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.

There are two types of infection of parvo a dog can acquire, intestinal or cardiac, and the severity varies greatly. Some dogs show no symptoms, yet die within 72 hours. More commonly, in less volatile strains, the mortality rate is just 10%.ymptoms include vomiting, diarrhea, lethargy, fever and a loss of appetite. Dogs with parvo can survive with quick intervention but for some the healing process can be very slow. Many dogs suffer no serious long lasting effects from the virus but there is now a new strain that has been recently discovered.
