That is very exciting! I can't wait to see pics.
I have big dogs as well (Boxers) and we slowly introduced them one at a time. Our big dogs are getting old so they don't romp around too much any more. They are best friends now and the big dogs are very paternal with our Yorkie (max). Since Max was a little guy, he was always liked by other dogs and I think it is because he was so well socialized. I am sure it will be the same for your new pup.
Good luch with everything and WELCOME!
