Focus on the Behavior You Want From the French Bulldog
First of all, you must be very clear about the behavior you want the French Bulldog to show. For example, when you perform a certain action, the dog may react in an overly excited way. If that is not the response you want, then you need to design specific training for that issue.

Use a No-Force Training Philosophy
Use positive reinforcement to shape the French Bulldog's behavior and increase the likelihood that correct actions will occur again. Punishment cannot truly teach appropriate behavior, and instead may create fear or increase aggression.
Strengthen Good Behavior
Catch the French Bulldog in the act of doing something right. Whenever good behavior appears, reinforce it immediately. If a clicker or treats are not at hand, then use verbal praise such as ?Good!? The French Bulldog is always learning, so there is always an opportunity to reinforce desirable behavior.

Set Things Up Properly to Ensure Success
Break new behaviors into small learning steps so that the French Bulldog can succeed more easily and the frequency of rewards can increase. When teaching a new behavior, or when the French Bulldog is working in a complex and noisy environment, make sure clicker signals and treats appear often. Even ten reward events per minute may not be excessive in some circumstances.

Teach the French Bulldog Self-Control
We should also understand that a French Bulldog is capable of controlling its own behavior. Sometimes we can manage the environment, and sometimes we can guide the training process, but we must also teach the dog how to stay calm and regulate its emotions.
