German Shepherds are famously protective and obedient if trained properly from a young age. They may become aggressive toward strangers if they are not trained properly as puppies, so get a jump on a positive training regimen with a certified trainer as soon as possible. You can rely on your German Shepherd to have boundless energy and enjoy running and playing outdoors. As protective as they are toward others, your German Shepherd is likely to be quickly loving and loyal at home. They’re not big, lovable dopes like Golden Retrievers, but they still show affection.
