Microbiome Testing for Pets

Why your pet’s gut health matters — and how testing helps

What is the microbiome?

Your pet’s gut is home to trillions of microbes (bacteria, fungi and more). Together, they help digest food, make vitamins, train the immune system, and keep the gut lining healthy. When this ecosystem is out of balance (called dysbiosis), pets are more prone to intestinal troubles, skin problems, and other inflammatory conditions. Chronic conditions, including cancers, may be triggered or directly impacted by gut microbiome imbalances.

Why test the microbiome?

• Find the imbalance: Find out which microbes are high, low, or missing. This allows for targeted treatment.
• Guide care: Results can inform treatment interventions, including diet, supplements, and restorative therapies.
• Track progress: Re-testing shows whether changes are helping over time.

Why antibiotics often aren’t the long-term answer

• Metronidazole (often given in cases of diarrhea) disrupts the microbiome for weeks or much longer and doesn’t consistently improve long-term outcomes; recent work shows similar (or better) clinical results with microbiome-friendly options like microbiome restorative therapy (FMT - Fecal Microbiota Transplantation).
• Microbiome restorative therapy/Fecal microbiota transplantation (FMT) can help some chronic cases - not just cases of diarrhea, but also chronic itchiness and other inflammatory conditions.
• In dogs with hard-to-treat chronic enteropathy, 31 of 41 dogs (≈76%) improved clinically when FMT was added (better stool quality and/or activity level). That suggests FMT can be a useful adjunct in some cases as well. PubMed

How I use your pet’s results

1. Review: Which microbes are low/high? Any red-flag patterns?
2. Plan: Is microbiome restorative therapy indicated? What other lifestyle, supplement or diet strategies are important for long term health?
3. Recheck: After evaluating clinical improvement, we may consider a follow-up test to confirm progress within the microbiome itself.

And the best news - all this can be addressed from the comfort of home, including testing and treatment. Email me at consultaholisticvet@gmail.com to schedule a consultation and get your pet's gut back in balance for the betterment of their overall health!
