The short answer
Where can I buy Mighty K9?
The safest place to buy Mighty K9 is the brand's secure checkout, which opens from every order button on this site. Orders placed there show up at the order desk, so they can be tracked, changed and refunded.
This website is run by Gomightyk9, an authorized Mighty K9 shop. We are not the manufacturer, and we do not make or bottle the drops. We earn money when you buy through our order links. That is why we tell you exactly where those links go: to the same checkout the brand uses.
When we checked the Mighty K9 store on October 12, 2026, one bottle was $64.99 (sale price), 3 bottles were $269.97 and 6 bottles were $539.94. The sales page says free shipping on orders over $100. Prices can change, so read the total, shipping and tax on the order page before you pay. The full breakdown is on the pricing page.
Marketplaces
Is Mighty K9 sold on Amazon, Chewy or Walmart?
We cannot say whether Mighty K9 is listed on Amazon, Chewy, Walmart or eBay on any given day, and we make no claim either way. Listings on big marketplaces come and go, and anyone with a seller account can post one.
What we can say is narrower. We can only vouch for orders placed through the brand's checkout. The order desk cannot see a marketplace order, so it cannot refund one under the 30-day guarantee. If you buy elsewhere, that seller's own return rules apply, not the brand's.
Saying "only sold here" would be a claim we cannot check every day. Saying "also on Amazon" could send you to a seller we know nothing about. So we stick to what we know: the checkout behind our buttons is the brand's own.
Why it matters
Why does the seller matter more for C60 oil?
With an oil like this, what is in the bottle depends on how it was made, stored and shipped. A 2021 study bought commercial C60 olive oil products and tested them. Their strength varied, and some were off their label strength by more than 18% (Grohn 2021, mice).
The same study found a second problem. C60 oil left in bright light for 4 to 8 days became toxic and killed about 25 to 50% of the mice that got it within 14 days (Grohn 2021, mice). Light is also the main threat to olive oil itself (IOC, Olive oil storage). A bottle that sat in a sunny warehouse or a hot truck may not be the oil you meant to buy.
Pet supplements need no FDA review of quality before sale, and quality control across the market is uneven (Tufts Petfoodology, Supplements). That makes a known supply chain worth more than a small saving. For what the lot and certificate codes on the bottle mean, see batch verify.
Side by side
Official checkout vs a marketplace listing
| Question | Brand checkout (our order buttons) | Marketplace or unknown site |
|---|---|---|
| Who sells it? | The brand's checkout; Gomightyk9 is an authorized shop | Unknown; could be anyone with a seller account |
| Can the order desk see your order? | Yes, with your order ID | No |
| 30-day money-back guarantee | Yes, per the sales page, empty bottles included | Only the seller's own policy |
| Storage before it ships | Not published; ask the order desk | Unknown |
| Price | Shown on the order page before you pay | Varies; may not match |
| Real bottle and label | Comes through the brand's own order system | Cannot be checked before it arrives |
The guarantee is the biggest difference. It is a purchase policy, not a health promise, but it only works when the order desk can find your order.
Checklist
How do I spot a fake Mighty K9 listing?
Check these before you buy anywhere, and again when the box arrives.
On the listing
- The product is described as liquid drops in a 2 fl oz (60 mL) bottle, not chews or capsules.
- The photos show amber glass, a black dropper bulb and a cream label with a spaniel.
- The ingredient line reads: extra virgin olive oil, ESS60 and bacon flavor. Nothing else.
- The serving is 2 mL, with 30 servings per bottle.
- No claims that it cures, heals or treats arthritis. The real label makes none.
On the bottle
- The front reads "NET WT. 2 FL OZ (60ML)" and "Contains 100% ESS60".
- The Guaranteed Analysis lists ESS60 at 1.6 mg and 16.2 kcal per 2 mL.
- The cap and dropper are undamaged and the oil looks clear, not cloudy or rancid.
- The box did not arrive hot to the touch or soaked in oil.
- A lot and best-by may be printed on the base; write them down.
Price is a clue too. A total far below the $64.99 the store showed for one bottle on October 12, 2026, from a seller with no history, is a reason to stop. So is a burst of five-star reviews in a few days; the FTC notes you cannot reliably spot fakes just by reading them (FTC, Evaluating reviews). Compare every line with the real Guaranteed Analysis.

Order nowThe real thing
What does a real Mighty K9 order look like?
A real order comes with a confirmation email that holds your order ID and, once it ships, a tracking link. Keep that email until well after the 30-day window. It is the one thing that ties the bottle in your hand to the guarantee. Shipping steps are on the shipping page.
Refunds
Can I get a Mighty K9 refund if I bought it somewhere else?
Refunds only work with an order ID from the brand's checkout. The order desk uses that ID to find your order, confirm the date and send the money back to the card you used. Without it, there is nothing for the desk to look up.
Find the order email
Search your inbox for the confirmation. The order ID is near the top.
Call within 30 days
Phone +1 (302) 200-3480 and give the order ID. Ask for a return authorization (RMA) number before you mail anything.

FAQ
Where to buy Mighty K9: FAQ
Is Mighty K9 sold in stores like PetSmart or Petco?
We have no information that Mighty K9 is sold in pet stores, and we make no claim either way. The checkout we link to is the brand's own online order page. If you find it in a store, check the bottle against the label details and ask about returns before you buy.
Is Mighty K9 on Amazon?
We do not claim it is or is not on Amazon. Listings there can be posted by any seller, and we cannot check them. The order desk cannot see or refund a marketplace order, so the 30-day guarantee applies only to orders from the brand's checkout.
Is gomightyk9.com the official Mighty K9 website?
Gomightyk9 is an authorized Mighty K9 shop, not the manufacturer. Our order buttons open the brand's secure checkout, so orders go to the same order desk that handles tracking and refunds. We earn money when you buy through those links.
How can I tell if my Mighty K9 bottle is fake?
Compare it with the real label: a 2 fl oz (60 mL) amber glass dropper bottle, cream label, three ingredients, 1.6 mg ESS60 and 16.2 kcal per 2 mL. A damaged cap, cloudy oil or a different ingredient line are warning signs. Call the order desk before you use it.
Why is Mighty K9 cheaper on some websites?
A lower price can mean old stock, poor storage, a fake or a site with no refund path. A 2021 study found some commercial C60 oils were off label strength by more than 18%. On October 12, 2026 the brand's store showed one bottle at $64.99 and 6 bottles at $539.94; its checkout shows the real total before you pay.
Can I return Mighty K9 bought on eBay?
Not through the brand's guarantee. The order desk needs an order ID from the brand's checkout to process a refund. For an eBay purchase, use eBay's own return process and contact that seller directly.
Does Mighty K9 ship to my door from the official site?
Yes. Orders from the brand's checkout ship from the U.S. unless the sales page says otherwise, with tracking in the order email. Delivery times are not published, so ask the order desk at +1 (302) 200-3480 if timing matters.
