Dog digging is congenital divination. Gen 26: 10 So far, it is a mountain and basalt. Thus, dreaming of being bitten by a dog indicates that something will stop, block and see no light.
However, since I often dream of being bitten by a dog, I can't say that this kind of thing often happens. It should be because of the location of your bed, which means feng shui. There are two possibilities, one is that your bedroom door is in the northwest corner, the other is that the window is in the northwest, and the third is that there are some dolls or sculptures under your bedroom cupboard or bed.
