I've had Bliss for almost a month now, and I've been having problems with her 'worried' nature as I am still gaining confidence myself. I wouldn't ride her anywhere outside the riding arena without another horse leading the way.
Then I read This is how we train a fearless trail horse! And I was like, okay let's try this! I rode her on the trails by herself, and she was amazing! Whenever she tensed, I got her into a faster gait, and it didn't take long for her to figure it out. She only spooked once throughout the whole ride, and I turned her in a couple circles towards the scary object and she was like "okay." XD We rode between trees, next to giant dirt piles, near a parked trailer, in a narrow fence opening, and we even crossed the scary bridge of certain death that caused her to bolt once! And for those of you who saw my other post about her not liking jumps that are new to her... she jumped a couple logs on the trail without even looking at them! YEEE!
Aaahh I am SO happy with her right now! I hope we keep improving like this!
