Getting nervous around new horses is not a big deal. It happens all the time. But horses can totally tell when you're nervous. Totally. And when they know you're nervous, they'll take advantage. Trust me. I know it's hard, but just try to stay calm and relax. Tell yourself its just another horse. If you're not comfortable riding or even tacking up, and especially in the stall, just take them out and walk them around. Touch them, talk to them, just be around them. The more time you spend NOT working them, the more trust will build up and both you AND the horse will be more confident and comfortable with each other.....Does that make sense?
