Use gloves to place the feces in plastic bags and discard in your trashcan. Hookworm larvae can survive weeks in cool, moist soil but will not survive long in extremely cold or warm, dry temperatures. Since the dog's environment can be infested with hookworm eggs and larvae, it is critical that you remove any feces from your yard promptly. In rare cases, a blood transfusion may be necessary in dogs with severe anemia. Therefore, it is necessary to treat an infected dog again in about two to four weeks to kill any newly developed adult worms that were larvae at the time of the first treatment. 'It is necessary to treat an infected dog again in about two to four weeks to kill newly developed adult worms.' However, these drugs only kill the adult hookworms. Most are given orally and have few, if any, side effects. There are several effective drugs, called anthelmintics, which will eliminate hookworms. For this reason, fecal examination may be less reliable in very young puppies than in adult dogs.Īdult hookworms are small in size and firmly attach to the intestinal wall, which is why they are rarely detected in stool. It takes 2-3 weeks for hookworm larvae to mature and begin producing eggs. 'Hookworms are diagnosed with a microscopic examination of a stool sample.' Dogs may also exhibit coughing in severe cases. It is not uncommon for young puppies to die from severe hookworm infections. Some dogs experience significant weight loss, bloody diarrhea, dull and dry hair coat or failure to grow properly with hookworm infection. Pale gums and weakness are common signs of anemia. Therefore, the dog can suffer blood loss from the hookworm’s feeding, as well as continued bleeding into the bowel from the attachment sites, causing anemia. This can cause continued bleeding after the hookworm has detached from the feeding site. The parasites anchor themselves to the intestinal lining so that they can feed on tissue fluids and blood, injecting an anti-coagulant substance which prevents the blood from clotting. The most significant clinical signs are related to intestinal distress and anemia. What are the clinical signs of hookworm infection? Prenatal and transmammary infections are an important route of infection for puppies. Puppies may also become infected after birth through mother's milk ( transmammary) during nursing. If a pregnant dog had hookworms in the past, the pregnancy may reactivate dormant larvae, which then enter the female's bloodstream and infect the puppies in the uterus ( prenatal infection). 'Prenatal and transmammary infections are an important route of infection for puppies.' Part of the life cycle of the hookworm involves migration through muscle tissues, where they may become dormant (alive, but temporarily inactive). The dog will then cough up and swallow the larvae which then migrate to the intestinal tract, where they mature and complete their life cycle. Once in the host's body, the larvae migrate to the lungs and trachea.

The larvae may also burrow into the skin if the dog walks or lies on contaminated ground. A few larvae may make their way into the trachea (windpipe), and are then coughed up and swallowed.

Most larvae that are ingested will move to the intestinal tract to complete their life cycle. A dog may become infected when it inadvertently swallows hookworm larvae, often by grooming its feet, or from sniffing feces or contaminated soil. Larvae hatch from the eggs and can remain infective in the soil for weeks or months.

through the mother's placenta before birth ( in utero)įemale hookworms pass hundreds of microscopic eggs in the feces of infected dogs, where they contaminate the environment.Conditions of overcrowding and poor sanitation contribute to infection.ĭogs may become infected with hookworms by one or all of four routes: Hookworms are more common in warm, moist environments. Anemia is most common in puppies, but can occur in adult dogs.Īre some dogs more likely to get hookworms? A large number of hookworms can cause inflammation in the dog’s intestine, as well as a life-threatening decrease in the number of red bloods cells (called anemia).

Despite their small size, they ingest large amounts of blood from the tiny blood vessels in the intestinal wall. They are only about 1/8' (2-3 mm) long and so small that it is very difficult to see them with the naked eye. Hookworms ( Ancylostoma caninum, Ancylostoma braziliense, Uncinaria stenocephala) are intestinal parasites of the cat and dog that get their name from the hook-like mouthparts they use to anchor themselves to the lining of the intestinal wall.
