Beagles may bite more and more because they are angry or fearful and want to protect themselves. Generally, Beagles will bite and attack when they are angry. If you use hitting them to solve the problem, they will only make them angry. More anger and fear, if the dog cannot be tamed by violence. If the dog makes a mistake, you can reprimand it loudly. When the dog behaves well, reward it with snacks or petting. Only when rewards and punishments are clear will the dog develop good habits.
