Nutrition: Choose a complete food suited to large, active breeds. Quality matters more than marketing. What suits one shepherd may not suit another; watch your dog, not the label.

Life stages: Puppies need food that supports steady growth — not rapid growth, which stresses developing joints. Adults need maintenance nutrition. Seniors benefit from adjusted calories and joint support.

Weight management: Body condition is a better guide than the bag's recommendation. Adjust to keep your dog lean. A slow feeder and measured portions prevent the gorging shepherds are prone to.

Treats: Useful for training, but they count. Keep treats small and reduce meal portions accordingly.

Supplements: Joint support can help susceptible dogs, but is not a substitute for good base nutrition, weight control and appropriate exercise. Talk to your vet before adding supplements, particularly for growing dogs.

Healthy body condition: Ribs felt easily under light pressure, a visible waist from above, and a tucked abdomen. If you can't feel the ribs, the food — not the dog — needs adjusting.
