Hi. I found the following link useful
http://www.dogbreedinfo.com/articles/adultdognewpuppy.htmMy pup is now 6 months, my girl 9 yrs. I sleep downstairs (don't ask ;) so no issues with where they sleep - with me. Pup has a small crate/den within a very large crate that acts as a playpen. I did, at first, extend this at times with wire mesh panels to give my girl a break and him lots of room to play in the day. I also got an Adaptil diffuser, don't know if it helped but it's been great my older girl has a new lease of life, loves playing with him and keeps him in order too - she does know I'll 'protect' her from him if he gets too boisterous and I separate when feeding, especially high value bones (I raw feed)
Another decent article despite being wiki is
http://m.wikihow.com/Introduce-a-New-Dog-to-Your-House-and-Other-DogsMy girl is 21kg pup will make about 8/9 kg She is very gentle with him, though if you saw her with his head in her mouth... & the noise they make you'd think they were killing each other.
I hope you have lots of fun with them both.
