Flat collars are a type of dog collar that lies flat against the pet's neck. They are typically made from materials like nylon, leather, or fabric and come in various colors and designs. Flat collars usually feature a buckle or snap closure and a metal ring for attaching a leash or ID tags. These collars are commonly used for everyday walks and identification purposes. Unlike other types of collars, such as choke collars or prong collars, flat collars are designed for comfort and safety. They are suitable for most dog breeds and sizes, making them a popular choice among pet owners.
