Dogs

Dogs are members of the Canidae family of the order Carnivora. The term is used for both feral and pet varieties. The dog may have been the first animal to be domesticated, and has been the most widely kept working, hunting, and companion animal in human history.

In the TV series Star Trek: Enterprise, the character of Jonathan Archer owns a pet Beagle named Porthos whom he keeps in his quarters aboard the Enterprise NX-01. This is the only instance where an Earth animal was ever allowed to live on board a starship. In the alternate timeline of the 2009 Star Trek movie, engineer Montgomery Scott confesses to doing an experiment on teleportation on the prized Beagle that belonged to that reality's Admiral Archer. Unable to retrieve the animal, Scotty was punished and sent to a research station on the frigid world of Delta Vega.

Dogs are sometimes victims of scientific experimentation or exposure to extraterrestrial influences. In the 1992 movie Alien³, a dog becomes a host for an alien symbiont and hatches a xenomorph alien that possessed some physical characteristics to a dog.

In the 1996 comedy/horror film Killer Tongue, radiation from a meteor mutates two poodles owned by a woman named Candy into drag queens. This is not the only instance in which poodles are biochemically altered in such a fasion. In the 2003 film The Hulk, scientist Doctor David Banner uses gamma radiation to increase the size and strength of his dogs.
