If you didn't have intimate contact with the dog a few days before your dream, that is to say, the scenes in your life didn't come out in your dream, then according to the Duke of Zhou, it is not good to dream that the dog bites people, so you should pay more attention, for example, to avoid quarreling with colleagues, friends and even strangers, especially to avoid contact with people who have their own festivals recently, so as to avoid conflicts. In terms of money, we should use it carefully and think twice about unnecessary or unknown expenses. If the dog bites its foot, try not to go far in the near future and pay attention to its own safety.
But you can't say for sure about this. Maybe it's nothing at all. Don't trust your dreams too much.
