I'm not much of a dog person - and the entire POO and it thing doesn't do for me - but I think if I had a dog, I would dress for Halloween. Some people think it is cruel, but really? Every dog enthusiastically enough to be dressed in a Halloween costume is unlikely to have a pretty sweet life.
Some of the coolest pet witch costumes in the catalog this year:
Monkey dog rider PET Halloween costumeThis Fez bear dog riding monkey is so freaky!
Star Wars - Princess Leia dog Halloween - costumeWho came up the idea of design dog costumes? This is for the officially Star Wars fan dog, but if you are in wonder woman, Indiana Jones, Batman or Shrek, these styles also available.
Taco dog Halloween costumeThe Hat makes it.
Zelda bouffant dog Halloween costumeNot sure if the average dog would actually wear a wig and glasses for longer than it took snap a photo, but something tells me that, if I were a dog, I would try and find out if he would.
