> I don't think there's any reason to get a pure bred dog unless you want to show or breed it yourself

There is one other reason - working dogs. Livestock guardian for example is a job that's very poorly suited for mutts due to the genetic personality traits involved. An LGD with chasing, shepherding, or tracking instincts would be at best worthless, and at worst a danger to your animals.

Yes, but a working breed is vastly different to a domestic breed. Working dogs need to be intelligent, obedient, and free from health problems.
