Ancylostoma species, Hookworm

Ancylostoma species are hookworms that can be detected in stool. They are intestinal worms and are not considered a normal part of the dog’s gut microbiome. Dogs may be exposed by swallowing hookworm larvae from contaminated soil, sand, grass, dog parks, kennels, or other areas where infected faeces may have been present, especially warm, moist, or shaded ground. Some larvae can also enter through the skin. Hookworms mainly live in the small intestine, where they attach to the intestinal lining and feed on blood. This can irritate the gut and may be associated with blood loss, especially in puppies, young dogs, or dogs with a heavier infection. Relevant findings may be associated with diarrhoea, dark or bloody stools, weight loss, reduced appetite, weakness, pale gums, poor coat condition, or signs of anaemia. A positive finding may be useful to review with a veterinarian, especially if digestive signs, possible exposure to contaminated ground, dark or bloody stool, pale gums, weakness, or other signs linked to blood loss are present.
