GERMAN SHEPHERD DOGS
(Working Lines)
"The breeder on a small scale, one who works with one or two bitches, is the most suitable breeder for working dogs because he can care for his breeding animals and their progeny… and can produce sound strong animals that can be trained."

Puppy Development Stages
Weeks 3-14: Socialisation Period. If puppies are socialised later than 14 weeks, (or in some dogs, possibly 12-14 weeks) shyness or aggressiveness may dominate the dog's long term behavior.
Weeks 6-8: Optimum Socialisation. If puppies are socialised earlier, shyness often develops, along with over-dependence on owner, as in separation anxiety, leading to over protectiveness.
Weeks 8-10. Fear Imprint. Fear display experiences maybe permanently impressed causing defensive reactions in some circumstances.
Weeks 12-14: Puberty Onset. Meaningful sexual mounting often occurs. Males display erections.
Weeks 18-40: Protective-Aggressive. Barking at strangers and other territorial and social group protective tendencies may occur. Leg lifting may begin in males.
Weeks 35-56: Functional. Many dogs become more serious about protective-aggressive behavior. A general persistence in behavior problems is noted and corrections become more difficult.
Weeks 104-208: Achievement. Protective, aggressive behavior can become especially purposeful. Problem behavior appears to become self rewarding, habitual. Corrections markedly more difficult.
