Addiction is a chronic brain disease that induces compulsive activity, despite health, social and legal consequences. A person may seem to make a voluntary choice to try a drug or begin a type of behavior, but a variety of genetic and environmental factors influence those decisions.

As with humans, advanced years often bring changes in a dog's ability to hear, see and move about easily. Skin condition, appetite and energy levels often degrade with geriatric age, and medical conditions such as cancer, renal failure, arthritis and joint conditions, and other signs of old age may appear.he mean age at death (all breeds, all causes) was 11 years and 1 month, but in dogs dying of natural causes it was 12 years and 8 months. Only 8 percent of dogs lived beyond 15, and 64 percent of dogs died of disease or were euthanized as a result of disease.
