I did a bit of GOC practise, Flippa helped, we ride in Track 1 and 2 with Garbo on Track 1 and it kept him interested. By the end he was really playing with the bit instead of just opening his mouth.
Then we went for a hack as a reward, along the farm road internally, past dogs and houses, then onto the road, along the road (3 cars passed) and back in the other driveway entrance in a big circle.
Flippa and Garbo get on really well there is no squabbling on Garbo's behalf. Rare!
