Dog Intestinal Parasites The Canine Hookworms

There are two kinds of canine hookworms that infects the dogs – Uncinaria stenocephala and Ancylostoma caninum.

In the case of parasite roundworm infections, dormant hookworm larvae can be activated in pregnant female dogs, and transmitted to puppies through the placenta or through their mother’s milk.

Dogs can also be infected accidentally by eating hookworm eggs and larvae.

Parasite infection can also occur through the larvae penetration of the skin or the lining of the mouth.

The life cycle of canine hookworms in dogs

When hookworm larvae penetrate the skin, these parasites are carried by the blood to the lungs. The larvae are coughed up and then swallowed to establish residence in the small intestine.

When a dog eats larvae, some of them may migrate through the lungs, but most of the parasites only penetrate the intestinal wall. A few days later, they return to the gut, where they will mature into adults.

Like roundworms, adult canine hookworms produce eggs that are expelled in the feces of infected dogs, and thus contaminate the environment.

Hookworm eggs survive well in mild temperatures, shade and moist soil or grass.

Although direct sunlight, drying out and freezing will destroy most hookworm eggs, there are still some are extremely resistant to cold temperatures.
