Ninken

Overview
Ninken are essentially dogs that have heightened senses and abilities, and as such, are able to work alongside shinobi. Although the dogs belonging to the members of the Inuzuka clan are ninken, the phrase is usually used in reference to the pack of eight ninken summoned by Jett Uchiha. Jett's ninken have shown the ability to use human language, walk on water, develop combat strategies, and track down targets through their enhanced smell. They are supposed to be quite dangerous in combat, as Jett notes that they can tear their opponents apart on her command. She can summon them separately, as she commonly does so with Pakkun, or all together. She can also summon them for special purposes, like she does with his Summoning: Earth Release: Tracking Fang Technique. With this technique, the dogs can travel through the ground following the scent of their target, emerging when the target is found and holding them in place.
