A poodle and a wolf can reproduce. Does the fact that poodle-wolf hybrids exist mean that the differences between a poodle and a wolf are just socially constructed?
No. Comparing genetic variation between humans produced by evolution with the relationship betweens dog breeds or species similar to dogs - is not a point about human 'races' - it's just gibberish disguised as science, AKA 'race science'. It's pretty telling, you spend more time talking about dogs than about human genetics, as if they were analogous.

I don't think that one breed is superior to another, but that doesn't mean I would charge poodles with taking down elk, or leave my kid alone with a wolf.
Yes, except if you were really familar with the science behind humans and human evolution rather than simply borrowing phrases, and crafting false analogies to trick then you would know that human behaviour is much more complex than wolf behaviour or dog behaviour and is driven by a more complex system (or brain).
The human brain and thousands of years of social culture (environment) mean that humans are far from simple in their behaviour or thought processess - we have a lot to consider, not just unseen genetic guidelines but complex emotion (something dogs lack, they are capable of simple emotion only), philosophy, religion, personal relationships - our upbringing etc.
Species without complex thought processes (brains and consciousness) usually operate on the basis of pre-programmed behavioural responses (like genetic 'instinct') to situations, but some also have a capacity for learned behaviour. These genetic guidelines may be quite broad but the point is their behaviour is not the result of critical thinking. A wolf has no complex conception of itself as an individual or of 'wolf-kind', or of what human children are.
In your analogy you liken humans to dogs (warning sign #1 Dogs are vastly different to humans, less complex) - suggesting that although you don't believe in superior 'races' you still wouldn't trust certain (human) races, expecting they would behave in a pre-defined way or share a common disposition (like dog breeds do).
This ignores the fact that genetic similarities may be quite small between individuals - so even though we both share the genes that lead to a particular skin colour - the rest of our genetic history may be very different - as undoubtedly with all the environmental factors i mentioned earlier (upbringing etc.) genetic similiarities become even less useful as a guide to how similar individual humans will actually be as people. Indeed, although individuals who share a particular gene or group of genes in common may share other genes too - this does not have to be the case (unless they're related!). And as genes like those that relate to skin colour are not bundled with 'personality' or 'behaviour' genes, the idea of 'racial' disposition is ridiculous.
In short, there is no scientific basis whatsoever to suggest that people who have the same skin colour would have the same disposition, personality, behavioural traits etc.

They all define groups that share physical and behavioral differences, but can reproduce.
You're talking about dogs here, as people have mentioned many dog 'subspecies' are the result of human manipulation - not evolution. Maybe if someone took control of all human breeding globally and spent hundreds or thousands of years breeding humans who shared particular genes together to make 'guard humans' then you could talk of human subspecies who shared common behaviours. But even then you'd be ignoring the fact humans (with our big brains!) are less the product of genetic programming than simple species like dogs.

Just to re-iterate, if this was ever to happen and was based on real science and not the ideology of racism that dog-breed lover is talking about, then i highly doubt these subspecies would be drawn on the basis of skin colour (which i assume is what dog lover would want). Indeed the only reason why race has been defined by humans in that way is because we can't see most other genetic differences in our outward appearance. But that doesn't change the fact that skin colour has very little to do with genetic groupings.
