Character Traits
Key German Shepherd temperament traits to evaluate in a GSD puppy—what they mean for family life, training, and work.
Trainability
Trainability is a psychological trait shown in two ways: a spontaneous willingness to follow the handler (pack leader) and the number of behaviors the dog can learn. A highly trainable German Shepherd is eager to comply and quick to learn new tasks.
Hardness
Hardness is both psychological and physiological—resilience to unpleasant experiences. Dogs with high hardness tolerate significant stress with little lasting effect and often require firmer corrections when disobedient. Physiologically, hardness correlates with the thickness of nerve-fiber sheathing; higher arousal can temporarily increase hardness to the point that corrections become ineffective.
Softness
Softness is the opposite of hardness and is common in wild canids. Soft dogs perceive pain and stress more intensely and may associate the location of a stressful event with the event itself. For example, a soft dog stung by a bee may avoid that spot on the lawn for hours, if not days.
Courage
Courage is the absence of fear toward real or imagined danger. It is primarily genetic—a dog is largely born with it or not. Selective breeding can reduce fearfulness. Because the natural state of the dog is cautious, the confident, courageous GSD we breed for would be at a disadvantage in the wild without human partnership.
Confidence
Confidence is environmentally influenced and can be built through training. By exposing the dog to moderate, manageable stress and then letting the dog “win,” we reinforce that working through pressure is rewarding. Over time, the dog believes in itself more. Note: if stress exceeds what training has prepared the dog to handle, it will revert to its baseline character.
Sharpness
Sharpness is a genetically based tendency to respond to stress with sudden aggression (e.g., a startled bite without warning) and then quickly recover. Sharpness is rooted in fear and requires experienced handling and clear structure.
Temperament
Temperament is genetically based but significantly shaped by environment. We describe it as full, moderate, or poor. A full temperament is lively and engaged; a poor temperament is sluggish and withdrawn. Balanced temperament is ideal for most families.
Sensory Threshold
Sensory threshold is fully genetic and describes how much stimulus is needed to elicit a response. Low-threshold dogs are easily aroused and may whine or scream during agitation; they can overstimulate quickly. High-threshold dogs may seem dull at first and take longer to warm up.
Dogfight Tendency
Dogfight tendency is largely genetic (though environment can amplify it) and refers to dog-directed aggression only. A dog can be perfectly safe with people yet hostile toward other dogs. Unlike rank or fight drive, which often end when the opponent yields, true dogfight tendency can persist to severe outcomes. Careful selection and management are essential in multi-dog homes.
Distractibility
Distractibility is genetically based and environmentally influenced—the tendency to be diverted from a task. High distractibility complicates proofing under distraction and demands more training to maintain performance.
Agility
Agility describes natural speed, sure-footedness, and coordination. An agile German Shepherd can pursue at high speed and turn sharply without losing control—useful for sport and real-world work.
Physical Endurance
Physical endurance reflects muscle tone and conditioning. Better conditioning reduces energy expenditure per task and supports more work over time. Regular exercise increases endurance.
Retrieve Drive
Retrieve drive is the desire to bring prey back to the handler. Dogs with strong retrieve drive happily return a ball or bumper and release it to continue the game. It’s a valuable motivator in obedience and detection training.
