The onset and severity of disease in the pet is principally a manifestation of the number of adult heartworms present, the age of the infection and the level of activity of their dog. Dogs with high numbers of worms are usually found to have more severe heart and lung disease affects. Until the amount of adult heartworms exceeds 50 at a 25-kg dog (approximately 55 pounds), nearly all of the heartworms reside in the lower caudal pulmonary arteries (the blood vessels of the lower lung lobes). Greater quantities of heartworms lead to their own existence in the right chambers of the heart. In such ailments, the most frequent early pathological changes brought on by heartworms are due to inflammatory processes that exist in and around the blood vessels of the lower part of the lungs in response to the presence of heartworms. Later, the heart may enlarge and become weakened due to an increased workload and congestive heart failure may occur. An extremely active puppy (e.g., working puppy ) is far more likely to develop serious disease with a comparatively few of heartworms than an inactive one (e.g., a lap dog or couch potato). On occasion, a dog with a large number of heartworms might not just have worms at the center, but also from the caudal vena cava (large primary vein of the body) involving the liver and the center. If the heartworms aren't removed surgically, this syndrome causes sudden collapse and death within two to three times.Canine heartworm disease is widely distributed throughout the United States. Heartworm infection has been observed in dogs indigenous to all 50 states. All dogs, irrespective of their age, gender, or habitat, are susceptible to heartworm disease. The maximum infection rates (around 45 percent ) in dogs (not maintained on heartworm preventive) are observed in 150 miles of the Atlantic and Gulf coasts from the Gulf of Mexico to New Jersey and across the Mississippi River and its major tributaries. Other areas of the United States might have lower prevalence rates (5 percent or less) of canine heartworm disease, while some regions have ecological, mosquito population and pet population factors that allow a greater neighborhood incidence of heartworm disease. Regions where heartworm disease is prevalent have diagnosed infections in puppies as young as one year of age, with most areas diagnosing infections primarily between the ages of three and eight decades. Although there are differences in frequency of disease for various groups of dogs, all dogs in most areas should be considered at risk, put on prevention programs and also often examined by a veterinarian.
