  description: The Dog API (dog.ceo) is the internet's largest collection of open-source dog pictures, exposing over 20,000 dog images accessible by more than 120 breeds. The API is free, requires no authentication, and returns JSON. An optional `alt` variant returns image URLs paired with descriptive alt text for accessibility. The canonical implementation is the open-source PHP Symfony project at github.com/ElliottLandsborough/dog-ceo-api, licensed MIT.
