If a dog bites another person, the dog breeder has the corresponding responsibility. According to Chinese laws, as an animal breeder, the owner should bear the tort liability. However, if the dog bites the other person deliberately flirts with the dog and has gross negligence, the owner can mitigate or not bear the liability. However, if the dog you raise is a fierce dog, you should bear the liability for infringement regardless of whether the other party has intentional or gross negligence.
 If a dog bites a person, the owner has to bear the following expenses: medical expenses, nursing expenses, transportation expenses and other reasonable expenses for treatment and rehabilitation, as well as reduced income due to missed work. If it causes disability, it shall also compensate for the cost of disabled living aids and disability compensation. Among them, if the mark of a dog biting another person does cause a scar to the other person, then the beauty fee paid by the other person to treat the scar should also be paid. However, there is no legal basis for the other party to request payment of mental damages, and you can refuse to pay.
 Although the other party was bitten by a dog, the other party's expense claim also has a scope, and has no right to claim payment of mental damage compensation, and the following expenses that the other party requires you to pay must be supported by invoices. If the other party spent beauty money to eliminate the scar left after the dog bite, the other party should also submit evidence to prove.
