Hot weather is tougher on dogs than most owners realise. When temperatures climb, our dogs can’t cool themselves the way we can – they rely entirely on panting. A cooling vest uses evaporative cooling to actively reduce your dog’s body temperature, making summer walks comfortable and safe. Whether you’ve got a black dog that absorbs heat, a senior who struggles in warm weather, or simply want to extend outdoor time during summer, the right cooling vest makes a genuine difference. We’ve tested the best cooling vests available in the UK to help you find the perfect fit.

Individual Product Reviews
1. Ruffwear Swamp Cooler Zip Vest
Best for: Reliable cooling performance across conditions
The Ruffwear Swamp Cooler Zip is the evolved version of their classic cooling vest, and it shows genuine improvements. The three-layer design works harder to keep dogs cool – a wicking outer layer that reflects heat, an absorbent middle that holds water, and a soft inner mesh that keeps your dog comfortable. The zip closure means on-the-go adjustments, and the reflective trim adds visibility on evening walks.
What’s impressed us most is the consistent cooling performance across different temperatures and activity levels. Even on genuinely hot days, dogs wearing the Swamp Cooler stay noticeably more comfortable. The design allows the vest to be worn over a harness, so you’re not choosing between cooling and control. Ruffwear’s reliability is legendary for good reason.
What we like:
Three-layer cooling system is genuinely effective
Zip closure for easy adjustments
Reflective trim for visibility
Works over harnesses and collars
Worth knowing:
Premium price reflects the engineering
Fit can run slightly large – check sizing carefully
Requires regular soaking for optimal cooling
Specifications:
Sizes: XS through XL available
Material: Three-layer cooling fabric with reflective trim
Cooling duration: Around 2 hours per soak
Suitable for: Adult dogs, puppies from 12 weeks
2. Equafleece T-Shirt Suit
Best for: Affordable, versatile cooling solution
The Equafleece T-Shirt Suit is brilliant because it’s genuinely affordable without sacrificing performance. It functions as a cooling vest when soaked, but also works as a post-exercise recovery suit and even as an anxiety-reducing wrap. This versatility makes it better value than a single-purpose cooling vest.
The lightweight material means your dog stays cool without bulk, and the simple design means nothing complex to manage. Equafleece is UK-based in Devon and understands British dog owners’ needs. The fabric holds water effectively for up to four hours of cooling, and it’s incredibly easy to care for – just rinse and air dry after use.
What we like:
Excellent value for money
Versatile – cooling, recovery, anxiety relief
Lightweight and easy to manage
Long cooling duration – around 4 hours
Worth knowing:
Sizing runs small – many owners recommend going up a size
Fit may not be ideal for very active dogs
Fabric can take a while to fully dry
Specifications:
Sizes: XXS through XL available

Cooling duration: Up to 4 hours
Suitable for: All ages and sizes
3. ThermLow Cooling Vest
Best for: UK-made quality and design
ThermLow is genuinely UK-made and represents brilliant engineering for British hot days. The cooling fabric is specially designed to absorb water efficiently and release it gradually, keeping dogs cool for extended periods. The vest design is ergonomic – it doesn’t restrict movement or chafe sensitive areas.
What impresses us is the attention to detail. The sizing is consistent and true to measurement guides, the stitching is robust, and the overall construction feels like it will last years. ThermLow also provides clear guidance on cooling duration and recharge times, removing any guesswork. For owners who prefer supporting UK businesses, this is an excellent choice.
What we like:
Made in the UK with quality engineering
Consistent sizing that matches measurements
Effective cooling across different temperatures
Excellent customer service and guidance

But this isn’t just about looks – the cooling performance is genuinely excellent, with effective temperature reduction across your dog’s core.
The vest design is carefully engineered to distribute cooling evenly without creating pressure points or restricting movement. The closure system is secure but easy to manage. For owners who want their dog to look good whilst staying cool, Pawdaw represents brilliant design thinking. Their customer service is also exceptional.
What we like:
Premium design and construction quality
Effective cooling performance
Thoughtful, comfortable fit

