So I get that nature plays a part in dog behavior. However I genuinely do believe nurture plays a fucking huge part. Case in point, the Papillion.

The Papillion was literally bred for fuck all. They were meant to sit on people's laps and warm their hands.

Check this Papillion doing better than border collies at agility trials

Here is a pappillion jumping 16ft7in into a pool - for the record that would be like a labrador being able to dive about 30ft into water

Were pappillions bred as ratters, herders, or retrievers? No, they were never bred for these and are still not bred for them today. But look at them excel at these sports, outcompeting dogs that have been bred for centuries to do this shit.
