If there’s one thing every French Bulldog owner learns fast, it’s that Frenchies and heat don’t mix. George starts panting if the temperature hits 23°C, and anything above 28°C is a genuine health risk.
French Bulldogs are brachycephalic, their shortened airways make it much harder for them to cool themselves through panting (which is how dogs regulate body temperature). This makes them extremely vulnerable to heatstroke, which can be fatal.
A cooling vest won’t replace shade, water, and air conditioning, but it’s an essential layer of protection for walks, outdoor time, and travel in warm weather. Here are the 5 best cooling vests and bandanas I’ve tested on George.

How Cooling Vests Work
Most dog cooling vests use one of three technologies:
- Evaporative cooling. You soak the vest in water, wring it out, and the evaporation draws heat away from your dog’s body. Works like a wet towel, but more effective and controlled. Best for dry climates.
- Phase-change cooling. Uses special materials that absorb heat at a specific temperature. You “charge” them in the freezer or cold water, and they maintain a cool temperature for hours. Works in any humidity.
- Reflective cooling. Reflects sunlight away rather than actively cooling. Less effective alone, often combined with evaporative tech.
For French Bulldogs, evaporative and phase-change cooling are the most effective options.
The 5 Best Cooling Vests for French Bulldogs
1. Ruffwear Swamp Cooler. Best Overall
The Ruffwear Swamp Cooler is the cooling vest I trust most with George’s safety. It uses a three-layer evaporative cooling system: the outer layer reflects heat, the middle layer stores water for evaporation, and the inner layer wicks heat from your dog’s body.
Why it’s great for Frenchies:
- Three-layer evaporative cooling technology
- Reflective outer layer blocks solar heat
- Chest coverage where Frenchies carry the most heat
- Side-release buckles for easy on/off
- Leash portal so you can use it with a harness
- Light-colored to reflect sun
How to use: Soak in water for 1-2 minutes, wring out excess, and put on your Frenchie. Re-wet every 20-30 minutes in high heat. Lasts 1-2 hours per soak depending on conditions.
Watch out for: Not effective in very humid conditions (evaporation requires dry air). In humid climates, consider a phase-change option.
Price: ~€40-55
2. Hurtta Cooling Vest. Best for Extended Outdoor Time
Finnish brand Hurtta knows extreme weather. Their cooling vest holds more water than most competitors, which means longer cooling times between re-wetting. The fit is excellent for barrel-chested breeds like French Bulldogs.
Why it’s great for Frenchies:
- High water absorption, longer cooling periods
- Excellent chest and back coverage
- Reflective piping for visibility
- Secure fit with adjustable straps
- Durable construction that lasts years
How to use: Submerge in cold water for about 5 minutes. Wring out and put on. Re-wet every 30-45 minutes.
Watch out for: It’s heavier when wet than the Ruffwear, which some smaller Frenchies might not love. Test with short sessions first.
Price: ~€45-60
3. Trixie Cooling Vest. Best Budget Option
The Trixie cooling vest does the basics well at a fraction of the price. Soak it, wring it, put it on. The evaporative cooling isn’t as sophisticated as the Ruffwear or Hurtta, but it absolutely works for short walks and garden time.
Why it’s great for Frenchies:
- Very affordable
- Simple soak-and-wear design
- Decent chest coverage
- Hook-and-loop closure (easy on/off)
- Light blue color reflects sunlight
- Available in sizes that fit Frenchies well
How to use: Soak in water, wring out, put on. Re-wet every 15-20 minutes.
Watch out for: Dries out faster than premium options. Not ideal for walks longer than 30 minutes without re-wetting.
Price: ~€15-20
4. Alcott Mariner Cooling Bandana. Best Cooling Bandana
Sometimes you don’t need a full vest. For quick outings, car rides, or mild warm days, a cooling bandana around the neck is enough. The Alcott Mariner uses evaporative cooling in a simple bandana format.
Why it’s great for Frenchies:
- Lightweight, doesn’t add bulk
- Easy to put on and take off
- Cools the neck area (major blood vessels close to surface)
- Can be used in addition to a cooling vest
- Machine washable
How to use: Soak in cold water for 5 minutes, wring out, tie around neck. Re-wet as needed.
Watch out for: Less coverage than a vest. Use for mild heat only, not as primary cooling in extreme temperatures. Be careful not to tie it too tight on brachycephalic breeds.
Price: ~€10-15
5. CoolPets Cooling Mat + Vest Combo. Best Phase-Change Option
For humid climates where evaporative cooling doesn’t work well, phase-change technology is the answer. The CoolPets system uses special polymer crystals that absorb and hold cold temperature from the fridge or cold water.
Why it’s great for Frenchies:
- Works in humid conditions (unlike evaporative)
- Maintains cool temperature for 1-2 hours
- Can be recharged in fridge or cold water
- Non-toxic gel if punctured
- Vest + mat combo for home and outdoor use
How to use: Place vest inserts in fridge for 2 hours (or cold water for 20 minutes). Insert into vest and put on your Frenchie.
Watch out for: The inserts add weight. Make sure your Frenchie is comfortable with the extra bulk. Also more expensive upfront.
Price: ~€35-50

When to Use a Cooling Vest on Your French Bulldog
A cooling vest is recommended whenever:
- Temperature exceeds 22-24°C. This is lower than you’d think. Frenchies start struggling well before most dogs.
- Walking on pavement. Hot pavement radiates heat upward, heating your Frenchie from below AND above. Test with the back of your hand: if it’s too hot for you, it’s too hot for your dog.
- Traveling in a car. Even with AC, cars can have hot spots. A cooling vest provides extra safety.
- Outdoor events. Markets, parks, outdoor cafes, anywhere your Frenchie might be in warmth for extended periods.
- After exercise. Even short play sessions can overheat a Frenchie. Cool them down immediately.
Signs Your French Bulldog Is Overheating
Know these warning signs, they can escalate to heatstroke fast:
- Excessive panting. Heavier and faster than normal
- Drooling. Thick, ropy drool
- Bright red tongue and gums. Or alternatively, very pale gums
- Glazed eyes. Distant, unfocused look
- Stumbling or weakness. Loss of coordination
- Vomiting or diarrhea. Especially if sudden
- Collapse. Medical emergency. Get to a vet immediately.
Emergency cooling: If your Frenchie shows signs of heatstroke, move them to shade immediately, apply cold water to their paws, belly, and ears, and get to a vet as fast as possible. Recent veterinary research confirms cold water immersion is the most effective cooling method. The old advice to avoid ice water has been debunked.
My Pick for Most Frenchie Owners
The Ruffwear Swamp Cooler is the best overall cooling vest for French Bulldogs. It’s well-designed, effective, and the leash portal means you can layer it with a harness.
If you’re on a budget, the Trixie Cooling Vest gets the job done for short walks.
If you live in a humid climate, the CoolPets phase-change system is your best bet since evaporative cooling doesn’t work well in high humidity.
And honestly? Get a cooling bandana too. It’s cheap, easy to keep in your bag, and perfect for those unexpected warm moments.
