Summer walks are the best part of the year
Warm afternoons can leave a small dog panting before you're halfway around the block. The Dog Cooling Fan Vest is a lightweight sun shirt with a built-in fan that moves air across your dog's back, helping make warm-weather walks, patio time and outdoor days feel more comfortable.
- Neighborhood walks on warm days
- Lazy afternoons on the patio
- Outdoor days in the sunshine

A fan built right into the vest
The built-in fan keeps air circulating across your dog's back, where it's needed most, while the breathable, sun-shielding fabric helps block direct sun. The vest slips on quickly, so it's easy to grab on your way out the door.
- Air moves across their back
- Fabric helps block direct sun
- Slips on quickly

More than a plain summer shirt
A plain dog shirt only covers up. This one adds a built-in fan for moving air, in breathable fabric that's light enough for hot days. The bright mint green helps your dog stand out on walks, and it comes in four sizes, S to XL, for small and medium dogs.
- Built-in fan plus sun-shielding fabric
- Bright mint green stands out
- Sizes S to XL by chest
