Appropriate Animal Attire/Analysis

Normal Animals Wearing Clothes or Accessories
This is about animals wearing accessories and pieces of clothing. Only, they are not cartoonish animals. They still walk on four legs (unless they are a bird or another animal that is supposed to be bipedal), most don't talk, they eat from the floor, and most lack the opposing thumbs and manual dexterity that allow them to hold things.

Given the lack of proper clothing that animals can wear without feeling unconfortable, the amount of clothing they can wear usually doesn't exceed the accessory-wearing or half-dressed (shirt or other top but no pants or other bottom version) tiers.

Truth in Television: Some owners do give dogs clothes for them to wear, mostly for small dogs in winter. Also, working animals almost always wear special packs, vests, jackets, or blankets marking them as such.

General Examples of Accessories and Clothing Given to Normal Animals
These clothes and accessories are typically, stereotypically, or sometimes given to nomal animals and their fictional counterparts, the Nearly-Normal Animal, Talking Animal (whether speech-impaired or not), and Partially-Civilized Animal. Sometimes, these garments and accessories can show up in Civilized Animals, Funny Animals, and Petting Zoo People as well.

Reasons Normal Animals Are Given Clothes or Accessories in Media
The reasons to give animals such accessories (aside from the usual collar and tag for dogs and horseshoes and halter for horses) and partial clothing in media is to make them more unique. People would likely remember a puppy with a tophat instead of a simple puppy. It can also be used to mask the fact more than one dog is used for the same role in a live action show or movie. The audience would remember the accessory and overlook the fact this dog is slightly smaller or bigger depending on the scene.
