Less sensitive to correction should be part of Daisy's name.
I reeeeally think our dogs are related... but if so, I will give you the good news that this hardheadedness eases up as she ages.It's kind of a weird combo, but mine would completely ignore physical pain if she was in drive of some sort, yet is very soft emotionally. When she was about 4 - 5 months old she discovered cactus - would poke it with her nose and of course it would poke her back. She'd bark at it and paw slap it, and of course it would poke her again. She repeated this a few times a month for several months before she left cactus alone. So yes, hard headed and impervious to pain. But if I'm upset about something (nothing to do with her), she gets very quiet and just watches me or puts her head on my knee.
