When is a German Shepherd fully grown?

German Shepherds reach their adult height by around 12 months but continue to fill out in muscle and body width until approximately 18–24 months. Males, being larger, often take closer to 2 years to reach full physical maturity. Consider your GSD fully grown only when it has maintained a stable weight for several months without obvious further filling out.

How much should a German Shepherd puppy weigh at 6 months?

At 6 months, most German Shepherd puppies weigh approximately 17–24 kg (females) or 22–30 kg (males). These are approximate ranges — individual puppies vary. More important than hitting a specific number is a consistent, steady growth curve without sudden jumps or plateaus. Your vet can plot your puppy's growth against standard growth curves at wellness visits.

Should I feed my German Shepherd puppy adult food to slow growth?

No — puppies need the nutrient profile of a puppy food to meet their development needs. The right approach is to choose a large-breed puppy formula, which is designed for controlled growth. Feeding adult food to a puppy can create nutritional deficiencies. The goal is measured, steady growth — not restriction — to protect developing joints.

Can I let my German Shepherd puppy run long distances?

Intensive repetitive exercise such as long runs should be avoided until growth plates close at around 12–18 months. Before that, moderate leash walks, free play, and low-impact activities are appropriate. Discuss exercise intensity with your vet as your puppy approaches 12–15 months.
