I really think it varies from dog to dog and also breed to breed. A golden retriever and collie both tend to be less territorial breeds so more likely that they will easily co-exist with either sex and do good. I think shepherds tend to be more territorial and so often do best with male/female. These are generalizations of course and there is never sure-all way it will go. My two male collies lived in perfect harmony. Tasha and Tommy do as well but Tasha is more aggressive and Tommy extremely laid back and perfectly happy to accept his place in the pack.

I'm not really sure how huskies tend to be, but I think I've read in a few places of female/female being problematic sometimes. I'd guess male/female would do best but I'd research more on the breed before making an actual informed recommendation.

One of the better dog breed books I've looked at that gauge each breed's (mainly AKC breeds) tendencies is called 'The Right Dog for You' by Daniel Tortora. It gives a scales for each breed on their territoriality, obedience trainability, good with kids, good with strangers, if they are good guard or watch dogs, etc. It even gives a different rating for puppymill types of the breed. I've found it to be pretty accurate.

Here are the scales it gives for Siberian Husky (again these are generalized and individuals can differ of course )

Indoor activity: very high
Outdoor activity: very high
Vigor: medium
Behavioral constancy: high
Dominance to strange dogs: medium
Dominance to familiar people: medium to low
Territoriality: low
Emotional stability: high
Sociability within family: very high
Sociability with children: very high
Sociability with strangers: very high
Learning rate: high
Learning obedience: low
Learning problem solving: very high
Watchdog ability: medium
Guard dog ability: low

Btw if anyone is interested in what it lists for other breeds I'd be happy to share
