Yes. A good example of "artificial selection" according to Richard Dawkins.

Artificial selection (or selective breeding) describes intentional breeding for certain traits, or combination of traits.The term was utilized by Charles Darwin in contrast to natural selection, in which the differential reproduction of organisms with certain traits is attributed to improved survival or reproductive ability (“Darwinian fitness”). As opposed to artificial selection, in which humans favor specific traits, in natural selection the environment acts as a sieve through which only certain variations can pass.

I got into that discussion on another board some time ago with a guy who was insisting that the skeletal differences between HNS and HSS 'proved' they were different species. I asked one innocent question. "What skeletal differences are those? YOu mean like the differences between modern Watusi and Inuit?"
And the battle was on!
And if you want to send expendable politicians then we have a whole party full of them!
Please! Send them ALL! Send the lobbyists and lawyers, too!!!

This is tap-dancing around the term species to avoid having to use it. A circumlocutionary euphamism at best.According to the Kennel Club ALL dogs are the same species.
As if how they got there outweighed that fact of what they are now.artificial selection
