Protein is essential for the growth, repair, and maintenance of all body tissues, including muscles, bones, skin, and hair. Working breeds like German Shepherds have a high energy requirement and a high level of physical activity, which can cause wear and tear on their bodies. They need high-quality protein in their diet to help maintain and repair their bodies, as well as to support their lean muscle mass.

Additionally, protein is important for immune function, helping to support the body's ability to fight off infection and disease. German Shepherds, as working breeds, are often used for tasks such as search and rescue, tracking, and protection, which can put them at risk of injury and infection. A diet rich in protein can help support their immune system to keep them healthy and able to perform their duties.

Furthermore, German Shepherds can have sensitive stomachs that makes them prone to food allergies and sensitivities, a diet that’s rich in protein and low in fillers can help alleviate this problem and keep them healthy.

Finally, high-quality protein is also essential for maintaining a healthy coat and skin. German Shepherds have a thick double coat which requires proper nutrition to maintain its condition, thus a diet rich in protein helps promote healthy skin and coat.

Natural herbs have been used for centuries to support the health and well-being of animals, including dogs. Herbs can be used to support various aspects of a dog's health, including digestion and immunity.

When it comes to digestion, certain herbs have been found to have a calming effect on the digestive tract, helping to soothe and ease discomfort associated with gas, bloating, and indigestion. Herbs such as ginger contain compounds that can help relax the muscles in the gut and promote healthy digestion.
