I agree, the dogs I keep I would describe as type 1, I’ve had both types and as much as the full on ones can be fun to watch it’s not so much fun carrying them off the field or burying them.
A clever dog with a big heart & a reasonable turn of pace ticks all the boxes for me, the best dogs I’ve seen run haven’t been out and out speed merchants they’ve just been fast enough & knew how to use it.
