===Porthos===
'''Porthos''' is Archer's dog. One of four males born in a litter of English [[Beagle]]s, Porthos and his brothers, Athos, Aramis and d'Artagnan, were named after characters from ''[[The Three Musketeers]]'' by [[Alexandre Dumas, père]]. He has been Archer's faithful companion since the age of six weeks, and has remained so for the duration of Archer's 10-year assignment as [[Starfleet ranks and insignia#Captain|captain]] of ''[[Enterprise (NX-01)|Enterprise]]''.

Porthos was portrayed by a male beagle named Prada in Season 1. Afterwards, he was played by a further two female beagles, Breezy and Windy, although the character of Porthos remained male.

Archer would occasionally leave Porthos in the care of [[Phlox (Star Trek)|Dr. Phlox]] when he was away or otherwise unavailable.

Archer cares very much for Porthos. In the [[Broken Bow (Star Trek: Enterprise)|pilot episode]], [[Travis Mayweather]] says Archer won't use the [[transporter (Star Trek)|transporter]] for himself and certainly not for his dog. In "[[A Night in Sickbay]]", Porthos nearly dies when he contracts a deadly [[pathogen]] on the [[Kreetassan]] homeworld, but is saved when Phlox [[organ transplant|transplants]] a gland from a [[chameleon]]-like creature.

In "[[Similitude (Star Trek: Enterprise)|Similitude]]", Archer explains in answer to the question "Can he do any tricks?" that "I haven't taught him any, mostly what he does is eat, sleep and not fetch." He also commented "there's nothing Porthos likes more than dinner time".

Although Porthos is not the first domesticated pet to be featured in a ''[[Star Trek]]'' series ([[Data (Star Trek)|Data]] owned a cat, [[Data (Star Trek)#Spot|Spot]], in ''[[Star Trek: The Next Generation]]'' and Captain Jean-Luc Picard owned a [[Pterois volitans|lionfish]] named Livingston), Porthos has the distinction of being the first pet to maintain an ongoing presence in the series, and even – as illustrated above – become the focus of an episode.

In the [[Mirror Universe (Star Trek)|Mirror Universe]] depicted in "[[In a Mirror, Darkly]]", Porthos is a [[Rottweiler]]. According to the episode's [[podcast]] on [[Star Trek#External links|Startrek.com]], the dog that portrayed the mirror Porthos was known on set as an even bigger "baby" than the dogs which have played the regular Porthos. Episode writer [[Mike Sussman (TV series writer/producer)|Mike Sussman]] noted that the animal was "The sweetest dog I have ever met."{{Citation needed|reason=Cite podcast or (more likely) Cite DVD commentary and provide timestamp so that editors can [[WP:VERIFY]] this|date=March 2022}}

In the episode "[[Acquisition (Star Trek: Enterprise)|Acquisition]]", Porthos was interrogated by a group of [[Ferengi]] pirates while the rest of the crew were incapacitated, but the aliens' [[universal translator]] could not decipher his barking. The pirates didn't know what to make of the dog, even speculating that he was perhaps food. They then decided they could sell him to a zoo.

[[Brannon Braga]]'s nephew had a dog named Porthos, which he thought was good name for a dog and took as inspiration for Archer's dog.<ref>{{Cite web|url=https://archive.org/details/star-trek-communicator-issue-135/page/n20/mode/1up?q=Porthos|title = Star Trek Communicator Issue 135|date = October 2001}}</ref>
