hey, i know all about what they say, and we did the same thing, introduced them on neutral territory, we still give Lucius his props as the alpha dog by feeding him first, greeting him first etc. I am just giving you a heads up that even when you do everything right and even when it ends up fine in the end, you are likely in for a period of adjustment when the older dog's feelings are hurt for a little while. Lucius is the gentlest ball of fur on the planet and LOVES other dogs, and i have three kids and he is great with everyone and everything. but still the first time i heard him take off at top speed after Chanel, growling as if he would maul her to bits, i was taken aback! he had never growled hardly in his life, but he sounded vicious and i let it go on because i realized in watching them that she NEVER once yelped or squealed, so he never hurt her despite the snarling, and that when she raced under a chair that he can't fit under, he would bark for her to come out and when he caught her out in the open, she immediately flopped to her back and showed her belly. so she knew the rules and she knew what was going on and that he was trying to let her know who was TOP DOG. i am just saying be prepared for it because it might be a bit more complicated than you expect. oh and also be prepared for each of them to be obsessed with the other's food, thinking it's WAY better than their's.
