Circle game with a purpose

I found last night that Tia needs a reason to circle... after struggling yet again to get 1 nice lap at trot we went off to play with other things. When I sent her to the barrels she just put her nose on them and looked at me, with a question, so I sent her off in the opposite direction and she was more than happy to jump over!!! light bulb moment... give the games a purpose!
When I asked Tia to put her foot on the green turtle again she was very hesitant, but eventually she did manage to touch it with her foot, without going introverted, so I was happy with that, gave her a treat and we went off to play with something else.
I spoke to Tracey and she confirmed that once she knew what was required off her Tia then became lbi and started "asking why should I?" Nice to have everything I thought confirmed.
We put Tia in with Bonny last night and as expected Tia is Boss Hoss! Rocky soon calmed down without her and Bella took over as leader of their herd of two.
