Official sellers
Where can I buy Mighty K9?
There are two places we can confirm sell Mighty K9: this site and the brand's own store at mighty-k9.com. Both send you to an order page with the same three pack sizes.
This site is run by Mymightyk9, the U.S. stocking partner for Mighty K9. We are not the manufacturer. We earn money when you buy through our order links, and we say so on every page.
Orders placed through this site are handled by the order desk at +1 (302) 200-3480. Orders placed directly on mighty-k9.com follow the brand store's own policies and support line, (713) 432-9245 (Mighty-K9, refund policy). Keep track of which one you used. It decides who handles your refund.
Side by side

Marketplaces
Is Mighty K9 sold on Amazon, Chewy or Walmart?
We could not confirm any Mighty K9 listing on Amazon, Chewy, Walmart or in pet stores. That does not prove none exists, but we cannot vouch for one.
Marketplaces let many sellers list under the same product name. A listing can look official and still ship from a third party you know nothing about. That matters more for an oil with an active ingredient than for a bag of kibble.
If you do find Mighty K9 on a marketplace, do three things before you pay:
- Check who the seller is. Look for a business name and address, not just a store nickname.
- Compare the listing photos with the label facts below. Any change in size, ingredients or wording is a warning.
- Read the seller's own return policy. The 30-day guarantee on this site does not cover bottles bought elsewhere.
Why it matters
Are copycat C60 oils for dogs a risk?
Yes. C60 oils are hard to judge by eye, and a 2021 study found that commercial C60 oils varied in concentration and purity (Grohn et al., 2021). The same study found that C60 in olive oil breaks down in light, and the light-exposed oil made mice ill.
That gives two real risks with an unknown seller. First, the bottle may hold less C60 than claimed, or a different one. Second, a bottle stored in a hot, bright warehouse may have broken down before it reaches you.
Whatever the source, store Mighty K9 closed, in a cool, dark cupboard, as the label says. Do not leave it on a sunny windowsill or counter.
ESS60 itself is a trademark of SES Research Inc. for its C60 ingredient (USPTO via Justia, ESS60). A bottle that just says "C60" is not the same claim as one that names ESS60. The ESS60 ingredient page explains the difference.
Spot a real bottle
How can I tell if my Mighty K9 bottle is real?
A real bottle matches the label facts exactly. Hold your bottle next to this list and check each line.
Size and look
An amber 2 fl oz (60 mL) dropper bottle with a cream label and a spaniel's face. The label reads MIGHTY-K9 Canine Supplements.
Front claim
Organic Extra Virgin Olive Oil, Contains 100% ESS60, Bacon Flavor, Net Wt. 2 fl oz (60 mL). Different wording, or anything that is not liquid drops, is a different product.
Ingredients
Exactly three: Extra Virgin Olive Oil, ESS60 and Bacon Flavor. Extra fillers or a longer list means a different product.
Guaranteed Analysis
ESS60 1.6 mg per 2 mL serving, 30 servings per container, and 16.2 kcal per serving.
Warning text
For canine use only. Keep out of reach of children and animals. In case of accidental overdose, contact a health professional immediately.
Seal and smell
An intact seal on arrival and a light oil that smells of bacon. A sharp or rancid smell is a reason to call.

Red flags
What are signs of a fake Mighty K9 seller?
The clearest sign is a claim the real product never makes. Mighty K9 is sold as a supplement for joint comfort, not as a medicine.
- Promises that it cures arthritis, ends pain or replaces your vet. The real sales page does not say that, and a product sold to treat disease would legally be a drug (FDA, Unapproved Animal Drugs).
- A price far below the brand store, or a crossed-out "was" price with a big percent off.
- Star ratings and hundreds of glowing reviews with no way to check them. We publish no rating until reviews are matched to real orders.
- No phone number, no address and no return policy.
- A capsule, chew or powder sold under the Mighty K9 name.
If something feels off, stop and call the order desk at +1 (302) 200-3480 before paying. It takes a few minutes and can save you a bad bottle.

FAQ
Where to buy Mighty K9: common questions
Can I buy Mighty K9 on Amazon?
We could not confirm a Mighty K9 listing on Amazon. If you see one, check that the seller is a real business with an address, that the label matches the 2 fl oz bottle with ESS60 and three ingredients, and that a return policy exists. Our guarantee does not cover Amazon orders.
Is Mighty K9 sold at Chewy or Petco?
We could not confirm Mighty K9 at Chewy, Petco or other pet stores. The two sellers we can confirm are this site, run by the U.S. stocking partner, and the brand store at mighty-k9.com. Both list the same 1, 3 and 6 bottle packs.
Is Mighty K9 sold at Walmart?
We could not confirm a Walmart listing for Mighty K9, online or in stores. Marketplace listings can come from third-party sellers, so check the seller's name, address and return policy, and compare the photos with the real label before you buy.
Is mymightyk9.com the official Mighty K9 website?
Mymightyk9.com is run by the U.S. stocking partner for Mighty K9, not by the manufacturer. We sell through official order links and earn money when you buy. The brand's own store is mighty-k9.com, which has its own support line and refund rules.
How do I know my Mighty K9 is not fake?
Check that it is an amber 2 fl oz dropper bottle listing exactly three ingredients: extra virgin olive oil, ESS60 and bacon flavor, with 1.6 mg of ESS60 per 2 mL. A different size, extra ingredients or any form other than liquid drops means it is not the real product.
Is it safe to buy C60 oil for dogs from any seller?
Not always. A 2021 study found commercial C60 oils varied in concentration and purity, and C60 in olive oil broke down in light into products that made mice ill. Buy from a seller you can identify, and keep the bottle in a cool, dark place.
Who do I call about a Mighty K9 order?
For orders placed through this site, call the order desk at +1 (302) 200-3480 with your order ID. For orders placed on mighty-k9.com, contact the brand store at [email protected] or (713) 432-9245, Monday to Friday, 9 AM to 5 PM CST.
