White blood cells are attacked and can damage the heart muscle causing long-term heart problems. It can be transmitted through anything that has come into contact with the feces of an infected animal, including people, animals and objects. It is very resistant and can live for months outside the body, on food bowls, clothing, furniture and floors. Unvaccinated dogs can easily contract the virus by walking on the streets. The dog will appear lethargic and have a loss of appetite. There will be severe vomiting and diarrhea, which can cause severe dehydration. (petmd, 2013) Hookworm Hookworm is an infectious intestinal parasite. The eggs are expelled from the body through feces and hatch in warm, humid conditions. Factors that influence parasite transmission include larvae that penetrate the animal's coat, can be ingested directly while the dog licks and grooms itself, larvae that migrate directly through the skin, and the dog eating a hookworm-infested rodent.
