Manchee is Todd's sweet, adorable pet dog who Todd really doesn't want at the start of the trilogy but throughout the first book Todd grows to love. Manchee is killed by Aaron on page 350 of the first book, after Aaron gives Todd the choice of keeping Viola or Manchee alive.
Manchee did a lot of good for Todd. such as carrying out the plan to save Viola, saves Todd from Aaron and Davy many times, and helps him through his hallucinations after Todd is stabbed by Aaron. Manchee is a kind, loving and loyal dog throughout The Knife Of Never Letting Go.
