Now we get these parasites when a mosquito bites us and the larvae get under our skin. Then they molt for 3 to ten days, then they molt a second time for 55 to 70 days. Three months after that the worms mate and start all over again. There are literally millions of larvae and eggs in an infected puppies blood. I guess thats how they got there name.
Young puppies are in the most danger but they can kill older puppies too by eating all the blood.
The eggs of the Hookworm passes through the infected animal in the feces. Then turn into larvae and are swallowed by another puppy or gain entry through the foot pads. Mother's can give hookworms to her pups through the milk. Worms I mean not guts. If I accidentally eat an infected flea that I been biting at, I will get tapeworms.
