In that case I would imagine they'd suck for racing. Don't get me wrong, you could still beat them when you pretend like they just lost.
seriously though, I think any greyhound breed is known for beeing sleek, elegant, fairly beautiful (that part is highly suybjective of cousrse), calm, and good with people.
The toys of any breed tend to be more high strung - I'm not sure why, it is like they always have had too much espresso or something - they look like they are vibrating.
Also, the hunt-by-sight-and-ignore-all-else-whilst-bolting-after-said-prey thing I mention should still hold valid for the little ones too - it will just look funnier since squirrels aren't so small to them.
Whatever happened to the dalmations being the gay dog of choice? or is that just a lesbian thing now? (to be fair, the lesbians I know all have rotweillers - beautiful dogs)
