Dog Hookworm (Ancylostoma caninum)

….a species of hookworm restricted to temperate, tropical and sub-tropical regions worldwide. A.caninum typically infect dogs and other canids and can cause serious damage. Like other hookworms A.caninum is transmitted via feces, as the larvae grow there. If the larvae gain contact with a host they will penetrate the skin and make their way to the lungs. Once in the lungs they will ascend into pharynx and are swallowed. They will settle in the lower intestine, where they will attach to the intestinal wall and mature into adults. Eventually they will mate and their eggs will leave the body via excrement.

Dog hookworms can cause major damage to the intestines and should be treated if contracted.
