The Ruffwear Swamp Cooler helps keep your dog cool in hot, dry weather using evaporative cooling. This dog coat also provides UPF 50+ sun protection and has a leash portal on the back, so it can be worn over most harnesses. 


The Swamp Cooler by Ruffwear is great for dogs that enjoy hiking, biking, running or walking in the heat, playing on the beach, boating or participating in agility trials or dog shows!

The Swamp Cooler dog vest provides maximum cooling through evaporation & heat reflection.  Just soak the dog coat in cool water, wring out the excess and it is ready to put on your dog.  

The Swamp Cooler will keep your dog cool for up to a few hours but this depends on how hot it is and the humidity levels.  With dry, hot Aussie summer temperatures, it will probably last around 45min-1hr.   When it dries, just re-soak with your water bottle or a tap.  Or get your dog to walk in water.  This will 'recharge' the cooling.

Recent updates: Updated external air mesh for improved abrasion resistance and improved water absorption: the new design retains more water in high exposure zones on the vest for a longer charge.

There is also an integrated leash portal which allows you to put the Swamp Cooler over harnesses that have a back clip (Hi & Light, Flagline, Front Range or Web Master Harness.)


The Swamp Cooler is available in 6 sizes and should have a relaxed, loose fit.  Note, it is not essential for it to go all the way to the base of the tail as the majority of cooling will be around the chest.

To size, measure around your dog's girth (the circumference) at the widest part of the chest and right behind the front legs.   You can also measure the neck as the neck on the coat is not adjustable. 

Sizes should be selected based on Chest Measure first.

Size Chest/Girth Measure* Most Important
XXS 33-43 cm (13-17") 34.5 cm
XS 43-56 cm (17-22") 41 cm
S 56-69 cm (22-27")
50 cm
M 69-81 cm (27-32") 56 cm
L 81-91 cm (32-36") 67.5 cm
XL 91-107 cm (36-42") 71 cm

Helps keep my dog cool in summer

My dog doesn’t do well in the heat especially when he has a dark coat and being outside under the shade doesn’t help. After putting on the cooler vest soaked with water it helped a lot, he wasn’t panting as much and breathing was steady

My irish terrier loves this cooling vest. It works well by evaporation but dosnt leave the coat wet like some other brands. Its fits so well, even under a harness.

Swamp Cooler - Cooling Vest

Got the cooling vest for my Border Collie to help with evening walks in Queensland heat.
On the days I can use it (evaporative cooling doesn't really work above 70% humidity) it really seems to help her.

At the same time I got a new vest from Canine spirit (roughware) and like that their is a spot to thread the harness leash clip to.
Would love if the cooling vest had a similar slot on the chest to allow the same for the front harness clip

Prompt delivery and fulfills every promise.

Charlie suffered in the heat now he can run for 2 or 3 times longer. Chasing the birds to his hearts content.

Great cooling vest

I got 2 of the Swamp Cooler - Cooling Dog Vest for my 2 mini dachshunds and they work really well. The vests keep them nice an cool on walks or just when it's extra hot and no air con. I've used ruffwear products before for my mini dachshunds using their float coats (which are fantastic). The sizing for the float coats was the same for the vests and they fit really well. The sizing charts are very helpful, and so where the staff at Canine Spirit. It fits their chest well, and isn't too short on their long bodies. The service at Canine Spirit was amazing answered emails very quickly, and the shipping was exceptional especially at Christmas time. Would recommend this product and company

Excellent Quality and Good Fit

I have just received the Swamp Cooling coat ordered after only three working days. It has been purchased for my rescue Chinese Crested who requires cooling and sun protection in summer. The fit is almost perfect, the neck is a little large but girth and length is perfect. He is tolerating wearing it immediately and although we have not tested it’s cooling properties yet I am very pleased with my purchase and can’t wait to take him to the beach with his brothers. I particularly like the leash portal for when we go walking. I would recommend this coat for any dog needing cooling with added sun protection.

Thank you so much for the awesome review. The details you have included should help other dog 'parents' in their choice as to whether the Swamp Cooler will be best for them. :) Many wags!
