bond. It's an important part of horse ownership. The reason I think you may be giving horse people the vibe of needing a trainer is because sometimes horses can be viewed as loving, and majestic and caring. They can be, but usually they just need leadership. A horse kicking out when getting their feet done is actually pretty dangerous for someone who hasnt been around them a lot lately. I had taken 10 years off riding, and I had to start from the ground up again. It does make you a beginner again. I forgot terminology, fitting equipment, and I was intimidated at first.
I also got a trainer. To help both me and my horse. They sense if your tense or unsure, and they WILL take advantage of you. It can be extremely dangerous. We aren't trying to belittle your love or knowledge, we just all know better. We are just trying to help.
