Personally I am torn. Is dressing your pet up in costumes cute, or is it humiliating and embarrassing (for the pet of course). My German Shepard Tinkerbell wears a police dog uniform for Halloween. She seems to enjoy it, but I have not tried dressing her up as a cheerleader or a cartoon character. Her out fit is breed appropriate and not at all humiliating. For your consideration here are some dogs in costume to help you decide.
Thank You For Your Consideration,
