When my friend Virginia saw our progress she offered to let us use her surcingle, which is a padded strap which goes all the way around the girth, and after our success with the saddlepad I couldn't say no! Starbuck accepted the surcingle surprisingly well and didn't seem to mind even when I tightened the girth a little, although she bucked and farted like a malfunctioning rocket as soon as she really started to move around with it.
Then I put on her rope halter (I wanted to see whether the other day she longed badly because of the cavesson) and took her out to the arena to longe a little. At first she didn't want to cooperate and kept turning to face me and stopping and after maybe about 20 minutes of this I kind of gave up and decided to work on leading a while. However, Javi, one of the owners of the stable saw that I was having trouble and came out to show me how it was done; in the end he got Starbuck to walk, trot and canter on the lunge line. So I need to work on following through in the future and remember to never let her win the patience game. It was a real treat to watch her from afar though and I was able to take some great photos :D
