Train your German Shepherd to be a guard dog with obedience training. Your dog should understand that you are the master. Use a clicker to teach her the basic commands necessary: come, sit, stay, and down. See "How to Train Your Dog Yourself" in References to help you with obedience training.
German Shepherd - Dog Lover
German Shepherds can be a variety of colours, the most common of which are the tan/black and red/black varieties. Both varieties have black masks and saddles. Rarer variations include the sable, all-black, all-white, liver and blue varieties. The all-black variety is acceptable; however, the blue and liver are considered to be serious faults and the all-white is grounds for instant disqualification in some standards. This is because the white coat is more visible, making the dog a poor guard dog, and harder to see in conditions such as snow or when herding sheep.
and dense with a thick undercoat. The coat is accepted in two variants; medium and long. The long-hair gene is recessive, making the long-hair variety rarer. Treatment of the long-hair variation differs across standards; they are accepted under the German and UK Kennel Clubs but are considered a fault in the American Kennel Club.
