For some people a dog was the only source of expressive love in their childhood, so may well depict this. Dor on lead: restrained or controlled urges.
The dog appears more often than other animals in dreams.
Example: I continue on my path, and suddenly the nettles disappear and the path is clear. Ahead the wall has curved round to face me, hut there is a gate in it, and I can see my dog waiting for me on the other side’ (Mrs MG). In the dream of this elderly woman the dog is leading the way through the experience of meeting death. Mythology has often shown the dog in this light, as an inner sense of knowing how to find transformation through death—or as the ravaging threat of death. Idioms: die like a dog; dirty dog; dog eared; dog eat dog, dog in the manger, gay dog; go to the dogs; let sleeping dogs lie; etc.
