Method 1: Every time you find a bulldog biting something (no matter what it bites), you should stop it in time. For example, yell at the dog, hit the floor hard to stop the dog, or play music to stop the bulldog from biting. Of course, after the dog stops biting, it is necessary to carry out criticism and education, and necessary punishment is also possible (for example, the owner says a few words and punishes the dog for sitting still for a few minutes, etc.). The purpose of this is to make the bulldog associate biting with punishment, let the bulldog understand that biting will be punished, and let it gradually get rid of this bad habit in the future.
Method 2: Bulldogs will bite because they want to relieve the discomfort of their tusks during the special period of changing their teeth. In view of this situation, the owner cannot punish the dog casually. It should be understood and tolerated, and of course, some special chewing gum and sticks should be prepared for dogs, so that bulldogs can have something to chew at any time and prevent them from biting other things at will.
In order to prevent bulldogs from biting, this kind of dog training should also start with puppies. To put it simply, it is necessary to cultivate bulldogs from an early age to develop good living habits and attitudes. Train dogs to develop the habit of "refusing to eat" and not biting casually from an early age. In this way, bulldogs will not bite people when they grow up.
