Hi and congratulations on getting your new pup
We got our second puppy in June and we let them meet each other in our back garden, took about 15 minutes for the puppy not to run away from our older boy. They have seperate toys because puppy teeth and adult teeth require different things but they do tend to share and swap. Each wants what the other has got.
Definitely get seperate feeding and water bowls, just so that you can teach the puppy from day one that it can't steal from the older one so to avoid food aggression issues. We always have 2 bowls of water down, but they do share now as they are more comfortable with each other. Plus we used raised bowls and my boys was too high for the pup.
The one piece of advice I would strongly reccommend purely from personal experience is try to leave them to sort things out vetween themselves as much as possible when it comes to play etc. Like me you have probably read this loads, but instict overcomes you to protect the baby from the older boistrous dog, and with you older still being a pup they will still be really playful. We felt like we were constantly telling our boy off for the first 2 days but then completely backed off and things improved dramatically on there own when we stepped back.
Don't expect things to settle over night, we found our boy was in a constant state of excitement and just wouldn't switch off for about 4 weeks. We started really worrying about him because he was so tired but would only sleep with one eye open when the pup did. Our pup has been with us for 3 months and I would only say things have drastically calmed down over the last 5 to 6 weeks.
Remember to spend good quality one to one time with your older dog & pup seperately.
Good luck, and enjoy
