10 Best Cooling Shirt For Dogs 2025 in the United States

The Ruffwear Swamp Cooler Dog Harness is designed to keep dogs comfortable during hot weather by using an evaporative cooling system. Its polyester outer layer reflects heat while an absorbent middle layer stores water to help cool your dog through evaporation. This cooling method is effective if you regularly wet the harness, but it won’t provide continuous cooling without re-wetting.

The harness includes a padded handle and well-designed chest and belly panels that distribute weight evenly, making it easier to lift or support your dog during outdoor activities. Fit is highly customizable with six adjustment points, which helps ensure it stays secure and comfy on a variety of dog sizes, especially large to extra-large breeds. It’s also fairly easy to put on and take off, which is convenient for daily use. The harness is durable enough for active dogs, thanks to its quality polyester material and solid construction. Reflective trims and a light loop add safety for walks in low light, which is a thoughtful design touch.

Since it requires hand washing, cleaning might be a bit more involved compared to machine-washable options. While it’s primarily a harness rather than a traditional cooling shirt, it serves well for outdoor, active dogs that need both cooling and lifting support. For those seeking a cooling solution combined with a sturdy harness, this model is a solid choice, though other alternatives may provide continuous cooling without the need for re-wetting.

The Ruffwear Swamp Cooler Dog Vest is designed to help dogs stay cool during warm-weather activities like hiking and walking. Made from durable polyester with an updated air mesh, it holds water well for evaporative cooling while reflecting heat with its outer layer. This vest is easy to use—you just soak it in water, put it on your dog, and it starts cooling immediately. The inner mesh lining keeps your dog comfortable and dry, and the relaxed fit offers good sun protection with UPF 50+.

It’s also convenient to wear alone or over most harnesses, thanks to a leash portal and side-release buckles. The vest comes in sizes for all breeds, though this particular model is extra small and best suited for small dogs. At just under 3 ounces, it’s lightweight and won’t weigh your pup down. Some users note that while the vest holds water well, the cooling effect may diminish after extended periods in very hot conditions, so re-wetting might be necessary.

The vest’s design focuses more on function than flashy style, which may or may not appeal depending on your preference. If you want a practical, easy-to-use cooling solution that also protects against sun exposure, this vest is a solid choice. It balances durability and comfort, making it well suited for active dogs and outdoor adventures in the heat.

The Sychien Dog Cooling Shirt in size XXX-Large is designed to keep large breeds like Labradors, German Shepherds, and Doberman Pinschers cool and comfortable during the summer. Made from a blend of 95% Rayon and 5% Spandex, it promises breathability and quick-drying properties, making it an excellent choice for hot weather. The material is soft, stretchy, and lightweight, allowing for easy movement and comfort for your pet.

Its striped design in purple/white and grey/white adds a stylish touch, making it suitable for outdoor activities or holidays. The shirt features a sleeveless pullover design, which makes it easy to put on and take off, and it has a higher cut in the belly area for convenient potty breaks. With its strong elasticity and well-sewn construction, it offers durability and a good fit for dogs weighing between 80 to 115 lbs.

The limited size range might be a drawback for owners of smaller or extra-large breeds. Additionally, while it offers sun protection and moisture-wicking capabilities, it may not provide sufficient warmth in very cold weather despite its claim to maintain warmth. The shirt is machine washable, ensuring easy maintenance. If you have a large dog and are looking for a cooling solution that is both functional and stylish, this product could be a great fit.
