Oh, my! We ALWAYS call Rien a lab trapped in a Mally body. He fetches, swims (only to chase geese), and has a better recall than my shepherd mix (knock on wood).
Rien doesn't pull much, either. But sometimes he gets to running too fast and hits the end before I can think to yell "whoa" or whistle or what have you. Not to mention we had a super bad expierience with my uncle and cousin's lab when I was like 6... She wrapped a flexi around my legs a few times and then snapped it and ran into the middle of the road. Thankfully it was one of those small Minnesotan towns, but I still have the burn scars. I just feel safer with the all tapes, though I'm sure something could go wrong with them too.
