Wigzi Waterproof Sport Collars for Dogs are an innovative new type of collar. These collars are lightweight, waterproof, reflective, and also odour proof. This means your dog won’t bring in damp, musty smells into the house. They repel water and dirt, making them an ideal collar for active dogs. They’re also very easy to clean; simply hand wash with soap and water. These dog collars are tough and durable, and their beautiful colours will stay bright for many years. Compared to most collars, these collars are extremely light weight, too.
