Dog yōkai

Inu yōkai, or dog demons in the English dub, are anthropomorphic demons with characteristics of dogs. All known dog demons are incredibly powerful. Although they spend most of their time in human-like forms, they have the ability to revert to their true forms, those of giant dogs.

Abilities
Inu yōkai are one of the most powerful species of yōkai seen in the series. They posses a wide array of powers and abilities and all pure blooded dog yōkai shown are Daiyōkai, the strongest type of demon there is. Inuyasha is half-human, but even he possesses great strength beyond those of average yōkai. Inu Yōkai's most prominent skill is their ability to take on human forms which allows for easier interaction with humans and smaller demons. They have incredibly long lifespans and are immune to all forms of diseases and strong purification powers which may be fatal to regular demons. They can master a variety of magical and mystical abilities, such as creating acid, generating lightning, flight, teleportation, psychic powers and strong yōki. Like regular dogs, they have heightened senses, most notably scent. They also have super human strength, speed, endurance and reflexes which make them excellent fighters. Powerful swords can also be forged from their fangs which posses incredible power beyond those of any ordinary blade, Sesshōmaru has also shown that he has the ability to create a powerful blade from his own body. Author Rumiko Takahashi stated in an interview that Inuyasha, Sesshōmaru, their father and Sesshōmaru's mother are yōkai. The Akita breed originated from Japan, and is known to be one of the oldest of the native dogs in Japanese history.
