Stock Animal Name

""If there must be a cat, do not, for the love of God, name it: Magnifi-cat or similar pun; Mr. Adjective-Anatomical-feature; with two or more words all starting with the same letter; or with any name plus the surname of the cat's owner.""

- How Not to Write A Novel

Sometimes it's just not worth making up original names for animals. These are names that have been used forever in real life for (usually domesticated) animals, and carry over well for animal characters in fiction. Sometimes its an obvious pun or description of the animal's appearance.

For dogs and cats it seems like a new "stock" name is "Mr." or "Mrs." something; Mr. Muggles (dog, Heroes), Mrs. Norris (cat, Harry Potter).

The bottom line is, if you want an original name for a character, don't use these ones. Note that no one ever uses these names in Real Life. (At least, not anymore.) They don't even show up in the lists of most popular pet names. But if you use the names correctly, people know immediately what kind of animal you mean.

Compare Species Surname.

Since this is pretty much a Universal Trope, don't bother listing specific examples. But if you know of an interesting subversion, it's probably worth adding.

Dogs

 * Spot, Rover, Patch(es), Fido, Rex, Buster, Sparky.
 * For more aggressive dogs, Spike, Wolf, Fang, Killer.
 * In the UK they're often named after boxers. Tyson in particular.
 * For Scottish Terriers: Scotty.
 * For German Shepherds: Ace.
 * For poodles: Fifi.
 * In Japan: Pochi.
 * The female leads in He Is My Master have a pet named Pochi, who the male lead assumes to be a dog. It's actually an alligator.
 * In France: Médor. (Pronounced May-Dohr)
 * In the Deep South, Beauregard, particularly in Looney Tunes cartoons.
 * Prince for big, nice-looking dogs.
 * Blue for hounds.

Cats

 * Sassy, Fluffy, Whiskers, Max.
 * In Japan: Tama. Usually (but not always) said "Tama" will be a calico.
 * For tomcats: Tom.

 * Fun fact: "Tibbles" is a corrupted version of "Tybalt", the name of the Prince of Cats in the Reynard the Fox stories. Tabby is a related word. (Now you know why Mercutio repeatedly calls Juliet's cousin Tybalt "prince of cats" in Romeo and Juliet.)
