When dogs are young, they learn much and what is learned has a lasting impact.
(Sue St. Gelais, Ontario, Canada)
All dogs, regardless of breed, pass through various stages as they grow and develop, physically, mentally, and psychologically. Psychologists use the term critical period to describe a specific time in a dog’s life when certain experiences have a lasting effect upon their psychological development. Understanding these critical periods and a dog’s stages of development will better help you to understand your foster dog’s behavior and how to handle him during these special times.
