Contrary to popular belief, puppyhood ends at four months of age.  During the fifth month your dog, no matter how small, transitions into adolescence and by six months you have a full blown teenager on your hands.  

Adolescence generally lasts from six months right through two years of age.  

Nine months to eighteen months is generally the most difficult time for most owners.

With proper puppy training, this process can be less painful for everyone involved.
