Bully sticks are a popular dog chew made from the dried muscle of bulls, typically sourced from the penis of the animal. They are high in protein and are often used as a treat or reward for dogs. Bully sticks come in various sizes and shapes, catering to different dog breeds and chewing preferences. These chews are considered a natural alternative to synthetic dog treats and are generally digestible. However, it's important for pet owners to supervise their dogs while chewing to prevent choking hazards. Additionally, choosing high-quality bully sticks can help ensure safety and nutritional value for pets.
