My latest girl joined us in July. She is my second import in two years so I kind of knew what to expect :)
I only have one other dog and I introduced them straight away in the garden when we got home with the new girl.
I would just slot her in your routine like you live and she will soon be part of it, it is amazing how quickly they do become "yours".
I really do not see reason why you should not walk her for such a long time.
You would be missing out on socialization and I have found it a good bonding exercise to take them out of their home environment as they will naturally rely on you being the most familiar object there.
My newest girl grew up with her brother and pack of other older dogs,she was little lost when she moved to live with us but soon settled.
It definitely took her little longer to settle compared to my first girl who grew up in a family environment and was not relying on "other dogs to tell her what to do".
I can't wait to have a puppy from puppy as I do miss having the opportunity to work on a baby puppy, it is different to being given 10 month old that has been taught by somebody else.
My younger girl did not have much work done with her, just socialisation& being used to being handeled etc....
She did not even know how to sit when she arrived :) but that was done on purpose and I actually preferred it this way as I now have a empty canvas and I could start training her like I want to train her from the start.
Good luck!
