Hookworms are parasites found in soil that are often ingested by dogs or burrow into the skin through the paws when the animal digs around in the dirt. They can also be passed to puppies from the mother's milk. Once inside the stomach of a dog, the hookworm passes into the small intestine where it hooks onto the walls and feeds on the blood. The parasite then develops into an adult and lays eggs. The eggs will pass through the animal's digestive system and are excreted with the feces. Hookworms can be quite dangerous to your pet and cause specific signs such as anemia, black and tarry stools, dry and dull fur and, in some cases, pneumonia.

Anemia
-
Anemia is one of the most common signs of hookworms. Puppies are the most susceptible to hookworms, and the anemia will cause a lack of energy, lethargy, and will often cause the animal to collapse without any reason. The gums of the animal will also appear to be very pale. If your puppy exhibits any of these symptoms he requires immediate care from a veterinarian, who will not only treat the anemia but also the hookworm infestation.
Pneumonia
-
Pneumonia can also be a sign of a hookworm infestation in your dog, and it is often overlooked. The larvae from the hookworms often migrate into the lungs, causing the infection, and sometimes the only symptom of the pneumonia is a cough. The dog will become extremely weak and emaciated, and if not treated, this will eventually lead to the animal's death.
Other Signs
-
Some other signs that your dog has become infected with hookworms include black and tarry feces, vomiting and diarrhea, stunted growth in puppies, and fur that seems to be dry, brittle and dull in appearance. If your pet exhibits any of these signs it is recommended that you seek assistance from a veterinarian for proper diagnosis and treatment.
