24. Need for Early Socialization
Chihuahuas benefit greatly from early socialization to help them become well-adjusted and less prone to nervousness around new people or situations. Introducing them to different environments, people, and other animals at a young age helps build their confidence. Proper socialization can prevent behavioral issues and make them more adaptable.
