Dogs

Dogs are a species in Adventure Time.

Attributes
The dogs in this world for the most part have been shown to be a specific orange-colored breed of bulldog have many attributes akin to real dogs: they have increased senses such as sight and smells compared to humans and have shorter life spans due to living in "dog years". However beyond those, dogs have adapted and evolved to the circumstances of the world they now live in. They have become anthromorphic and gained the means of speech as well as the usage of tools and weaponry akin to humans prior.

While it is unknown if it specific, some dogs also have gained other, supernatural attributes beyond merely being dogs or anthromorphic dogs. These include various magical powers such as being able to change their size and mass, as well as communicate with one another in dreams.

Society
Though they appear to live in a society akin to many of the other creatures of this world, they have a preference to being companions towards other beings, in particular humans. The most notable dog was Jake, Finn's companion.

History
Some time before the series, they were at war with the Rainicorns for the Crystal Dimension, and lost, as mentioned in the episode "Her Parents."
