Mighty K9 Batch Verify: Check Your Bottle, Match Your Order, Report a Problem
The seller lists lot MK-26/MY-8762 and CoA reference MK-8762-26-MY. These are reference codes, not lab proof. To check your bottle, look at the seal, the lot and best-by on the base if printed, and the oil's color and smell. Match your order by calling +1 (302) 200-3480. Keep the packaging if anything seems wrong.

The codes
What do the Mighty K9 lot and CoA codes mean?
They are reference codes the seller uses to track stock. They are not a lab result, and no certificate of analysis has been published behind them.
A real certificate of analysis names a lab, a test date and actual numbers. A reference code only lets the seller look up a batch. Treat both codes as a starting point for questions, not as proof.

Four checks
How do I check my Mighty K9 bottle when it arrives?
Seal, codes, look and smell, then the order match. Do it before the first serving.
- 01
Look at the box and seal
The cap seal should be whole. A torn or missing seal means do not use it; photograph it first.
- 02
Find the codes
Check the base and label for a lot number and best-by date, if printed. Write them down.
- 03
Look and smell
Open it in good light for a moment. Expect clear oil and a mild olive and bacon smell, nothing sour.
- 04
Match the order
Call the order desk with your order ID. Ask them to confirm the lot that shipped to you.
What to look for
How can I tell if my Mighty K9 bottle is good or bad?
A good bottle is sealed, clean and smells mild. Anything sour, cloudy or leaking is a reason to stop and call.
| Check | Normal | Problem sign | What to do |
|---|---|---|---|
| Bottle | Amber glass, 2 fl oz (60 mL), cream label with a spaniel face | Clear bottle, different label, misspellings | Do not use; call the order desk |
| Seal | Intact cap seal | Broken, missing or loose seal | Photograph it; do not use |
| Codes | Lot and best-by on the base, when printed | Scratched off or past the date | Note it and ask the seller |
| Color | Clear oil, no floating bits | Cloudy, layered or with sediment | Stop and call |
| Smell | Mild olive oil and bacon | Sour, sharp, like paint or old crayons | Likely rancid; stop and call |
| Label text | Three ingredients; 1.6 mg ESS60; 16.2 kcal per 2 mL | Different ingredients or amounts | Keep it; report it |
The amber glass protects the oil. A 2021 mouse study found C60 in olive oil breaks down in light, and the light-exposed oil made mice sick (Grohn et al., 2021). A bottle that arrived in a sunny, open box deserves a closer smell.

How do I report a problem with Mighty K9 to the FDA?
Use the FDA Safety Reporting Portal at safetyreporting.fda.gov. It takes pet food and animal supplement complaints online (FDA, Report a Pet Food Complaint).
The FDA also accepts reports on Form FDA 1932a, emailed to [email protected]. Questions go to 1-888-FDA-VETS (FDA, Report Animal Drug Side Effects). Include the product name, lot, best-by date, where you bought it, your dog's details and what happened.
Tell the seller too, at +1 (302) 200-3480. A report to both helps spot a bad batch faster.
Call your vet first. For a suspected poisoning, ASPCA Animal Poison Control is at (888) 426-4435, 24/7; a fee may apply (ASPCA Animal Poison Control). Vomiting, diarrhea, belly pain or refusing food after a fatty food can also point to pancreatitis (Merck Vet Manual, Pancreatitis (owner)).
Copies
Could my Mighty K9 be a fake?
The safest way to avoid copies is to buy from the brand store or through this site's order links. We are the U.S. stocking partner, not the maker, and we earn money when you buy through our links.
Third-party marketplace listings are harder to trace. If a bottle from anywhere fails the checks above, keep it, call the seller and file a report. See where to buy for the official channels.
Quick rule
What if my Mighty K9 smells rancid?
Stop giving it. Cap the bottle, keep it, and call +1 (302) 200-3480 with your order ID. A sour, sharp or paint-like smell means the oil has likely oxidized.
Your dog has already had some? Watch for vomiting or loose stools over the next day, and call your vet if they appear.
FAQ
Mighty K9 batch and lot FAQ
Where is the lot number on a Mighty K9 bottle?
Look on the base of the bottle and around the label edge. Lot and best-by details are printed there when the batch has them. If you cannot find any, call the order desk with your order ID and ask which lot shipped to you.
Is the Mighty K9 CoA code a lab test?
No. The seller's CoA reference, MK-8762-26-MY, is a code for looking up paperwork, not a lab result. No certificate of analysis has been published. Ask the order desk to email the full report for your lot, with the lab's name, test date and results.
How do I know if my Mighty K9 has gone bad?
Smell it. Fresh oil smells mild, of olive oil and bacon. A sour, sharp or paint-like smell suggests rancid oil, and cloudiness or sediment is also a warning. Stop using it, keep the bottle, and call the order desk with your order ID.
Can I verify Mighty K9 online with the lot number?
There is no public lookup tool for Mighty K9 lot codes. Verification is done by phone: the order desk checks your order ID and the lot that shipped. For orders from the brand's own store, contact that store's support line instead.
How do I report a bad batch of Mighty K9?
Report it to the FDA through the Safety Reporting Portal, or on Form FDA 1932a by email. Keep the bottle, the box and the lot number. Tell the seller as well, so other bottles from the same batch can be checked.
What if my Mighty K9 seal was broken on arrival?
Do not use it. Photograph the seal, the bottle and the box, then call the order desk with your order ID. Keep everything until they reply. A broken seal is a packaging problem the seller should fix, separate from the money-back guarantee.
