product information

The ThermLOW dog cooling coat is the simple 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 (a customised fit is even available) and the most effective cooling you can find, with the chest covered as well as your dog's back. The high quality, super absorbent, evaporative chamois-like material gives amazing cooling, indoors or out. Simply activate the jacket with ordinary tap water and let it work its magic.

Dog cool coat Thermlow

ThermLOW is the best cool coat for dogs on the market, in our opinion, and here's why. The chamois-type fabric we use is of the highest quality, unlike cheaper alternatives. Quality fabric absorbs water better, giving a much longer lasting and effective cooling experience for your dog. We have also included a chest section to ThermLOW - something not offered on other cool coats.

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 - your dog can have one made exactly to their own measurements. Woof!

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.

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

Your dog will feel comfortable and cool. No heavy materials, chemicals or bulky gels - just a special lightweight absorbent 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.

UK made

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.

Important redesign information - ThermLOW has recently had a redesign so if you have ordered one before, you may notice some differences. They are still made of PVA foam fabric but the new fabric is a non-woven PVA foam fabric that is more chamois-like than the previous fabric. The evaporative cooling process and care details are the same. Sewn darts have also been added to the back of the jackets to give them an improved fit.

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.

Don't try to unfold, unfasten or flatten the coat when it is dry. Soak it first to soften the material.

If using every day, you can store it slightly damp in the sealable bag provided. Otherwise, hang to dry.

If necessary, gently hand wash or machine wash at 30 degrees. It is best to fasten the Velcro first to stop it sticking to other pieces of fabric. Do not tumble dry. Do not use fabric softeners or conditioners.

How does it work?

Made from PVA foam with a chamois-like feel. This material 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

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.

Head Hole - 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.

Neck (bespoke sizes only) - If you are also taking a neck measurement for a bespoke size, measure the circumference of the neck at the widest part.

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), 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 your dog's measurements in centimetres (cm).

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).

Cannot survive heat without this
Wednesday, 4 August 2021  |  Jane

This is a superb product. It is well made, better than rival products in quality of materials and workmanship. The coat is an essential requirement for our Border Terrier who is no good in the heat ( above about 20C) . With his cool coat, he walks and does his agility as usual, without it he simply overheats . DELIVERY ( THIS WAS TAILOR MADE ) WAS FOUR DAYS FROM PLACING THE ORDER - THANK YOU FOR THE ADVICE AND THE MAKING !

Cooling vest
Wednesday, 14 July 2021  |  Judith

Just returned from a week camping , our dog wore this daily and definitely helped keep her more comfortable and cool . By the end of the week she was coming to look for her vest to be put on ! Great for the beach .
We kept spare water in the car to refresh as necessary and gave it a good rinse out and end of day . Worth going for the bespoke sizing as could get a bit baggy otherwise .

Well worth the money
Monday, 28 June 2021  |  Judith

Although we have only used it once, it worked beautifully on my Basset Hound. Obviously, owing to a Bassets shape, we had a made to measure one, which was more expensive, but well worth the money. My little girl isnít very keen on dog coats, but as soon as l put it on her, she seemed to realise it was for her own good and took to it straight away, all we now is more sun.
