Lack of early socialization in puppies can lead to which of the following?

• A. Uncontrolled aggression toward all animals.
• B. Improved tolerance to new stimuli.
• C. Increased fear of new people and environments.
• D. Unconditional obedience.

Answer: (C)

Exposure to a variety of people, animals, and environments during a puppy’s early weeks helps them form positive associations with novelty and learn to read social cues. When that socialization window is missed, the puppy often views new people and places as threats, leading to increased fear and avoidance. This fear can show up as cowering, shaking, or retreat and may generalize to unfamiliar people or settings as the dog grows, making everyday interactions and training much harder. The other options don’t fit because lack of socialization more commonly produces fear-based responses rather than universal aggression, does not create better tolerance to new stimuli, and does not directly relate to unconditional obedience.
