Collection: Cooling Dog Harness | NeoCool™ Sport

Introducing the Cooling Dog Harness from the NeoCool™ Sport Collection by Wag Trendz® - the world’s first patent-pending perforated neoprene harness engineered for all-day temperature control.

Crafted for active and heat-sensitive pups, this high-airflow design delivers unbeatable ventilation, rugged durability, and secure control - plus matching leashes, collars, and bag holders that ensure your dog stays cool, comfortable, and stylish on every adventure.

Backed by independent third-party lab testing, NeoCool's perforated neoprene releases trapped heat and moisture 85% more efficiently and allows more than 2.5× the airflow against your dog's body compared to standard neoprene — and because many traditional harnesses use even less breathable materials, the real-world difference your dog feels can be even greater.
