Puppies can start training as early as 7 to 8 weeks old. At this age, they are highly receptive to learning and can begin to understand basic commands and socialization skills. Here are some tips for training your puppy at different stages:

1. **7-8 Weeks**: Start with simple commands like 'sit,' 'stay,' and 'come.' Use positive reinforcement techniques, such as treats and praise, to encourage good behavior. Socialization is also crucial at this age; expose your puppy to different people, pets, and environments.

2. **8-12 Weeks**: Continue reinforcing basic commands and introduce new ones. This is also a great time to start house training. Be patient and consistent, and remember that puppies have short attention spans, so keep training sessions brief and fun.

3. **3-6 Months**: As your puppy grows, you can start introducing more advanced commands and tricks. This is a good time for leash training, as well. Consider enrolling in a puppy training class to help with socialization and to learn from a professional trainer.

4. **6 Months and Beyond**: Continue to reinforce learned commands and introduce new challenges. This is a great time to work on impulse control and manners, such as not jumping on people or begging at the table.

Remember, the key to successful puppy training is consistency, patience, and positive reinforcement. Make training a fun and rewarding experience for both you and your puppy!
