The best time for puppy training is during the critical socialization period, which typically occurs between 3 to 14 weeks of age. During this time, puppies are particularly receptive to new experiences, sounds, sights, and interactions with people and other animals. Here are some key points to consider:

1. **Early Socialization**: Start exposing your puppy to various environments, people, and other dogs. This helps them develop confidence and reduces the likelihood of behavioral issues later in life.

2. **Basic Commands**: Begin training basic commands like 'sit', 'stay', 'come', and 'down' as early as 8 weeks. Use positive reinforcement techniques, such as treats and praise, to encourage good behavior.

3. **Short Sessions**: Keep training sessions short and fun, around 5-10 minutes, as puppies have a limited attention span.

4. **Consistency is Key**: Use the same commands and rewards consistently to help your puppy understand what you expect from them.

5. **Gradual Exposure**: Gradually introduce your puppy to new experiences, ensuring they are positive. For example, if introducing them to a new dog, ensure both dogs are calm and friendly.

6. **Ongoing Training**: Training should be an ongoing process. Even after the critical period, continue reinforcing commands and socialization throughout their first year and beyond.

In summary, start training your puppy as early as possible, ideally when they are around 8 weeks old, and continue throughout their development to ensure a well-adjusted and well-behaved adult dog.
