For dogs that don't stop moving when the thermometer says they should. The Río Vest is an evaporative cooling vest — soak it in cool water, wring it out, strap it on, and the fabric releases that water slowly as your dog moves, pulling heat off their core the way sweat works for you.
- Hours of evaporative cooling per soak — re-wet anywhere there's water
- Lightweight, breathable layers — built for walks, hikes, and fetch, not lounging
- Light-reflective outer deflects sun instead of absorbing it
- Adjustable fit across chest and belly
Check the size chart below before ordering — a loose vest cools poorly.
Size chart
Measure your dog's chest girth — wrap a soft tape around the widest part of the chest, just behind the front legs. This is the measurement that matters most. Then match it to the chart:
| Size | Chest girth | Back length | Typical breeds |
|---|---|---|---|
| Small | 14–20 in (36–51 cm) | 10–14 in (25–36 cm) | Chihuahua, Yorkie, Mini Dachshund, Shih Tzu, French Bulldog (slim) |
| Medium | 20–27 in (51–69 cm) | 14–18 in (36–46 cm) | Beagle, Cocker Spaniel, Whippet, Border Collie, French/English Bulldog |
| Large | 27–35 in (69–89 cm) | 18–23 in (46–58 cm) | Labrador, Golden Retriever, Husky, German Shepherd, Boxer |
Between sizes? Size up. The vest cools by evaporation, and a slightly looser fit lets more air move through than a snug one.
Flat-faced breeds (Bulldogs, Pugs, Boxers) often have a deeper chest than their length suggests — measure chest girth and size to that number.
Still unsure? Email us your dog's chest measurement and we'll recommend a size.
Río Vest FAQ
How long does one soak last?
Hours rather than minutes, but it varies with heat, humidity, and how hard your dog is going. Re-wet anywhere there's water to restart the cooling.
Will my dog be dripping wet?
No — wring the vest out before strapping it on. Damp, not soaked.
Does it work in humid climates?
Honest answer: evaporative cooling is strongest in dry heat. In high humidity it still helps, but less — prioritize shade, water, and rest breaks there.
How do I size it?
Measure chest girth just behind the front legs and match the size chart above. Snug but not tight — if your dog is between sizes, size up or email us the measurement.
