We went to petsmart Friday, and they have the costumes out. We tried on a ladybug, cow, bumblebee, dinosaur, pumpkin, and Lord knows what else because I forgot. lol None of them fit her just right.. most were too small to go around her neck. The cow came the closest, though. I'm gonna hold out and see if we can find anything else! They had some cute halloween dog skirts and dresses too, but of course, none for the plus sized ladies.
