Once your order ships, you will receive a shipping confirmation email with tracking information. Please note that shipping times may vary depending on the destination, carrier, and any customs processing for international orders.
Tracking may not update every day while a package is in transit. A lack of movement for 1-2 days is often due to a missed carrier scan, and the package is likely continuing to move through the shipping network.
Please continue to monitor your tracking information. If your tracking information has not been updated by the end of the expected delivery window, please contact us with your order number so we can review the shipment status.
We ship to a growing number of international destinations. Because shipping availability can change based on carrier service, product type, and country-specific import rules, the best way to confirm availability is at checkout.

Customs processing times vary by country and are unfortunately not within our control. We encourage you to your tracking information and respond promptly to any requests from customs or the carrier.

In the meantime, please check around your front door, porch, side door, garage, mailbox, and any hidden delivery areas. We also recommend checking with household members, neighbors, and your apartment office, mailroom, front desk, or building manager, if applicable.
If it has been more than 2 business days since the package was marked delivered and it still has not arrived, please contact us with your order number, complete mailing address, and the steps you have already taken to locate the package. We’ll review the tracking details and help determine the next best step.

Sample Collection & Kits
There is no need to refrigerate or freeze your sample.
Gut microbiome samples contain a specially formulated preserving liquid that helps keep the bacteria stable during transit, even when exposed to hot or cold temperatures. Oral microbiome samples do not require a preserving liquid to remain stable.
The Gut Microbiome Test includes everything you’ll need to collect a small sample of your pet's stool, including detailed instructions.
For best results, we recommend discontinuing probiotics for 24 hours before collecting a sample.
• Collect a fresh stool sample (within 4 hours of elimination for dogs, or first thing in the morning for cats).
• Use the swab in your kit to place a pea-sized piece of fresh stool into the tube.
• Seal the tube and follow the instructions to mail the sample back to our laboratory.
Tip: When possible, keep litter, grass, and other debris out of the sample.
For US Returns:
Place the ziplock bag with the sealed collection tubes into the provided mailer, and drop it off at the appropriate shipping location.
Test kits purchased on or before May 31, 2026 are returned via FedEx.
Test kits purchased June 1, 2026 and later are returned via USPS.
For International Returns:
Complete instructions were shipped with your International Gut Microbiome Test. You can return via the carrier of your choice.
Reach out to our team if you have any questions.
Only a pea-sized amount of stool is needed.
The kit will come with a sterile wooden stick which can be used to access the center of the stool. Do your best to keep litter, grass, and urine out of the sample.
Test kits are valid for one year from the purchase date. If your test kit has expired, we can offer you a replacement at a discounted rate.
Send us a message with the 6-character sample ID (printed on the instruction card and sample tubes) and we can help you place a replacement order.
Your test kit includes everything you need to collect and send your sample:
• An instruction card with a 6-character sample ID
• Step-by-step collection instructions
• A collection tube(s) to hold the sample
• A pre-addressed mailer to return the sample
Please send us a message that includes the 6-character sample ID on the tube, and we can send you a replacement.
Your 6-character sample ID is printed on the sample tube, and on the instruction card that came with your test kit.

The microbiome tests read the DNA of the bacteria in your pet's gut to identify which bacteria are present, and in what quantities.
Our scientists use PacBio long-read sequencing of the full-length 16S rRNA gene, which provides a more detailed view than shorter-read sequencing methods that are commonly used in microbiome testing.
Each test looks at a different part of your pet's microbiome:
• The Gut Health Test analyzes a stool sample to measure your pet's gut bacteria and assess microbiome balance.
• The Oral Health Test analyzes an oral sample to measure your pet's mouth bacteria and oral microbiome balance.
Choose the gut test for digestion, stool, or overall gut health questions, and the oral test for breath, plaque, and dental health.
First, check the return tracking information that came with your kit to see whether your sample is still in transit.
Once your sample is delivered to our lab, it may take 1 business day for the status to update in the Pet Portal.

Supplements
No. We strongly discourage opening the Gut Restore capsules. These capsules have a special delayed-release coating that protects the beneficial bacteria from the stomach acid, allowing them to reach the intestines alive. Opening the capsules significantly reduces their effectiveness because most of the bacteria will be destroyed by stomach acid before they reach the intestines where they are needed
Gut Restore can be given with or without food. If your pet is refusing to take the capsule whole, try wrapping it in soft food, hiding it in a treat, or coating it with a small amount of butter or cream cheese. For medium and large dogs, you can try switching to a smaller sized capsule.
We generally recommend pausing Gut Restore and Gut Rebuild while your pet is on antibiotics. All other Animal Biome supplements can be given at the same time while taking antibiotics.
Our products are designed to be gentle, safe, and effective, even for sensitive pets. As with any supplement, we recommend consulting your veterinarian before starting a new product, especially if your pet has a health condition or is taking other medications.
Yes. Gut Restore and S. boulardii + FOS can generally be taken together. This combination is particularly effective to provide advanced support in pets with severe digestive symptoms.
Gut Restore should be given for at least 30 days, and most pets experience substantial improvement within 90 days. Every pet is different, however, and some may benefit from taking Gut Restore intermittently or continuously on an ongoing basis
Please keep in mind that restoring gut health takes time, patience, and consistency. Once a pet’s symptoms have stabilized on Gut Restore, we recommend transitioning to Gut Rebuild to help restore key gut functions, reinforce progress, and support long-term gut health.
Store supplements in a cool, dry place, away from direct sunlight and humidity.
Refrigeration is not required, but can help prevent powdered supplements from clumping in humid climates.
Powdered supplements may clump or harden if exposed to moisture or humidity. To help prevent this, store supplements in a cool, dry place, keep the desiccant packet in the container, and make sure the lid is sealed tightly after each use.
Clumping typically does not affect the supplement’s effectiveness, but can make it more difficult to administer.
If your supplement has hardened, changed appearance, or you are unsure whether it is still okay to use, please contact us with your order number, the product name, and a photo of the supplement. We’ll help you determine the best next step.
We generally recommend starting with a Gut Microbiome Test. Testing helps identify what is going on in your pet’s gut, which can make it easier to choose the most appropriate next step.
Gut Microbiome Tests for cats and dogs include a 15-minute consultation with one of our Microbiome Health Advisors. During the consultation, the advisor can review your pet’s results, provide additional insights, and help create an actionable plan to improve your pet’s health.
FMT stands for fecal microbiota transplant. It is a microbiome support approach that provides a diverse community of beneficial gut microbes from healthy, carefully screened donor cats or dogs.
Gut Restore is an orally administered FMT supplement provided in easy-to-give capsules. It is our most comprehensive microbiome support option, and is typically used for a defined period of time rather than as a long-term daily supplement.
Gut Restore is a fecal microbiota transplant (FMT) supplement designed to restore a healthy, balanced community of dog-specific or cat-specific gut bacteria. It is typically the best choice for pets experiencing significant or ongoing symptoms that suggest a disrupted gut microbiome.
Gut Rebuild is a targeted probiotic supplement designed to restore key gut functions and rebalance the microbiome. It is the best choice for pets with recurring digestive issues or as the next step after a pet has stabilized on Gut Restore.
Gut Maintain is a probiotic and prebiotic supplement designed to nourish beneficial gut bacteria while helping prevent the overgrowth of harmful bacteria. It is the best choice for long-term digestive support in pets prone to diarrhea flare-ups, or those that need ongoing support to maintain a healthy, balanced gut.
You can think of your pet’s gut as a garden: Gut Restore replants the garden, Gut Rebuild improves the soil, and Gut Maintain keeps the garden thriving long-term.
