Kim, I'm prepared to believe this puppy might have been doing a calming sniff. I can't say for sure either way. It was too long ago, I was not as experienced at the time, and I couldn't even see him that well in the dim behind the couch. I don't remember enough about his behaviour leading up to it. Maybe I didn't even see it.
Yes, it was long ago. And it's possible the sniff wasn't a calming signal too (although I "think" it might have been). I'm just addressing all possibilities. :-)

still think his behaviour was unusual, but I also believe much of his aggression that came about later in life was fear related.
It may very well have been unusual, although I"m sure at the time the pup found it quite appropriate. ;-) Too bad we can't get into their minds sometimes to see what wheels are really turning. The fact that you see a lot of aggression later in life that stemmed from fear, though, provides stronger support for what happened as a puppy. It seems to fit well with a typical fearful dog.

It's baffling because he had been socialised to kingdom come all through the socialisation window and beyond, and he had plenty of good experiences.
The reality is, socialization doesn't solve all problems. Dogs with genetic fear predispositions, or genetically reactive personalities, are sometimes predisposed to reacting to things that other, normal dogs are not. What might not be a life-altering thing for a lot of dogs, can be for another. Also, there is such a thing as too much socialization, if the puppy is not prepared and does not have adequate rest between social outings. A puppy that encounters stress may quickly develop chronic stress if not allowed to let social experiences sink in, and it can have a very detrimental effect on a puppy's wellbeing. Stress hormones stay in the body for days, up to a week, so if the pup is exposed to another stressful situation (and stress comes with the sheer fact of being a puppy and learning about the world), before the stress hormones could dissipate, it can easily build up until the dog is just flowing in stress hormones (I could use the real term, but sticking easy to understand words) and could affect the pup for a long time to come. It's one place where I do disagree with Dr. Dunbar regarding socialization. ;-) There is such thing as too little, but there is such a thing as too much as well, and pups can become overwhelmed at new experiences, even if they aren't inherently scary.
But the idea behind stress hormones and working with animals is another topic in and of itself, but a very fascinating one. It's why when I take Gaci out on outings right now (living in the country), to work amongst people, I give her at LEAST four days to allow that experience to settle and her body return to homeostasis before stressing the body again (as even in the slow work that we do, it still allows for the release of stress hormones, just a lot less).

It may just be that the other puppy had more complex problems and we did too many wrong things and not enough right things, but I for one will never know.
You will never know, and you shouldn't beat yourself up over it. Sometimes people can cause problems, yes, and in those cases it is important to learn and reflect, but sometimes, despite doing everything that is "right", some puppies still grow up to have problems as adults. Just like with people. It's just what makes dogs individuals, and their bodies and minds, and brains, are all different. Gaci is a case in point. Bred from very good stock, with known histories, and a prior litter to compare personalities to. What resulted in Gaci, is a dog whose mother died at birth, was raised part-time by a surrogate mother (who, between two litters, shared 13 puppies - for a small dog that is a very large number) in which the pups developed a severe respiratory infection due to the lack of colostrum, causing a lot of developmental stress, during a time when the brain was developing, and of course lastly, even though the lines were known, always lies a possibility for a genetic combination in which the right genes matched up to create a personality that was more sensitive to the environment that other dogs may be.
Getting a dog from birth to adulthood is so complex, so many factors weigh in - genetics, early learning, illness, environmental enrichment, exposure to various things, brain make-up, hormone make-up, stress that occurred, socialization, diet - all of these thigns, combined, are what make a dog what it is, and any of these things, when disrupted (even diet for a young pup!) can result in semi-permanent to permanent changes in an animal. Even fetal distress - if a dam (mother dog) experiences higher than normal stress levels during pregnancy, that can have an effect on the brain development of puppies a litter, and can predispose puppies to various issues, even if their genetics are otherwise normal. There is no guarantee when it comes to living beings, and contrary to the beliefs of some, not everything can be overcome by training and good leadership. Life just doesn't happen that way. Having grown up in a breeding family, I've learned just how important, through reading and first-hand experience, some of these factors can be.
