Break out the flea collar!

Being half dog-youkai, Inuyasha is probably prone to getting fleas. He certainly has one in this case, the cowardly-but-well-informed flea Myouga. The craven insect is probably doing one of the two things he does best: explaining why he ran away during a dangerous moment, or doing some exposition to help the plot along.
