It is no secret that we're big animal lovers in these parts -- and that's perhaps never more true than the Halloween season.
Last year, we asked our readers to submit photos of their furry friends decked out in their best costumes for the season. We were so impressed by the many submissions, that we're doing it again this year!
Scroll down to check out already-submitted pets-in-costumes, plus some of our favorite submissions from last year. Add a photo of your own costumed pals by clicking the "+ Add a slide" button.
