Other wormers include dichlorvos, febantel, fenbendazole, ivermectim and piperazine. Hookworms are common parasites of dogs regardless of age. They are most common in warm humid climates but, exist all over North America. Ancylostoma and Uncinaria are the two hookworms found. Both worms are transmitted by chance skin penetration by the immature larvae or by ingestion of contaminated feces.
Hookworm is a zoonotic.
Skin penetration of infective larvae penetrate the bare foot of man and cause mostly a self limiting local skin irritation for three weeks. In the dog hookworm can be severe to unapparent. After eggs are deposited onto the ground in the feces, hot humid temperatures will precipitate the development of larvae. After skin penetration, migration of the larvae into the blood stream carry them around the body and into many tissues. Most are brought to the lungs and like roundworms are swallowed back into the intestinal tract 3 weeks later.
