Dog's fashion is a popular style or practice, especially in canine clothing and accessories. Dog fashion is a distinctive trend of the style in which people dress their canine companions. This trend dates back to the Egyptian pre-dynastic period and has since expanded due to increased consumer capitalism.

Dog clothes are available in various price ranges, from inexpensive to high-end designer styles. Typically toy and small breed dogs, such as Chihuahuas and Yorkshire Terriers, are dressed in dog clothes, although even large breeds like Golden Retrievers can wear clothes, too.

Cat coats, collars, cute sweaters, shirts, stylish dresses, and booties are some of the items people purchase to adorn their cats with style.

Humans typically have deep attachments to their pet because pets are adept at fulfilling emotionally supportive roles in people's lives which results in high levels of attachment.
