Where is the Mighty K9 lot number?
On the label panel image, there is no lot code. We checked the panel, and it shows the serving, the Guaranteed Analysis and the ingredients. It does not show a lot number.
That does not mean your bottle has none. A bottle may carry a printed or stamped code somewhere on the label, the cap or the glass. The only way to know is to hold your own bottle under a good light and look. Turn it slowly, and check the base and the neck as well as the front.
If you find a code, photograph it right away. Keep the photo with your order email. The photo is your record if you ever need to ask a question.
What is the lot number the seller gives for Mighty K9?
The seller reference is lot MK-26/TH-4089. It comes with a CoA reference, MK-4089-26-TH. We show both on our pages because the order desk can use them to find a batch record.
Be careful with the word reference. These codes are what the seller uses to identify a batch. They are not a lab report. They do not prove what is in your bottle, and they do not prove the amount of ESS60.
| Code | Value | What it is | What it is not |
|---|---|---|---|
| Lot reference | MK-26/TH-4089 | A seller batch reference | Proof of contents |
| CoA reference | MK-4089-26-TH | A file number you can ask about | A published lab result |
| Third-party lab report | Not published | The real proof of the ESS60 amount | Something we can show |
Is the Mighty K9 CoA a lab report?
No. A real certificate of analysis is a dated document from a lab. It names what was tested, the method, and the results. We have not seen such a document for Mighty K9.
The page for testing and quality says the same thing. The product page claims a GMP-certified facility, but it names no certifier. There is also no NASC Quality Seal. So the code MK-4089-26-TH is a file number to ask about, and nothing more.
This matters because commercial C60 oils have been tested at 0.57 to 1.4 mg per mL in one published study. The label here works out to 0.8 mg per mL. Without an outside test, nobody outside the company can confirm the figure. Ask the maker for proof if that matters to you.
Why does the Mighty K9 lot number matter?
A lot number ties a bottle to one batch. If a problem is found in a batch, the number lets the company and the buyer work out who is affected. It is the thread that connects a bottle to its records.
It also helps you. If your dog has a reaction, or the oil smells wrong, the lot number is the first thing a company or a regulator asks for. Without it, a complaint is harder to follow up.
Think of it like the receipt for a bottle. You hope you never need it. If you do, it saves a lot of time.

How do you match your Mighty K9 bottle to your order?
Photograph the bottle
Take clear photos of the front, the cap, the base and any printed code. Do it before the first serving.
Find your order ID
It is in the confirmation email. Keep that email until the bottle is finished.
Call the order desk
The number is +1 (302) 200-3480. Quote your order ID and the code you see.
Write down the answer
Note the name of the person you spoke to, the date and what they said.
The website inbox cannot see orders. Use the phone line for anything about a batch, a refund or tracking. That keeps your question with the people who can open the order record.
When should you report a problem with the lot number?
Report a problem when your dog has a bad reaction, when the oil smells sharp, sour or stale, or when the seal is broken on arrival. Stop using the bottle first. Call your vet if your dog is unwell.
The FDA takes reports about pet products, and it asks for the lot number and the best-by date when you file. Keep the bottle, the box and the order email until the matter is settled. A short written note of what happened and when helps a lot.
You can also tell the order desk. Say which bottle it was, what you saw, and ask what the next step is.
What else should you check besides the Mighty K9 lot number?
Check the seal, the glass and the oil. The bottle should be amber glass with the cap seal whole. The oil should look like clear golden-green olive oil and smell mild. The front of the label reads Organic Extra Virgin Olive Oil, Contains 100% ESS60, Bacon Flavor, Net Wt. 2 fl oz (60 mL).
Cold oil can turn a little cloudy and clear up again at room temperature. That alone is normal. A sharp, sour or paint-like smell is not normal. Do not use oil that smells like that.
If you ordered a 3-bottle or 6-bottle pack, check every bottle when the box arrives. Do not stop at the first one.
How do you track a Mighty K9 lot number across a multi-bottle pack?
Whether every bottle in a 3-bottle or 6-bottle pack shares one lot is not published to us. So do not assume. Treat each bottle on its own.
Make a simple log with one line per bottle: the bottle number, the date it arrived, the date you opened it and any printed code. A phone note works well. Photograph each bottle next to the box.
This takes five minutes when the parcel arrives. It saves a long hunt months later, when you are on the phone and only have a half-empty bottle in your hand.
Do you need the Mighty K9 lot number for a refund?
The sales page does not say that a lot number is needed. The return steps ask for your full name, your email and your order ID, and they say to call the order desk first.
Still, a photo of the bottle and its code costs nothing, and it helps if the desk asks which batch you had. The money-back window is 30 days and it counts empty bottles. Buyers pay return shipping, so choose a tracked service.
Frequently asked questions
Where is the Mighty K9 lot number?
It is not on the label panel image. Look at your own bottle: the label, the cap and the base. If you cannot find one, call the order desk.
What is lot MK-26/TH-4089?
It is the seller's batch reference for Mighty K9. It is a seller reference, not lab proof.
Is MK-4089-26-TH a lab certificate?
No. It is a CoA reference, a file number you can ask about. A third-party lab report is not published.
Who can match my bottle to my order?
The order desk at +1 (302) 200-3480. Have your order ID and a photo of the bottle ready.
Why does the FDA ask for the lot number?
The lot number links a product to one batch, so a report can be followed up. The FDA asks for it, along with the best-by date, when you report a pet product problem.
Does the lot number prove the oil is safe?
No. It only identifies a batch. It does not prove the contents or the amount of ESS60.
Our view
Our view: a lot number is useful, but only the real kind. We show the seller's reference because you may be asked for it, and we label it clearly as a reference, not proof.
The best habit is simple. Photograph every bottle on the day it arrives, keep the order email, and know the order desk number. If the maker ever publishes a third-party lab report, that would tell you far more than any code. Treat the Mighty K9 lot number as a record to keep, not a promise.

Mighty K9 is not FDA approved, and no dog supplement is. It is not intended to diagnose, treat, cure or prevent any disease. Talk to your vet about any health question. Limping, pain or stiffness that does not ease needs a vet exam, not just a supplement. Ask your vet first if your dog is under 6 months, has had pancreatitis or needs a low-fat diet, is pregnant or nursing, takes any medicine, or is being treated for a condition.
