I'm not dismissing herding behaviour. It is a thing. But genetics is simply not a good explanation for the story here. Here we have two dogs of the same breed (Arthur and Lenny). One lets their owner swim freely the other doesn't. The difference here is not genetics (they are the same berad), this in my opinion is a personality difference between the two dogs.
Which is why I'm starting my comment with "Idk if the "herding behaviour" is a useful way to think of this." Calling it "herding behaviour" doesn't explain the difference between the two labradors.

So lovely. Would you say that to my face closewith? I was nothing but polite to you and everyone else. I'm a human here you know. Can you treat me like one?
I do not claim any such thing. Simply that the difference in behaviour between two dogs of the same breed cannot be explained with genetics. Lenny and Arthur share a genetic background. They do not share the behaviour. There is some other difference between Lenny and Arthur (or between the two swimmers!) which drives the difference in the observed behaviours.
I'm not saying genetics is not a thing. It is simply not the right lens to inspect this situation here.
> And it is, indeed, peak HN arrogance to make that assumption.
Which I'm not making. In any of my comments. So we are good then. :)
