It was modified by Pain using the Amplification Summoning Technique, so that it can split apart, when struck, into individual dogs that can then merge back together. It gains additional heads every time it splits in this way, and each duplicated head carries the Chakra Receiver and the Rinnegan like the original. According to Nagato, the only way it can be defeated is by defeating its original summoner. In the anime, this summon is seen at different sizes, ranging from several stories tall to just tall enough to fit underneath trees.
This dog is also physically strong and resilient, since it broke through an ANBU Captain's Earth Release: Sticky Earth Drop technique, and another's Lightning Release: Sixteen Pillar Bind, and received no more than minor burns from Fire Release: Fired Pottery Technique despite having its legs cut off by the Wind Release: Wind Cutter Technique. Even a usually devastating attack, such as the Wind Release: Rasenshuriken couldn't kill it easily, as the dog merely continued to multiply.

It was summoned again during his attack on Konoha, where it fought against Gamaken, Gamabunta, and Gamahiro. They were unable to prevent it from splitting and it only disappeared once Naruto defeated the Animal Path.
Shinobi World War Arc
It was summoned again during Nagato's and Itachi Uchiha's fight with Naruto Uzumaki and Killer B. Naruto attacks it only for Nagato to remind him that it can't be beaten directly. Later, after Itachi was freed from Kabuto's control with the use of a powerful genjutsu and his crow, he uses Amaterasu on the dog, incapacitating it.
- This animal summoning has the qualities of two Greek Mythological creatures, the Hydra (its abilities to produce more heads) and the Cerberus (its appearance of a dog with several heads).
