A dog harness is a type of pet accessory designed to secure a dog while walking or exercising. Unlike collars, which can put pressure on a dog's neck, harnesses distribute the force across the dog's body, making them safer and more comfortable for various breeds. They come in different styles, including front-clip and back-clip options, catering to different training needs and dog behaviors. Many dog owners prefer harnesses for their ability to prevent pulling during walks. They are especially useful for small dogs or those with respiratory issues, as they reduce strain on the neck. Additionally, harnesses often feature adjustable straps for a better fit and can include reflective materials for added safety during nighttime walks.
