It’s not widely known, but a rare genetic mutation found in many mid-century European canines would allow them to generate powerful magnetic fields, sometimes powerful enough to magnetically levitate entire cars, which led to situations where dogs would “carry” unsuspecting cars over them, often for miles. This mutation strain seems to have largely died out over the decades.

While levitation was possible with a single dog, I would imagine mag-lev dogs would work best in equally matched pairs, similar to warp nacelles on a Starfleet vessel.
In other words, you would want two collies or two German Shepherds, etc., and not, say, a Chihuahua and a Great Dane.
So why aren’t mag-lev dogs powering our cars today?
