Have you ever considered that some other aspects of your, your mother and your dog's lives could be counteracted by a large number of other factors, such as earth energy (check with Feng Shui, Dowsing), nutrition, prescription drugs or herbal remedies, etc? No matter how good you are as an energy therapist, if other forces are going against you, you will not see an improvement. Have you considered methods which allow you and your mother to let go of the past, eg Natural Brilliance, Sedona Method, etc? Have you looked at detoxification?
