This dream suggests that the dreamer is running away from trouble. If this is a recurring dream, it indicates that the dreamer is avoiding a problem in real life. It is time to stop running away and face the difficulty directly so it can be resolved.
---- It means that bad luck is chasing you.
bad luck
i do not want to be the bearer of bad news but a black dog normally signifies death
a bee?
I once heard that black dogs in dreams represent the devil and that if you dream of them it could mean you are headed in the wrong direction in life. Since the dog bit an employee it could have meant it was time to get rid of her.As for your son shooting the dog that could just be your own imagination.
Dogs dream about anything, just like humans. Often I will catch my dog running or barking in his sleep.
that you have a very vicious dog
This appears to be a dream about invisible (imperceptible) limitations. The dog is confined by an electronic "invisible fence," a common device used when actual fencing is not desirable or possible. It is a metaphor for some sort of subtle limitation the dreamer feels imposed on his/her life.
Try to get your dog away from the other dog chasing it OR try shooing away the dog chasing your dog OR they might just be playing "chase"
Chasing the cat.
It means nothing. It just means that in your dream the world exploded.
In many old cultures, a black dog represents death. So a dog that turns from black to tan is becoming less dangerous. The dog itself is a metaphor for something with similar qualities in the dreamer's real life. For example, if the dreamer is "dogged" by poor health, then the dream suggests that health is improving. See link for more info on dreams and metaphors.
Not unless the dog is changing speeds. If the dog is chasing the cat at a constant speed it is not an example of acceleration.
