A well-balanced diet plays a crucial role in maintaining an Australian Shepherd's overall health and extending their lifespan. As they mature, Aussies require approximately 1,500-2,000 calories per day, divided into three main meals. A high-quality dog food with moderate protein (around 22-25%), fat (10-15%), and carbohydrate content (40-50%) will provide the necessary nutrients for optimal health. It is also essential to consider dietary factors that can impact lifespan, such as obesity, allergies, and food sensitivities. Providing a balanced mix of fruits, vegetables, and omega-3 rich ingredients can help support their digestive health and reduce the risk of chronic diseases. A daily routine of feeding high-quality kibble, accompanied by small portions of healthy treats and fresh water, will keep your Aussie thriving for years to come.