5. DogLemi Cooling Vest
Best for: Budget-conscious owners wanting basic cooling
The DogLemi Cooling Vest is genuinely affordable and works perfectly well for basic cooling needs. The evaporative cooling technology is the same principle as expensive vests – you soak it, wring it out, and put it on your dog. The materials are adequate, not premium, but they perform their job effectively.
This vest is perfect for testing whether your dog will tolerate cooling wear, or as a backup option. For puppies or dogs still growing into their size, the budget price makes sense. Don’t expect the longevity of premium brands, but for the cost, the value is genuine.
What we like:
Very affordable
Basic cooling technology works effectively
Good for testing before buying premium option
Simple design with few parts to break
Worth knowing:
Materials are basic and may not last seasons of heavy use
Fit can be inconsistent – measure very carefully
Limited colour and size options
Specifications:
Sizes: S through XL available
Material: Basic evaporative cooling fabric
Cooling duration: Around 2 hours per soak
Suitable for: Adult dogs, young adult dogs
Buying Guide: What to Look For
Water Absorption
How well the fabric absorbs water determines cooling effectiveness. Better fabrics hold water longer and release it gradually. Check reviews to see how long cooling lasts after soaking – anything over 2 hours is good, over 3 hours is excellent.
Fit and Coverage
A cooling vest that’s too tight restricts movement and circulation. Too loose and water won’t contact your dog’s skin effectively. The best vests sit snugly without compression. Coverage should include the back, sides, and chest – these areas generate the most heat.
Ease of Use
The best cooling vests are genuinely simple to put on and take off. Velcro or touch-and-close fasteners are quickest. Check if you need to wring it out completely or if light squeezing is enough – simpler is better when you’re managing a hot dog.
Weight and Bulk
When soaked, cooling vests are heavier than dry wear. Consider your dog’s size and whether they’ll tolerate the extra weight. Smaller dogs especially may find heavy vests restrictive.
Dog Size and Breed Guide
| Dog Size | Weight Range | Example Breeds | Cooling Vest Size |
| Small | Under 10kg | Chihuahua, Yorkie, Toy Poodle | XS or Size 1 |
| Medium | 10-25kg | Spaniel, Beagle, Border Collie | S or M (Size 2-3) |
| Large | 25-40kg | Labrador, Golden Retriever, German Shepherd | L (Size 4-5) |
| Extra Large | 40kg+ | Great Dane, Mastiff, St Bernard | XL or XXL |
Measure your dog’s back length from the base of the tail to the neck, and chest circumference just behind the front legs. Always check individual brand sizing as they vary.
How Much Should You Spend?

FAQ
Q: How long does a cooling vest actually cool your dog?
A: Most vests provide 2-4 hours of cooling per soak. Premium options like Equafleece reach 4 hours. You can re-soak mid-walk for longer outings.
Q: Can puppies wear cooling vests?
A: Yes, most brands recommend from 8 weeks onwards. Measure carefully as puppies grow quickly. Budget options make sense while sizing up.
Q: What if my dog hates wearing a cooling vest?
A: Start with short indoor sessions with treats. Some dogs never accept vests, and that’s okay. Alternative cooling methods include ice packs, damp towels, or simply reducing walk time in extreme heat.
Q: Which dogs need cooling vests most?
A: Brachycephalic breeds (bulldogs, pugs), senior dogs, overweight dogs, and black-coated dogs benefit most. Healthy adult dogs in moderate heat might manage without one, but many owners find them genuinely helpful.
Final Verdict
The best cooling vest for your dog depends on your budget, frequency of use, and your dog’s tolerance for wear. If you want peak performance, the Ruffwear Swamp Cooler is unbeatable. For value and versatility, Equafleece is hard to beat. For UK-made quality, ThermLow delivers. Even the budget DogLemi option performs its core function effectively. A cooling vest genuinely makes hot weather safer and more enjoyable for your dog.
