The full list of available services and their corresponding prices is displayed at checkout before the order is placed. Not all services are available in all locations.

If your international order is being held by customs, please contact your local customs office or carrier. They may need additional information from you, such as payment of duties, taxes, VAT, or other import fees, before the package can be released. We encourage you respond promptly to any requests from customs or the carrier.

Customs processing times vary by country and are unfortunately not within our control. If your shipment’s tracking information has not updated for the past 7 days, please contact us with your order number so we can help review the shipment status.

International orders may be subject to customs fees, duties, VAT, taxes, or other import charges. These fees are set by your country's customs office, and are not included in our product or shipping prices unless clearly stated at checkout.

Customers are responsible for any applicable import fees required by their country. We recommend checking with your local customs office before ordering if you have questions about potential charges.

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 Microbiome Test analyzes a stool sample to measure your pet's gut bacteria and assess microbiome balance.
• The Oral Microbiome 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.

We recommend discontinuing bacterial probiotics at least 24 hours before collecting the stool sample. Your pet can continue taking supplements with yeast based probiotics (such as Saccharomyces boulardii) during sample collection.The Gut Microbiome Test looks at bacteria only, and S. boulardii is a yeast, so it will not impact the results of the test.

It is not necessary to pause antibiotics to collect a sample for testing. However, if your pet is on a short-term antibiotic course, you may wish to wait until the course is complete before collecting the sample. This timing can offer a more accurate reflection of any impact the antibiotics may have had on your pet's microbiome.

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

You may collect an Oral Microbiome test sample as soon as 1 week after the dental cleaning.

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 with a replacement order.

No, you do not need to refrigerate or freeze your sample before mailing it.

Gut Microbiome Test sample tubes contain a specially formulated preserving liquid that helps keep the bacteria stable during transit, including during shipping delays and exposure to hot or cold temperatures.

Oral Microbiome Test samples also remain stable during normal shipping conditions and do not require refrigeration.

A delay in transit will not compromise the quality or accuracy of your test results.

The Gut Microbiome Test includes instructions and everything you need to prepare your pet's sample.

1. Collect a fresh stool sample. For dogs, use stool passed within the previous 4 hours. For cats, use stool passed within the previous 4 hours or collected first thing in the morning.
2. Use the collection tools provided in your kit to take a pea-sized sample from the center of the stool.
3. Place the sample into the collection tube and seal it securely.
4. Follow the instructions included with your kit to return the sample to our laboratory.

For U.S. returns: Place the sealed collection tube in the provided bag and return mailer.

• Kits purchased on or before May 31, 2026 are returned via FedEx.
• Kits purchased June 1, 2026 or later are returned via USPS.

For international returns: Follow the return instructions included with your International Gut Microbiome Test. You may use the carrier of your choice.

While your sample is on its way to our lab, please use the return shipping tracking to monitor its progress.
Once we receive your sample and begin processing it, you will receive an email notification to confirm, and the status will update in the Pet Portal at app.animalbiome.com.
If your return tracking shows the sample was delivered but your Pet Portal status has not updated within 1 business day, please contact us with your pet’s 6-character sample ID so we can check on it for you.

Sample should be collected and placed in the vials within 4 hours of elimination for dogs, or first thing in the morning for cats

Send us a message that includes the 6-character sample ID on the tube, and we can send you a set of replacement vials.

Your 6-character sample ID is printed on the sample tube, and on the instruction card that came with your test kit.

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.

Supplements need to be stored 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.

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.

The following supplements come in both 30g & 60g jars
S. boulardii + FOS contains a 1cc scoop (1/5 tsp)

• 30g jar contains 53 scoops
• 60g jar contains 107 scoops

Daily Digest contains a 1cc scoop (1/5 tsp)

• 30g jar contains 43 scoops
• 60g jar contains 86 scoops

The following supplements come in 60g jars

• Mushroom Biome Blend contains a 1cc scoop (1/5 tsp) and contains approximately 105 scoops
• Oral Cleanse contains a .5cc scoop (1/10 tsp) and contains approximately 180 scoops
• Gut Defend contains a 2cc scoop (2/5 tsp) and contains approximately 70 scoops

The following supplement comes in a 90g jar

• Fiber Biome Blend contains a 2cc scoop (2/5 tsp) and contains approximately 90 scoops

Though they are rare, the most common side effects are diarrhea, vomiting, and lack of appetite. Following the slow introduction protocol helps mitigate these side effects for sensitive pets.

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.

Most medications and supplements can be continued while your pet is taking Gut Restore. The main exception is bacterial probiotics, such as those containing Lactobacillus, Enterococcus, or Bifidobacterium strains. When possible, we recommend discontinuing bacterial probiotics because they may compete with the cat- or dog-specific bacteria in Gut Restore and reduce its effectiveness.

Bacterial probiotics are also commonly found in pet foods, treats, dental chews, and supplements, so avoiding them completely may not always be practical. If they cannot be avoided, we recommend limiting bacterial probiotics to 250 million CFUs per 10 pounds of body weight while using Gut Restore.

The yeast-based probiotic S. boulardii can be used with Gut Restore because it does not compete with the beneficial bacteria in the supplement.

If your veterinarian has prescribed a probiotic or other medication for your pet, check with them before making any changes to your pet’s treatment plan.

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.

When possible, we recommend giving one capsule in the morning and one in the evening. Delivering the Gut Restore material more gradually may be more effective and provide faster results. Day-to-day consistency is more important than if the daily recommended amount is split up.

Gut Restore can be given with or without food.

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-administer 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.

Yes, if your dog has trouble taking capsules whole, you can open the capsule and mix the powder with food or a treat.

Yes, Skin Rescue can be used long-term.

In rare cases, this product can cause cause worsening of diarrhea or more commonly, constipation. Discontinue use if severe side effects occur.

Yes. The job of Daily Digest is to help break down your pet’s food. To maximize the benefits of the enzymes in Daily Digest, the powder must be added to each meal.

Oral Cleanse is not intended for use in pets with hyperthyroidism. Pets taking other iodine-rich supplements or medications should use Oral Cleanse with caution and with veterinary supervision.

This supplement can be given with any other medications and/or supplements with the exception of iodine-rich supplements or medications (for example, marine-derived ingredients like kelp). While we have seen many pets benefit from this supplement, we always recommend checking with your veterinarian before changing their regimen.

While this supplement is intended specifically for cats and dogs with an overgrowth of E. coli bacteria, in rare cases, it can cause symptoms to worsen. If your pet’s symptoms worsen after beginning this supplement, stop giving the supplement until their condition stabilizes.

We have found that, for the large majority of pets, intermittent use of Gut Defend for two weeks at a time is just as effective as daily use for reducing pathogens.

Most pets do not have an issue with longer-term use of clay-based products. However, in some pets, prolonged use of clays may interfere with the absorption of certain vitamins, minerals, or medications.

If you plan to use Gut Defend continuously for an extended period, we recommend consulting with your veterinarian.
