Gut Health Test

How fresh does the poop sample need to be for analysis?

For dogs, we recommend collecting a sample as soon as your dog poops, picking it up in a bag, and bringing it to your sampling area right away. For cats, the sample should be less than 8 hours old.

Do I need to discontinue supplements or medications before taking a poop sample for analysis?

When possible, we recommend discontinuing antibiotics and probiotics at least 24 hours before taking a poop sample for analysis.

My pet is having diarrhea. Can I still send a poop sample for analysis?

Yes. Our test has been carefully optimized to account for loose stool or diarrhea. When you collect the sample, try to cover as much of the swab tip as you can, and be sure to break off the swab tip and leave it inside the tube.

Will my pet's sample be safe in the mail?

The sample tubes included in the test kit contain a special preservative that keeps the bacteria in your pet’s sample well protected at a wide range of temperatures for up to a year. We have received, and successfully analyzed, fecal samples shipped from 6 of the 7 continents. We recommend sending the tube(s) soon after you collect a sample, but the sample will be safe during transit.

Gut Restore Supplement

What is the Gut Restore Supplement?

The Gut Restore Supplement (fecal transplant in a capsule) provides a whole community of healthy cat- or dog-specific microbes that are sufficient to build a healthy microbiome and restore balance.

Why are some of my Gut Restore capsules different shades of brown?

The Gut Restore Supplement is a natural product that is gently preserved and processed. Small variations in diet, hydration status, or activity can result in capsules that are slightly different colors from one another.

Do the Gut Restore capsules need to be given whole, or can I break them open and mix them with food?

Whenever possible, the capsules should be given whole, and should not be opened. This is because the outer capsule has an acid-resistant coating that protects the bacteria during their journey through the stomach. Without the outer capsule as protection, the bacteria may die in the stomach.

When is the best time to take an oral sample from my dog?
