How to Use?1. Before going out, soak the pet cooling vest in cool water until completely wet. 2. After soaking, remove the cooling jacket and wring out excess water. 3. Put the wrung-out dog cooling coat on your dog before going outside. If the dog cooling vest evaporates too much water during outdoor use, it can be reused by repeating the soaking process. Cool & ComfortableThe canine cooling gear is made of a three-dimensional mesh and polymer resin, which is soft and comfortable. It can absorb heat from around your dog's body and release it, helping your dog stay cool. The outer layer blocks UV rays, the middle layer absorbs and stores water, and the mesh lining keeps your dog dry and comfortable. Adjustable SizeThe chest strap of the cooling dog harness is adjustable to ensure that the vest fits your dog's body and provides a more comfortable wearing experience. By adjusting the length of the strap, the summer dog vest can be more closely fitted to your dog's body, improving comfort and safety. Suitable for Hot SummerThe cooling dog vest is suitable for various outdoor activities in the summer, such as hiking, walking, camping, etc., which can help your dog stay cool and safe in hot weather, making them happier and healthier.
