This is about the Main Character. For the future version of Harold, see Future Harold. For the past life of Harold, see Pirate Harold.

Harold is one of the main characters of Bunnicula.


Harold's history is mostly unknown, but it is known that Mina got him as a puppy during the last time she saw her old imaginary friend, Hamburger Cheese.[1]


Harold appears to be a short-haired, brown mutt or some breed of Herding Dog and has a blue collar, a big nose, small floppy ears, short tail, a mop of messy dark brown hair on top of his head, and a large round belly


Harold is a typical loyal dog and loves his brothers, Chester and Bunnicula, and their owner, Mina, but isn't the sharpest tool in the shed and is very ignorant when it comes to Chester being in danger. However, Harold can be smart when the plot calls for it and is quite insightful when there is something suspicious going on. He also loves having fun with Bunnicula and goes along with his mischief. 


Mina Monroe

Harold is deeply devoted and loyal to Mina. He will always protect her when she is in danger and loves cuddling up with her when they go to bed. Harold was excited to see in the future that he and Mina will be able to communicate and work together in being a team.


Harold frequently annoys Chester with his stupidity and the fact that he and Bunnicula are best friends. However, the two do have a brotherly relationship and always look out for each other when they're in danger. Harold will sometimes call him "Chesty".


Out of all of his brothers, Harold gets along with Bunnicula the most. Since Bunnicula can't talk, Harold usually has to translate for him. Harold lives for Bunnicula's supernatural adventures and mischief, because they always lead to something exciting.


Harold fell head over heels for Fluffy, not knowing that she was trying to kill Bunnicula. Luckily, Harold's kindness and Bunnicula's bravery helped Fluffy realize that not all vampires are bad.

Episode Appearances


  • In the books, Harold was a ponderous, thoughtful character, forced to put up with the eccentricities of Chester and the new rabbit. His appearance in the book is also remarkably different, resembling an Old English Sheepdog, though he claims to have Russian Wolf Hound in him as well.
  • Sometimes, Harold eats things that are actually poison for dogs such as chocolate, pickles, and cheese. Usually in the books, he would question this whenever Toby tried to give him these things.
  • In Lafitte's Lucky Locket, he is reincarnation of Pirate Harold.
  • Harold was shown being given as a present to Mina on her 5th Birthday when he was a puppy. Since Mina turns 13 during the course of the show, that would mean Harold is about eight years old.
  • Like Chester, Harold doesn't appears for four episodes.
