Since they are in the phylum Nematoda, hookworms have a psuedocoelom that they use for digesting food. -Hookworm eggs gain nutrients via the feces of the host that it has inhabited. -In the larval stage, hookworms are free-living in the soil.
Dogs get infected with hookworms by ingesting contaminated sources that contain hookworm or roundworm larvae. Hookworm larvae pass through the dog's skin and migrate to the intestines to form adult hookworms. Pregnant pets may transmit the larvae to their unborn puppies through placental blood flow.
