joe dog. Device with a dead axle that converts a single-axle tractor to a tandem-axle tractor. It hooks over the tractor's fifth wheel, replacing it with another for the semi to be hooked onto.reference 1

This is a specialized term exclusive to the drayage industry. The origins are unclear.  It may be that this dog is a considered a kind of latch.  Or it maybe that the joe dog acts as a kind of leash in pulling the second trailer behind.

Elusive as the origins are, it seems likely that the use of joe dogs led to double-bottoms or tandem trailers being referred to as “a set of pups.”
