Dog vests are specially designed garments for dogs that serve various purposes. They can provide warmth during cold weather, protect against rain, or even offer visibility during nighttime walks. Some vests are made with reflective materials to enhance safety, while others may include pockets for carrying small items. Additionally, dog vests can be used for training and support. For example, service dogs often wear vests that identify their role and allow them to assist their handlers effectively. Other vests, like life jackets, are designed for water activities, ensuring that dogs stay safe while swimming or boating.
