Canada Pooch’s evaporative cooling vest is a mid-budget soak-and-wear option for warm walks and light trail approaches. Breathable mesh holds water so airflow can pull heat away as it evaporates.
It will not replace shade, timing, and drinking water — especially in humidity — but it is a practical tool when Swamp Cooler pricing is more than you want to spend for neighborhood summer miles.
Measure girth, wring excess before car rides, and re-soak when the vest dries out.
