The hunting breeds are always focused.
I guess my wording can be confusing at times. This relates to what I've seen personally in my local dog park and isn't a rule and should probably have read, 'The hunting breeds, I've seen, are always focused.'
But for me, I would rather work with a dog that will independantly 'hunt' little critters/birds than one that just walks/runs along. You know they have something within them in which to work with. The only exception would be if the dog grew up with other pets thats similar to what you want to hunt. For instance, abird dog breedthat grew up with birds (paraket, parrots, etc.) or a squirrel dog breed that grew up with rabbits, hamsters, etc.
