for me, it's kinda hypocritical in a way.....i don't think that a pup should leave the mom/litter till at least 8 wks, and that would depend on the breed and individual pup (like mentioned above, smaller breeds, i think, should stay a little longer...and some pups just aren't ready to leave as soon as others in the litter)....however, i prefer to get my BC (and only the BC) pups at about 6 wks....the bond and partnership seems stronger between dog and person if they have those earlier wks, as well, but only if the person has the canine/puppy knowledge to get them thru what is critical during those last couple wks of litter time (does that make sense?)...this has, at least, been my experience and 2 other breeders that i have talked w/ have said/felt the same way.....(not saying it's 100%)
