I have always let my dogs interact, and it doesn't affect anything.

Dogs are smarter than people realize (and humans are dumber than we realize )

I have had many females that could be in "groups" ... 3 on the couch ... with 1 male.
(Every so often, I have dogs that just absolutely won't get along with anything, and they are ALWAYS stupid dogs, and never my best.)

Never tried to put males together, as that just does not work, except in 1 instance with Silverback and Phoenix.

Phoenix was an elderly dog, and I brought him in during his last years, and Silverback was my favorite and therefore my house dog. Phoenix was actually the trouble maker, growling at Silverback constantly, whereas The Gorilla ignored Phoenix. At first, Phoenix would be in a crate, with Silverback out with his "harem." Then, I would rotate Phoenix and put Silverback in a crate. Phoenix would always growl at Silverback.

Over time, they got used to each other, and Phoenix stopped growling at some point ... and was so enfeebled I don't think Silverback took him seriously. I had 50 acres and would always let the 4 go out (3 bitches, 1 male) and then let the odd male out by himself. Eventually I let them all out together ... and they didn't even notice the difference. They had gotten used to each other.

Phoenix was deaf by this point, and slow. He would just kinda wander around, and I would waive him in with hand-signals and he would come back. Silverback was such a good dog, in so many ways, he began to care for Phoenix. He would clean his ears for him.

All this from a dog that could kill another dog quicker than any dog I've ever seen, except Stormbringer.

PS: Even with all that socialization, if you faced Silverback in the pit with a strange male, he would be over there killing it as quick as possible. You know the difference between a friend you're familiar with, and an enemy looking at you with hate, and your dog does too. I mean, just think about it: if your dog knows you, and is happy to see you, that doesn't mean he won't attack some stranger walking into the house

Again, dogs are not stupid. They recognize and can differentiate between other dogs, and their body language, same as they can recognize who's their owner and who's a stranger.
