What BBN said about it

Vera Bullock · Co-AnchorOn October sixteenth, twenty twenty-six, Smithsonian Magazine reported that small dogs tend to live longer than big dogs, and scientists say they may finally know why.

Dale Bearman · Chief Skeptic & ContributorLarger breeds like Great Danes seem to pick up changes to the chemical tags on their DNA faster than chihuahuas do.

Dale Bearman · Chief Skeptic & ContributorThose changes let jumping genes move around.

Vera Bullock · Co-AnchorJumping genes!

Vera Bullock · Co-AnchorWhich is why BBN is proud to open the Pet of the Day ceremony for the chihuahua, the small dog with the long game.

Dale Bearman · Chief Skeptic & ContributorGenes jumping around in the dark. Wonderful. First the genes, Vera, then the furniture.

Vera Bullock · Co-AnchorOur winner's official title is Duke of the Long Walk, Defender of the Sofa Cushion, and Quiet Champion of Molecular Stability.

Dale Bearman · Chief Skeptic & ContributorStats this season: nine thousand naps, zero jumping genes admitted, and one cardigan worn under protest.

Vera Bullock · Co-AnchorCardigan under protest. And the best part is that the study says it goes all the way down to the molecular level.

Dale Bearman · Chief Skeptic & ContributorThe Great Dane carries all that bigness, and the tags on his DNA just pile up. Poor giant.

Dale Bearman · Chief Skeptic & ContributorTiny, unbothered, and still here after the rest of us have panicked. You earned it, little one. I'm not crying, you are.
