Final answer:
Dogs lacking early socialization typically exhibit behavioral issues such as fearfulness and aggression. Like humans, they require interaction with others and new experiences early in life to shape their social behaviors effectively.
Step-by-step explanation:
Dogs who didn't receive enough socialization as a puppy are typically more prone to behavioral issues such as fearfulness, aggression toward other dogs, and difficulty adjusting to new environments or situations. Just like humans, puppies require socialization to develop the skills necessary to navigate their social world effectively. Without this crucial learning phase, which usually includes interacting with other dogs and humans, exploring new environments, and experiencing a variety of stimuli, puppies may not learn appropriate social cues and may exhibit problematic behaviors later in life. Similar to case studies of children like the one with Oxana Malaya, this lack of early socialization can lead to long-term developmental and social challenges that are difficult to rectify even with subsequent training or intervention.
