The position and treatment of animals in Buddhism is important for the light it sheds on Buddhists' perception of their own relation to the natural world, on Buddhist humanitarian concerns in general, and on the relationship between Buddhist theory and Buddhist practice.

Animals have always been regarded in Buddhist thought as sentient beings, different in their intellectual ability than humans but no less capable of feeling suffering. Furthermore, animals possess Buddha nature (according to the Mahāyāna school) and therefore an equal potential to become enlightened. Moreover, the doctrine of rebirth held that any human could be reborn as an animal, and any animal could be reborn as a human. An animal might be a reborn dead relative, and anybody who looked far enough back through his or her infinite series of lives would eventually perceive every animal to be a distant relative. The Buddha expounded that sentient beings currently living in the animal realm have been our mothers, brothers, sisters, fathers, children, friends in past rebirths. One could not, therefore, make a hard distinction between moral rules applicable to animals and those applicable to humans; ultimately humans and animals were part of a single family. They are all interconnected.
