A bully stick is a popular dog chew made from the dried and processed muscle of a bull's penis. These treats are high in protein and are often used to promote dental health by helping to reduce plaque and tartar buildup as dogs chew on them. They come in various sizes and shapes to accommodate different dog breeds. Bully sticks are considered a natural and digestible option for dogs, making them a favored choice among pet owners. However, it's important to supervise dogs while they chew to prevent choking and to ensure they do not consume too much at once. Many brands offer bully sticks that are free from additives and preservatives.
