If your puppy continues to bite even after training, it can be frustrating and concerning. Here are some steps you can take to address the behavior:

1. Determine the cause of the biting: It is important to understand why your puppy is still biting. It could be due to a lack of consistency in training, boredom, frustration, or anxiety. Once you determine the cause, you can take steps to address it.
2. Continue training: Consistency is key when it comes to training. It may take some time for your puppy to learn to control their biting behavior, and it is important to continue reinforcing good behavior and redirecting them when they start to bite. Be patient and consistent in your training efforts.
3. Provide plenty of exercise and mental stimulation: Puppies need plenty of exercise and mental stimulation to keep them occupied and prevent boredom. Make sure your puppy is getting enough physical exercise and provide plenty of interactive toys and puzzles to keep them mentally stimulated.
4. Avoid rough play: Playing rough with your puppy can encourage biting behavior. Instead, use gentle play and redirect them to appropriate toys when they start to bite.
5. Use positive reinforcement: Positive reinforcement is a powerful tool in training. Reward good behavior with treats, praise, and attention. This will help your puppy understand what behaviors are expected of them.
6. Seek professional help: If your puppy’s biting behavior is persistent and severe, it may be necessary to seek professional help from a certified dog trainer or behaviorist. They can help to identify the underlying cause of the biting behavior and develop a customized training plan.

It is important to remember that addressing puppy biting behavior requires patience and consistency. With time, effort, and proper training, your puppy can learn to control their biting behavior and become a well-behaved, happy dog.
