Beef pizzle is the penis of a bull or steer. It is commonly used as a dog chew, often called a "bully stick." The term "pizzle" comes from old Germanic and Dutch words for animal penis. In dog products, beef pizzle is cleaned, dried, and sometimes twisted or shaped into a chew treat. These chews are high in protein, low in fat, and can help support dental health by reducing plaque and tartar buildup as dogs chew on them. Bully sticks or beef pizzle sticks are popular because they are natural, highly digestible, and free from artificial ingredients. They come in various sizes and thicknesses to suit different dog breeds and chewing habits. Besides being a treat, they provide mental engagement and help relieve boredom or anxiety in dogs. While beef pizzle is primarily used as a dog treat, it has also been used historically in different cultures for medicinal and culinary purposes. However, its main modern use remains as a natural, nutritious chew for dogs. In summary:
