Karyuudo's Attack Dogs

Karyuudo's attack dogs are the dogs from his kennel that he has trained to attack the other competitors in the Survival Game.



Overview
Karyuudo outfitted the dogs with metal mouthpieces to enhance their bites and physical attacks. Though, there were many types of dogs at the kennel, it appears only select breeds wear use in the games, mainly the stronger ones.

In the manga, Karyuudo's dogs wear large metal mouthpieces, whilst in the anime, their teeth are shown to be wearing metal, serrated braces-like devices. Each and every dog apparently has a tracking device on them, so that Karyuudo can monitor them on his computer. He also has a at least one dog fitted with a speaker collar, and listening device to help monitor the situation.

The dogs are controlled by the The Breeder Diary, which allows Karyuudo to control the dogs like an army. The dogs are apparently very well trained, but it is unclear if this is just the effects of the dairy. It is implied the user can see what the dogs see through the phone, or at least relay information.
