It is a very rare situation, where I don't have both of mine together.
My Male Sneakers, doesn't like 80% of the dogs he meets, and is suspicious of the other 20%.
My Female Becca is just the opposite, save she likes ALL the other dogs, and meets them with vigorous tail wagging and friendly posture.
If I see a situation coming, when mine are going to have to "meet" another/others, I shorten up my Male's leash, and let the Female take the point. I can tell my Male doesn't like that, first I think because it puts "HIS" little puppy beyond his immediate protection, and that position is supposed to be his anyway.
I rarely allow either of mine to get close enough to another dog, save to maybe touch noses, and always evaluate the ability of the other person to control their animal. I've seen some rather diminutive people, attempting to handle rather large dogs, and I frequently just avoid them if possible.
I am highly protective of my two, don't approach socialization as most others here do, and don't mind it at all if I see someone scoop up theirs as we approach. I often thank that person for that, and have gotten many curious looks.
