But again, why NOT have a pup exposed to all of the house sounds if you are going to have it in the house? I personally think that the more things a pup is exposed to early in life the better. If you don't think that makes a difference, then don't worry about it.
I guess I'm not sure why this is really an issue. I am going to have my dogs in my home, so why have them raised in a home from day 1?
It's not that there's any real reason NOT to do it. Myself and a few others are just saying that it makes little difference, in the end. In other words, there's no reason TO do it, either. We're all just saying that a stable dog won't flip if it wasn't exposed to a vacuum from birth onwards, and sees one at 8 weeks. That's all. So for me, finding a breeder that is producing the kind of dog I want is more important than house/kennel/chain spot, as long as the dogs are well-cared for.
I dunno, my Cardi was raised in a home and VERY well socialized. And yep, she has a great temp, is a great performance prospect, and a god awful housepet. Too much energy, too much drive, no offswitch. Luckily I don't care, LOL, and I think it's kind of funny. Her breeder did some things early on that I SUPER appreciate, like encouraging her to retrieve and nurturing her prey drive, that I do feel helped shape her into a better performance dog.
BUT, I know lots of breeders of working dogs (Mals, Dutchies, GSDs, the like) that do all those things, and the pups live in kennels. Some people involved in bite sports will actually tell you that kennels are better for pups, because too many house rules will squash drive (not saying I agree, just pointing out a their way of thinking).
I mean, you have to understand that Lindsey and I have the shared experience of having a woman with a skittish rescue Dobe watch Traveler playing as a 9 week old puppy. She remarked, "What a confident little puppy! He must have been socialized early." And both of us just sat there and thought, "He didn't leave the ranch he was born on until he flew across the world to come here..." Watching a kennel raised pup from parents that are not pets but dogs that have to work to eat (and will be leaving if they don't work) adapt to life as a housepet and sport dog with no problem has strongly influenced both our opinions (if I may speak for you, Linds.
)
Like I said, no one's saying there's any reason NOT to raise them in the house, just that we've not found any particular benefit either.
