let me chime in - agreed : ( a little bit late :-)
and to keep this discussion realistic .
I owned and breeded racing Slougis (arabian Greyhounds) for 25 years.
best time ever - of my 2 year old female was 32,12 sc. (500y racing track)
For fun in 1998 we took a young and obviously very fast female ISDS Border - 3 years , ( daily working with sheep) and took her to our 500y track
she ran 36, 78 sec - that was as fast as our second best Afghane .
so , not bad at all :-) isnĀ“t it ?
best
