- Perfect Fit for Small Dogs : Available in size L, with a chest circumference of 20.3"-23.4" and a neck measurement of 45cm/15.77". Since the fabric is non-elastic, precise bust measurements are crucial. Allow an additional 2-3cm for comfort. If your dog is between sizes S and M, opting for L is recommended. - Cooling Effect : The innovative microfiber fabric of the Dog Cooling Vest activates when wet, effectively pulling excess heat away from your dog. This helps reduce panting and keeps your pet comfortable in warm weather. - Lightweight & Breathable Design : Constructed from breathable mesh material, this cooling vest absorbs water and sweat while keeping your dog's skin dry. The absorbent cotton layer isolates moisture, while the mesh disperses a refreshing sensation across your dog's body. - Convenience and Practicality : Features dual D-rings on the back for a secure attachment, eliminating the need for collars or safety belts during walks. The back zipper and hook-and-loop closure provide a double layer of security, ensuring the vest stays in place. - Versatile Use Scenarios : Ideal for outdoor activities like hiking, running, or simply enjoying a summer day at the park. The cooling vest is perfect for dogs prone to overheating, providing them with a comfortable and secure fit during various activities.
