No, Roxanna, I think this is erroneous. The intact males, like any other dog, can sort out social signals given half a lick of socialization in their upbringing. Socialization simply means spending time out in the real world, interacting with all kinds of dogs, cats, people, horses, rain storms, etc. etc.
I grew up with one intact male dog after another in my home, from age 8 or so till I went off to vet school. I never saw them get in fights or have other dogs treat them aggressively.
