Trax jumped 20" until he was 4 1/2 years old. It was always funny to see people's heads turn when the gate steward would call out for a Sheltie in the 20" class.
I got his challenge measurement after that and he's been jumping 16" ever since. But I'd go back to 20" if we had to. He jumps it with no problem whatsoever.
What was he measured at when he was jumping 20"?
