Don't leave your pup out of the fun at the next Ugly Christmas Sweater Party! The howl-lidays are more fun than ever when the whole family joins in, including your fur-babies! This dog sweater is inspired by the book, How the Grinch Stole Christmas! It's made in the style of the now-popular ugly holiday sweater, which pokes light fun at the tackiness of early colorful knit Christmas sweaters. But we think these holiday sweaters for dogs are actually quite adorable, inspired by a classic holiday book and as functional as they are fashionable.
