Frequently Asked Questions
How do I measure my dog for the right vest size?
Measure the girth by wrapping a flexible tape measure around the widest part of your dog's rib cage, just behind the front legs. Use that measurement to pick the vest size; if your dog is between sizes, choose the larger size for comfort and adjustability.
How do evaporative vests compare to phase-change (PCM) vests?
Evaporative vests rely on wetting fabric and airflow to cool — they're lightweight and good for short activities. PCM vests use frozen packs to provide longer, steadier cooling but are heavier and require freezing the packs. Choose based on how long you need cooling and whether you can manage frozen packs.
Can my dog wear a cooling vest all day?
Cooling vests are safe for monitored use, but avoid leaving a vest on unattended for long periods. For evaporative vests, re-wet and allow drying breaks as needed; for PCM vests, follow manufacturer guidance on pack temperature and removal intervals to prevent overcooling or discomfort.
