Chibi and Buchi

Appearance/Personality
Chibi and Buchi are two big and ferocious dogs, who attack Iggy for no apparent reason, invading Dio Brando's mansion just to satisfy their hunger. Ironically enough, they also have a cowardice side to them, having been frightened by Iggy when he simply threatened to fight back. Despite their nature, their owner loves them deeply.

Chibi and Buchi threaten Iggy while he is searching for Dio's mansion, probably due to Iggy invading their territory. Iggy, not wanting to fight against two ordinary dogs, just scares them.

After running away from Iggy, they find the gate to Dio's mansion and tried to invade, in order to eat Pet Shop. They were not aware of how dangerous this was, due to Pet Shop's shadow appearing from underneath the gate looking like one of a simple and small bird. Their plan backfired when Pet Shop was the one to attack them, decapitating the two dogs and pulling their body under the gate. Their owner eventually found their dead remains being eaten by Pet Shop and was saved by Iggy before the bird could kill him. In return, the kid helped Iggy heal his injuries from the fight.
