This is information I believe everyone needs to know about dogs and differing dog breeds. 

Puppy Time Line

Birth to 2 Weeks: Neonatal Period; suckling.

2 Weeks to 3 Weeks: Transitional Period; eyes open.

3 Weeks to 12 Weeks: Socialisation Period; they will startle to sound, at around week 5 will show interest in humans.

12 Weeks to 16 Weeks: Juvenile Period; showing signs of maternal separation and distant exploration.

16 Weeks to 12 Months: Adolescent Period: Growth Spurts and life as a Teenager = Puberty.

12 Months to 4 years: Maturity; if trained properly your dog will become a trustworthy member of your family.



Canine Motor Patterns / Breed Specific Drives (instinctive behaviours)

>> means two motor patterns are connected.      
_____ means the motor pattern is emphasised.   
(Fault) means the motor pattern is not wanted in the breed.

HOWEVER not all dogs within a breed, or even within a litter, will show these motor patterns as listed. For example lots of dogs continue to bite into adult hood as they never learn teething biting and playbiting which are both normal puppy behaviours are an unwanted behaviour.  Other dogs, for example the pointers, have dogs within the breed that have the 'Eye' behaviour to such extent that they will stand 'at point' staring at a leaf for hours and are hard to distract.
