I'm sure that Torrin on the forum here will tell you about a similar happening when Clunie, Fynn our Lurcher, Cally our Rotti cross and Cullen all met up in a large field.
Cullen is 34"at the shoulder whilst Clunie is 29", yet she managed to bring him down as Cullen was daring to chase Fynn! We'd a great couple of meetings in Blair, just watching the dogs run and noting how our madam who was only just the youngest thought that she was the boss.

It was just lovely watching the derhounds play, chase and run and noticing how differently Fynn(deerhound/greyhound)ran to them.

Poor Cally tried to join in but ended up just watching the speed merchants.
