Could the employer be liable?

Picard was a security guard for National Detective Agency. In violation of company rules, he had his own trained German shepherd dog with him while on duty. Meyers, a passerby, stopped to talk to Picard about the dog, which was in the back of a marked company car. Picard said he could show Meyers how well the dog was trained. When he took the dog from the car, it attacked and injured Meyers. Meyers sued National Detective, which arguedthat Picard’s actions were outside the scope of his employment because he was violating company policy. Could the employer be liable?
Tell me what the court said as to why or why not the employer could be liable in this case.
