There are five key parasites that pose a threat to your dog's health. They are fleas, heartworms, roundworms, hookworms and whipworms. These parasites can affect all dogs—not just those who live primarily outdoors. Here's a breakdown of the parasites that can jeopardize the health of your pet:

  • Heartworms. Heartworms can be transmitted to pets by more than seventy species of mosquitoes. And since mosquitoes can get indoors, all dogs are vulnerable. The heartworm larvae develop within the mosquito. When the mosquito bites the dog, it transfuses the larvae into the dog's body tissue. From there, the larvae travel to the bloodstream and continue to develop into adult worms. Adult heartworms live in the right side of the heart and pulmonary arteries where they restrict blood flow and cause organ damage. Blockage and injury caused by heartworms may lead to heart failure and liver and kidney damage. Symptoms include coughing, difficulty breathing, vomiting, weight loss, resistance to exercise, enlarged liver, abnormal lung or heart sounds, collapse or convulsions and sudden death.
  • Fleas. Adult fleas jump onto your pet when they sense a host is near. There, a female flea can lay up to fifty eggs each day. Eggs fall off your pet and develop into worm-like larvae, which hide in carpeting, furniture, bedding and other dark places. The larvae mature as they feed on fecal matter dropped by adult fleas and the cycle continues. Fleas cause itching, irritation, extreme discomfort, and sometimes lead to anemia and flea allergy dermatitis. When ingested, fleas can spread tapeworms. Symptoms of flea infections include itching, scratching and unusual amounts of chewing and licking.
  • Hookworms (A. caninum). Hookworm eggs pass through the feces of an infected dog into the soil where they develop into larvae. The larvae are easily swallowed or can penetrate through your pet's feet. Hookworms attach to your pet's intestinal lining, creating bleeding internal wounds. Symptoms of a hookworm infection include weight loss, anemia and diarrhea.
  • Roundworms. Almost all puppies get roundworms from their mothers. Pets of all ages can contract roundworms from the soil or from eating infected animals, like rodents. Roundworm infections are usually accompanied by symptoms such as diarrhea, vomiting, stunted growth, rough coat and a bloated belly.
  • Whipworms. Whipworm eggs are passed in feces and can survive for years in the soil. Whipworm infections in pets are caused by ingestion of the eggs and usually cause bloody diarrhea, anemia, dehydration and loss of appetite.
