Quadruped
A quadruped was a four-legged animal.

Doctor Phlox professed to Jonathan Archer that he had underestimated Archer's attachment to his "subservient quadruped". () Later, when the command area was temporarily placed at the catwalk,  informed the captain that "the entire crew's accounted for including one quadruped" – his Beagle, Porthos. ()

In his "Ode to Spot" in 2369, Data noted that Spot was an "endothermic quadruped, carnivorous by nature." ()

The Lan'Tuana sector was inhabited by quadrupeds. ()
