Opinion 1: Lawyer Han Bing from Sichuan Yafeng Law Firm: The villa is in a closed state, and the victim illegally intruded into the private residence by climbing over the wall, bearing the initial fault; the dog owner was not at home and could not control the dog's behavior; the thief's injury was mainly caused by their own theft and escape attempt, and they should bear full responsibility for this incident. The dog owner bears no civil liability and is without any fault. If the dog owner was at home at the time of the incident and did not stop it in time, the dog owner will bear the corresponding civil liability; if the dog owner actively incited the dog to cause injury, the dog owner will bear the corresponding criminal liability.
Opinion 2: Lawyer Song from Sichuan Zhouji Law Firm: Regardless of whether the dog owner is at home, the owner should be responsible for managing the dog. In this case, the dog owner is obviously negligent in management and should bear the corresponding civil compensation liability. Given that the victim illegally invaded a private residence with significant fault, the dog's owner's compensation amount should be relatively reduced.
