While guide dogs are not specifically trained to disobey commands, they are trained to use their own judgment to keep their owners safe. This means that they may sometimes ignore a command if they believe that it is not in their owner's best interest. For example, if an owner gives their guide dog a command to cross a street, but there is a car coming, the guide dog may choose not to cross until it is safe to do so.
Guide dogs are highly intelligent animals that are capable of learning a great deal. They are trained to be obedient, but they are also trained to be independent thinkers. This combination of obedience and independence makes guide dogs invaluable companions for people who are blind or visually impaired.
