I worked with Vega for a bit today. I used my parelli halter and lead and there was such an improvement! Whenever she'd prance, i would do a quick jerk on the lead and send her backwards. I did this everytime she acted out and after a few times, i only had to lightly pull on the lead and she'd walk back. I let her think and digest what happened, she'd lick her lips and we'd continue. She even stopped herself from prancing a few times. And she only bucked once and i did the same thing!
Next i decided to lunge her (because she's ignore my voice and just canter off). Anytime i asked her to trot and she broke into a canter, i did the same thing as i did when she was prancing. After a while, she would just trot around. She did speed up her trot, but with the slightest pressure on the lead, she'd do a more collected trot. I did it in both directions and she did great! I'm so proud of her!
I'll definitely be going up there everyday and working with her until she'll just walk calmly next to me.
Thank you so much for everyone's input! It's really helped me out a lot!
