Porthos was Captain Jonathan Archer's pet Beagle. (ENT: "Broken Bow") One of four puppies in a litter, Porthos and his brothers were named after the main four musketeers from the Alexandre Dumas novel The Three Musketeers: Porthos, Athos, Aramis and D'Artagnan. Porthos and his brothers were born to a female dog owned by the mother of one of Archer's ex-girlfriends. Archer was crazy about the dog and was the first person she called after the dog got pregnant. (ENT: "A Night in Sickbay", "These Are the Voyages...")
