Malicious biting is a bad habit, which happens to many bichon puppies because they don't get enough opportunities to grind their teeth. In order to change this bad behavior, we need to take the following measures:

First of all, the owner should ensure that the dog has enough exercise and play time, and provide the dog with suitable toys and grinding sticks, so that the dog can vent its energy and overcome anxiety, thus changing the dog's bad habits.

Secondly, the host can also use positive reinforcement methods to reward his good behavior, such as sitting down and shaking hands. At the same time, the owner should make clear rules and restrictions on dogs to avoid inappropriate behavior, which will help to establish a good relationship and order.

Finally, if this situation persists, the owner should consider seeking professional help, such as consulting a pet behavioral therapist or dog trainer. With their help, they can design and implement a behavior training program to help dogs get rid of bad habits such as biting.

In short, the owner should take appropriate measures to solve the problem that Bixiong puppies want to bite. In the process of establishing the training plan, we should not only pay attention to the correctness and effectiveness of the methods, but also strengthen the management and attention of dogs to help Bixiong puppies grow up actively and healthily.
