When Should You Run Functional Gut or Microbiome Testing for Your Pet?
Written by Dr. Katie Woodley, BVSc, cVMA, GDVCHM, CVNN
Last updated: August 6, 2026
The Quick Answer
Functional medicine testing for pets may be helpful when a dog or cat has recurring digestive or skin symptoms, improves only temporarily with supplements, has a history of repeated antibiotic use, or has completed an initial veterinary workup but important questions remain.
Functional gut tests and microbiome tests can provide information about intestinal inflammation, digestive function, immune activity, intestinal barrier markers, and bacterial imbalances. However, these tests do not diagnose every disease and should not replace veterinary examinations, bloodwork, urinalysis, parasite screening, imaging, or emergency care.
If you have a cabinet full of half-used probiotics, digestive enzymes, herbal formulas, powders, and supplements—but you still do not know what your pet actually needs—it may be time to stop guessing.
One of the questions I receive most often is:

Dog Gulping & Licking at Night? Hidden Acid Reflux Signs | The Natural Pet Doctor
The Natural Pet Doctor | Written by Dr. Katie Woodley, DVM (holistic veterinarian)
Quick answer
If your dog keeps gulping, swallowing repeatedly, or licking their lips at night, it can be a quiet sign of acid reflux — even if your dog never actually vomits. Reflux happens when stomach contents move backward into the esophagus, and routine bloodwork usually looks completely normal because it isn’t designed to detect it. The key is to look for a pattern (hard swallowing, lip licking, floor or grass eating, nighttime pacing, gagging, or bringing up small amounts of fluid), track the timing around meals, and start with gentle foundations like smaller meals, a small bedtime snack, and soothing herbs such as slippery elm — while ruling out the red flags that need a vet right away.
Key takeaways
- Reflux can be "silent." A dog may swallow, gulp, or lick instead of vomiting.
- Normal bloodwork doesn’t rule it out. Routine panels don’t test for acid in the esophagus or gut motilit ...

...How To Support Your Pet During a Flare - Vomiting in Dogs & Cats
Flare Tactics: Vomiting in Dogs and Cats
Vomiting is one of the most stressful flare-ups for pet parents to witness, and it’s common to feel overwhelmed or uncertain about what to do next. Here’s a holistic, step-by-step guide to help you confidently support your pet through these moments and advocate for their best care.
1. Pause & Assess
Before jumping in with food, supplements, or medications, the very first thing is to pause. Vomiting is your pet’s body signaling that something is out of balance—this could be a reaction to food, supplements, medications, or even stress. The gut is incredibly sensitive when it’s healing.
- Is this an isolated incident, or has vomiting occurred multiple times in a short period?
- Is your pet still bright, alert, and responsive, or do they seem lethargic and unwell?
- Any other symptoms like diarrhea, blood, or abdominal pain?
- Is there any chance they ate something and have an obstruction?

Histamine Intolerance in Pets: The Hidden Cause of Chronic Itching, Digestive Issues & More
If your pet has been struggling with persistent itching, digestive troubles, or unexplained behavioral changes, you might be dealing with something more than just allergies or food sensitivities. The culprit? Histamine intolerance—a little-known issue that could be affecting your pet's well-being.
Histamine intolerance isn’t a disease but rather a symptom of deeper imbalances within the body.

What is Histamine and Why Does It Matter?
Histamine is a naturally occurring compound that plays a vital role in immune responses, digestion, and even brain function. When your pet encounters allergens or irritants, histamine is released as part of the immune system’s defense mechanism.
