Adolescence/Juvenile stage occurs during which age range?

• A. 3-6 months
• B. 18-24 months
• C. 6-18 months
• D. Birth to 2 weeks

Answer: (C)

The main idea here is understanding how dog development is segmented and when adolescence/juvenile behavior typically appears. In most dogs, the adolescence or juvenile period starts around about six months of age and continues through roughly 18 months, with some variation depending on breed and individual maturation. This window captures hormonal changes that influence behavior, a surge in energy, and the emergence of more independent or testing behaviors. Training during this time should emphasize structure, consistency, impulse control, and ample physical and mental exercise to channel the energy constructively. Because the exact timing can shift a bit by breed—larger breeds often mature later and may show adolescent tendencies for a longer period—the six-to-eighteen-month range is the most widely used general guideline. The other age ranges you might see are associated with earlier puppy stages or later into adulthood, not the typical adolescence/juvenile window.
