Other individuals are bolder, tunnel out of the intestine, and migrate to the lung tissue. Once the larvae are inside the host, they make their way to the intestine where some worms simply stay and mature into adulthood. Another way for the larva to gain entry to the new host is to be present in soil that is licked and swallowed by the host as it cleans itself.
FELINE HOOKWORMS IN HUMANS SKIN
One way is to penetrate the host's skin directly through the feet or belly or whatever part of the skin is touching the ground. The larva can infect its new host in several ways. The egg hatches in the environment and develops from a first stage larva (the hatchling) to a second stage larva and finally a third stage larva, which is ready to infect a new host. Hookworm eggs are released into the intestinal contents and passed into the world mixed in with the host's stool.
The adult worm lives and mates within the host and ultimately, the female worm produces eggs. This means that, like other parasitic worms, they are bathed in intestinal contents but while other worms share the host's food by absorbing it directly through their skin, hookworms feed by drinking their host's blood. It hangs on to the intestinal wall using its six sharp teeth.
The adult hookworm lives in the small intestine of its host.

Hookworms can be transmitted to unborn pups.Hookworms (particularly Ancylostoma caninum) suck blood.Hookworm infection has several features that are of interest to the caretakers of dogs: Hookworms ( Ancylostoma caninum, Ancylostoma braziliense, Uncinaria stenocephala) are one of the classical internal parasites of puppies, the others being roundworms, tapeworms, and coccidia.
