Product info

The ThermLOW dog cooling coat is a simple and effective way to keep your dog cool and comfortable even on a hot summer’s day. Our cool coat has been designed for the best fit and the most effective cooling you can find, with your dog's chest covered as well as their back. A dog's chest is a major part of the body when it comes to cooling down, so this is a massively important part of any good dog cool jacket.

Dog cool coat Thermlow

The high quality, super absorbent, evaporative foam fabric we have sourced especially for ThermLOW gives our garment amazing cooling, whether indoors or out. Simply activate the jacket with ordinary tap water and let it work its magic.

Specially designed to keep your dog cool in situations where they are at risk of feeling hot or overheating.

A cooling coat or vest provides relief from the effects of heat in hot weather and during or after exercise. Perfect for walks, travelling and activities. Can even be used indoors.

ThermLow British made UK dog cooling coat

We have produced the best cool coat for dogs on the market, in our opinion, and here's why. The thick non-woven foam fabric we use is of the highest quality and is extra thick for an amazing cooling ability, unlike cheaper alternatives or other brands you may come across. Quality fabric absorbs water better, giving a much longer lasting and effective cooling experience for your dog.

We have also included a very important chest section to ThermLOW cool coats plus sewn darts in the back to give them an exceptional fit - something not offered with other brands of cooling garments. Cooling a dog's chest area is a really effective way to quickly and effectively provide relief against heat. Having front body coverage was therefore the pivotal part of our design.

Each garment is expertly handmade in the UK and beautifully finished, for years of use. Not only that but if your dog is not a standard size, do not worry - we offer bespoke sizes so your dog can have one made exactly to their own customised measurements. Woof!

Your dog will feel comfortable and cool. No heavy materials, chemicals or bulky gels - just a special lightweight yet thick absorbent foam material activated by water. These dog cooling coats are soft, light, comfortable to wear and 100% safe. You will be amazed at how well they work.

Other cooling coats tend to be a standard jacket cut that lays over the dog’s back and fastens at the front and belly. The ThermLOW is different. This cooling vest pops over your dog’s head for the perfect fit and an adjustable Velcro tummy strap secures it. ThermLOW's clever design means that the vest covers your dog’s chest as well as their back, covering and cooling more areas of your dog than other designs on the market. It also makes it much less likely to slide sideways when in use.

We also use a much high quality material in our product, making it very highly performing. Your dog will be cooler for longer and less water top-ups will be needed compared to other cool coats on the pet market.

Your dog will feel comfortably cooler - not cold or chilly but just right. The material is durable and won’t easily rip or tear. You can expect years of use and will soon wonder how you managed without it.

Cool coat use and care

Soak in water from the cold tap for a few minutes, until soaked through. Lightly squeeze out any excess water (do not wring), place your dog’s head through the vest and secure with the Velcro straps. Top up with water whenever it starts to dry out.

The material hardens as it dries. Do not try to unfold, unfasten or flatten the coat when it is dry. Soak it first to soften the material.

When not in use, fold the damp / supple garment into the shape you wish to store it and let it dry naturally. If using every day, you can store it slightly damp in the sealable bag provided. It is not recommended to store the damp cool coat in the plastic bag for more than a day as it may start to smell or spoil the material.

ThermLOW Dog Cool Coat

If necessary, gently hand wash or machine wash on a low / gentle cycle (max 30 degrees). Fasten the Velcro first to stop it sticking to other pieces of fabric. Wash separately in case of colour run. Do not use fabric softeners or conditioners. Do not tumble dry.

How does it work?

Made from PVA foam fabric - a material which is great at absorbing and retaining water. It is also durable. The ability of PVA foam to retain water makes it ideal for cooling products. The water held in the material slowly evaporates, drawing heat away from your dog’s body and reducing their temperature. The cooling effect lasts until the coat starts to dry out, which can be an hour or two on a very hot day and quite a few hours on a typical warm day. To reactivate simply soak in water again or poor some water over it on your dog.

When can I use it?

Use at home, on walks, travelling in the car, during activities such as Agility or Flyball, after exercise - any time you need to prevent a rise in temperature or lower your dog's temperature.

when to wear ThermLOW dog cool coat

It is best used as a preventative measure but can also be used to reduce a dog’s temperature if they are already feeling the effects of heat.

How will I know it is working?

Your dog will visibly pant less and will be able to enjoy walks and activities for longer and on warm days than they can without the cooling vest. It will feel cool to the touch. Touch it and see. Or put your hand under the coat and you will notice your dog feels noticeably cooler.

Can be worn outside or even indoors to cool your dog down.

Measuring guide

measuring guide for dog cooling coat

Please measure your dog to get the correct fit. Use a soft tape measure and measure your dog when they are standing up.

Length - Measure from the base of the dog's neck to the base of the tail.

Girth - Measure around your dog's middle, approx halfway between the front and back legs. We give an average girth measurement below but please note that there is a lot of Velcro so you have lots of adjustment either side of that average.

Neck Opening - To check if the garment's head hole is suitable for your dog, please make the appropriate sized loop with your tape measure, place it over your dog's head and check that it sits comfortably below their neck line.

Bespoke Sizes (extra measurements needed) - Please measure the circumference of your dog's neck at the widest part (for neck measurement) and around your dog's body behind their front legs at the deepest part of the chest (for the chest measurement).

Bespoke sizes

If you are ordering a bespoke garment (made especially to fit your dog if they do not fit any of the standard sizes above or if they are a certain shape e.g. greyhounds), please choose a bespoke length from the size drop-down box and then enter your dog's actual measurements in the boxes provided. The maker will use those measurements to make a coat that fits your dog. Approx. 10% is added to the neck measurement so that it sits comfortably at the neck and fits over the dog's head.

Please measure carefully and state all your dog's measurements in centimetres (cm).


Greyhounds and breeds like greyhounds will always need a bespoke garment to be made. The chest panel will need to be narrower and longer, the neck opening will be different to standard and the back will be curved. If your dog is a greyhound or greyhound shape, please always choose the bespoke option and state your dog's breed, thank you.

Returns or exchanges

ThermLOW must be returned within 14 days in the sealed bag provided and still in its soft and supple state. Try the coat on your dog. If it does not fit please fold it back up and put it straight back into the sealed bag. Coats should not be soaked or allowed to dry out if they are going to be returned or exchanged. Thank you.

Returns or exchanges cannot be accepted for bespoke coats (where you have supplied measurements and the coat has been made to fit your dog).
