In addition to heartworms, dogs and puppies are also at risk for dangerous intestinal worms. Roundworms and hookworms are common intestinal parasites that cause serious health hazards.

Roundworms

Roundworms are parasites that live in the intestines of infected dogs, depriving dogs of essential nutrients and possibly causing obstructions. Infections may be dangerous or even fatal. Signs of roundworm infection may include diarrhea, respiratory distress, weakness, dull and scruffy coat, swollen abdomen, and malnutrition. However, it is important to note that most dogs show no signs of infection.

Roundworms may be transmitted to puppies even before birth, or an infected mother can pass roundworms to her puppies after birth through her milk. Roundworms also may be transmitted when a dog or puppy consumes roundworm eggs in its environment.

Hookworms

Hookworms, like roundworms, are parasites that live in the intestines of infected dogs. They feed on the intestinal wall, causing significant blood loss. Though not as common as roundworms, hookworms are potentially more dangerous, especially in puppies. Severe hookworm infection can lead to anemia, debilitation, and even death. Signs of hookworm infection may include weakness, weight loss, diarrhea and pale gums. As with roundworm infection, most dogs infected with hookworms will show no sign of infection.

Hookworms may be transmitted to puppies while still in the womb, or to nursing puppies through infected milk. Hookworms also may be transmitted to puppies and older dogs through materials in the environment that may be contaminated with larvae.
