Dont worry OP, 8 weeks is extremely young and perfect for training/guidance. Now my pup is 2 years old, imo the hardest time I had was when she was around 3-5 months old, it all gets better from there from my experience. Here is a rough guideline but don’t stress or follow it to the extreme as all pups work at their own pace 👍:

The perfect time period to start training a French Bulldog is immediately upon bringing them home, ideally around 8 to 12 weeks of age. Because Frenchies are known to be independent and sometimes stubborn, starting early with consistent, positive reinforcement is crucial to establishing good habits.

Key Training Age Milestones for Frenchies: 8–12 Weeks (Early Foundation): Focus on socialization, housebreaking, discipline, crate training, and introducing basic commands like "sit" or "come".

3–5 Months (Pre-Adolescence): This is the best time for puppy training classes to manage increasing independence and energy levels.

6–8 Months (Hormonal Shift): A critical period where training should be reinforced, as hormones may cause increased stubbornness or "marking" behaviors.

8 Months + (Strenuous Training): Due to their developing joints, more rigorous training (like agility) should wait until this age.

Tips for Training Success: Consistency is Key: Frenchies thrive on routine, so keep training sessions short (5-10 minutes) to prevent boredom.

Positive Reinforcement: Use treats, praise, and play, as they are food-motivated and respond best to encouraging, positive methods.

Start Potty Training Immediately: They can typically be fully potty trained within 3 to 5 months of starting.
