Prevent Hidden Parasites in Your Pet
Internal parasites and infectious diseases can affect pets of all ages, sometimes without obvious signs. Early detection is key to keeping your pet healthy, comfortable, and thriving.
Analysis of your pet’s stool can identify internal parasites (worms) and infectious diseases (Giardia). Some pets acquire them in utero, while others can acquire them through the environment. Often, worms are too small to be visible without the aid of a microscope and lab analysis. We recommend bi-annual fecal testing to ensure your pet’s health, and recommend a monthly preventative such as Interceptor.
Regular fecal testing helps our veterinarians detect hidden infections before they develop into serious health issues, protecting your pet and your family from potential risks.

Why Fecal Testing is Important
Even healthy-appearing pets can carry intestinal parasites. These can lead to weight loss, diarrhea, anemia, and other health problems if left untreated. Many parasites are not visible to the naked eye, which is why microscopic and laboratory analysis is essential.
Bi-annual testing provides a clear picture of your pet’s gastrointestinal health and allows for timely intervention with effective treatments and preventatives.
How We Perform Fecal Testing
- Collection of a small stool sample
- Microscopic and lab analysis to detect eggs, larvae, or infectious organisms
- Identification of specific parasites or pathogens to guide targeted treatment
- Recommendations for ongoing preventive care, including monthly medications such as Interceptor
Preventing Parasites Long-Term
Fecal testing is most effective when paired with a consistent parasite prevention plan. We advise monthly preventatives to protect against common worms and other gastrointestinal parasites, while routine testing helps catch any breakthrough infections early.
Early detection and prevention are key to your pet’s long-term health. If it’s been more than six months since your pet’s last fecal test, contact Greenwood Lake Animal Hospital today to schedule a screening.
