Dog Poop Parasites: What Owners Should Know

Roundworms

Roundworms are one of the most common parasites found in dog waste. Adult dogs can carry roundworms without showing any symptoms, and the eggs pass out in their stool. Once in the soil, the eggs are remarkably durable. They can survive for months, and in some cases longer, waiting for a host.

If a child accidentally swallows soil containing roundworm eggs, the eggs can hatch inside the body. The larvae can then migrate through tissues, a condition that can cause serious health problems. This is rare, but it is a real risk in yards where dog waste has been left to decompose.

Regular deworming of your dog, as recommended by your veterinarian, reduces the risk of roundworms in their waste. But even a dewormed dog can occasionally shed eggs, so removing waste promptly is still essential.

Giardia

Giardia is a microscopic parasite that lives in the intestines of infected animals, including dogs. It is shed in waste as cysts, which can survive in cool, moist soil for extended periods. If a person or animal ingests giardia cysts, they can develop giardiasis, an infection that causes diarrhea, cramping, and nausea.

Giardia is particularly concerning because it can spread through contaminated water as well as soil. In a yard where dog waste has been left to decompose, rain can wash giardia cysts into puddles, storm drains, and nearby streams.

Dogs can carry giardia without showing symptoms. Your veterinarian can test for it and recommend treatment if needed. But the most effective prevention is removing waste before the cysts have a chance to enter the environment.

Hookworms and Other Parasites

Hookworms are another parasite found in dog waste. The eggs pass out in stool and hatch in the soil. The larvae can then penetrate bare skin, which means walking barefoot in a contaminated yard can lead to infection. Hookworm larvae can survive in warm, moist soil for weeks.

Other parasites that can be present in dog waste include whipworms and coccidia. Each has its own life cycle and survival characteristics, but the common thread is that they all spread through contaminated soil. The longer waste sits, the more time parasites have to enter the environment.

For specific concerns about your dog's health, speak to your veterinarian. They can recommend a parasite prevention plan tailored to your dog and your area.

How to Protect Your Family

The single most effective step is to remove dog waste from your yard weekly. When waste is removed before it has time to decompose, the parasites do not have a chance to leach into the soil. The yard stays clean, and the risk of exposure drops dramatically.

If your yard has already been contaminated, a one-time cleanup removes the source. After that, weekly service keeps the problem from returning. You can also read about how dog poop can be dangerous to kids for more on the specific risks to children.

Have your dog checked regularly by a veterinarian and follow their parasite prevention recommendations. A healthy, dewormed dog produces safer waste, but even then, prompt removal is still the best practice.
