Luna's favorite friend in the whole world is Clark. Clark is an almost 2 yo Border Collie mix. His wonderful parents adopted a 9 yo Border Collie/GSD mix called Turbo a month ago. Turbo is as sweet as pie, catches balls and runs around like a puppy, but is a very dominant female. Luna is also a pretty dominant female (to the point that most dogs immediatly lay down and roll onto their backs when they first meet), although she isn't snarky towards other dogs unless someone growls at her first. Turbo will get quite growly, but mainly when an unleashed dog runs up to her or if she doesn't get the first sniff.
Here's our conundrum. Luna and Clark have continued to have regular play-dates a couple of times a week, and we would love to get Turbo involved as well. My friends are also moving to a house that is literally right across the street from mine (I am already prepping myself for the amount of wine that will be consumed) in September, which means that chances are, we will all be outside at the same time, although neither of us have fenced yards, so all outings are on a leash.
My question is, what is the best way to introduce two dominant females? We will absolutely have them both on a short leash and under a lot of supervision, but I would hate for them to go at each other. If one of them starts growling or their hackles go up, should we separate them right away? Also, if the introduction goes poorly the first time, are we basically out of luck for future meetings? I would love some of your insight, because the safety of our dogs are first and foremost in all of our minds, and we want to make sure we introduce our companions in a safe and controlled way.
And just because they are so darn cute, here are Luna and Clark:
