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!
