    Why Understanding Hookworm Lifecycle in Dogs is Elemental to
    Treatment and Eradication
      
    Hookworms are considered to be the most pathogenic of all canine and feline parasites
    including roundworms and dog tapeworm.

    Hookworms are excessively greedy blood suckers and cause extensive loss of blood.
    They ‘hook’ on to the walls of the intestines and draw out blood and ingest it directly.
    Some can bite and cause lacerations which result in blood leaking. To add to the
    miseries, the esophageal glands of the hookworm secrete an enzyme that inhibits
    blood coagulation.

    Hookworms can penetrate skin and infect humans as well. Barefoot humans and
    children who play in areas where dogs defecate are at a high risk of infection. A
    study of the lifecycle of hookworms can go along way in achieving the goal of
    treating hookworm infection and eradication of hookworms from the environment.

    Depending upon the species, an adult hookworm can lay up to thirty thousand eggs
    in a day. A moist loamy soil and warm temperatures are most conducive to hookworm
    survival. But these hardy parasites have been known to survive in tougher climatic
    conditions also. Unlike other worms in dogs hookworms develop in feces only when
    the feces are broken up naturally by earthworms or rain. Larvae in their infective stage
    move out from the feces and wait in the soil or vegetation for a host to pass by.

    Hookworms enter a dog’s body and move on to the intestines in different ways.

    The dog can get infected by ingesting larvae directly from the soil or by preying on
    infected hosts like rodents and mice.

    Puppies can get infected through mother’s milk during nursing.

    Some hookworm parasites can penetrate the skin tissue and bore through tissues till
    they migrate through blood vessels or lymphatic duct to ultimately arrive in the lungs.
    From there they penetrate the capillaries, through bronchioles, bronchi, and trachea
    and finally into the pharynx. The dog coughs and swallows the larvae and they travel
    through the digestive tract to the small intestines.

    Larvae that are ingested reach the small intestines directly through the digestive tract.
    Once in the intestines they shed the outer skin and grow into adult hookworms. Adult
    hookworms can live in a dog’s body from two months to two years, causing some of the
    most serious symptoms of worms in dogs like severe anemia. Severe hookworm infection
    can cause death by reducing the protein levels in a body. Severe anemia in puppies and
    dogs can also result in death.

    Depending upon the age of the dog, eggs are again excreted in a dog’s feces after
    fifteen days to a month. Only a small percentage of eggs mature in the environment.
    In some cases the host is resistant to hookworm larvae. In such cases they may move
    through the body without ever reaching the small intestines.

    Prevention and sanitation of the environment and regular de-worming regimes is the
    only method of controlling and treating hookworms, which are sometimes termed as
    “carnivore hookworms”.
