Ruffwear Climate Changer Dog Fleece Pullover
Whether the trail ahead is covered in freshly fallen leaves or a fine layer of frost, the Climate Changer Pullover sweater is an instant favorite for dogs on cool-weather pursuits. Simplicity is at the core of this hardware-free, cozy fleece. The stretch lower panel captures warmth and sheds moisture, working in tandem with the open cap-sleeves to provide hard-to-fit dogs (broad shoulders, thick chests/necks) an alternative fit option with more coverage and full range of motion.
Inspired by springtime blooms and a dog’s penchant for making all things fun, Ruffwear designers brought a playful twist to a technical piece with our first ever pattern option: Blossom.
