Australian Shepherds require a balanced diet tailored to their high energy levels and active lifestyle. This breed benefits from high-quality dog food rich in proteins and fats to support their muscular build and stamina. It's also essential to monitor caloric intake to prevent obesity, especially in less active individuals. Given their risk for certain genetic issues like the MDR1 mutation, which affects drug metabolism, avoiding foods with potential drug interactions, like those containing ivermectin, is advisable. Regular consultations with a veterinarian can ensure their nutritional needs are met based on age, health, and activity level.
