A Chow Chow with a gentle face may occasionally show abnormal behaviors, such as lunging or even biting owners and family members. This can cause resistance toward the dog by the owner and is very dangerous if it persists long-term. So, typically, what are the common reasons and handling methods for pet Chow Chows biting their owners:

　　First, food guarding: Chow Chows will attack approaching conspecifics or humans to protect their food from being taken away. If the dog has a food guarding tendency, the owner should avoid getting close or petting while it is eating to prevent attacks or biting caused by food guarding.

　　Second, protecting puppies: Nursing mothers often bite owners or family members; this behavior is to protect their puppies. This is maternal instinct. Owners should avoid making sudden movements when approaching puppies during nursing and try to avoid triggering the mother dog's aggression. If the mother dog is strongly defensive, protective measures such as isolating the mother dog should be taken when caring for puppies.

　　Third, fear and pain: Chow Chows may also bite owners when scared or nervous, such as during baths, administering medicine, or being scolded or hit by the owner. This is an animal's natural instinct and a reaction humans also have when feeling threatened. Avoid hitting or scolding the dog; owners can use bite-proof muzzles or anti-bite gloves.

　　Fourth, territory defense: Dogs also have a concept of territory or turf. Some dogs dislike family members or owners approaching their territory and will attack when approached. Avoiding territorial behavior is a way to prevent them from biting.

　　Fifth, playful biting: Many people find dogs like to lightly bite their hands; this is not aggression but a form of play. If the Chow Chow's bite does not hurt the owner, it is generally not a problem; but if the bite is very hard, prevention is necessary. You can buy chew toys or dog bones for the dog to play with.

　　Besides the above reasons, there are other causes. However, the owner must carry out corrective training or preventive measures. Early correction of biting behavior gives family members and others more assurance. After all, dogs biting people is a very serious matter.
