What Can Roundworms Do to Dogs?

Roundworms are a type of parasitic worm that can infect dogs and cause a variety of health problems. These worms are transmitted through the ingestion of infected feces, contaminated soil, or infected prey, such as rodents.

Here is a list of what roundworms can do to dogs:

  1. Intestinal blockages: Roundworms can cause intestinal blockages, which can lead to abdominal pain, vomiting, and diarrhea. If left untreated, these blockages can be life-threatening.
  2. Anemia: Roundworms can cause anemia, which is a condition where there is a deficiency of red blood cells. This can lead to lethargy, weakness, and difficulty breathing.
  3. Weight loss: Roundworms can cause weight loss due to malnutrition. This is because the worms consume nutrients that would otherwise be absorbed by the dog.
  4. Stunted growth: In puppies, roundworms can cause stunted growth and development. This is because the worms consume nutrients that are essential for proper growth and development.
  5. Ingestion of roundworms: Humans can also accidentally ingest roundworms if they come into contact with infected feces or soil. This can lead to a condition called visceral larva migrans, which can cause fever, abdominal pain, and eye abnormalities.

To prevent roundworm infections, it is important to keep your dog’s environment clean and free of feces, to practice good hygiene when handling your dog, and to regularly deworm your dog. If you suspect that your dog has roundworms, consult with a veterinarian for treatment. Roundworms can be transmitted to humans, so it is important to take precautions to prevent infection.
