Mighty K9 FAQ: Answers About ESS60 Drops for Dogs

Mighty K9 is a bacon-flavored liquid oil for dogs, sold in a 2 fl oz (60 mL) amber glass dropper bottle. Each 2 mL serving is extra virgin olive oil carrying 1.6 mg of ESS60, a trademarked C60 ingredient. The sales page positions it for everyday joint comfort in dogs.

Mighty K9 is a liquid. It comes as an oil in a glass bottle with a dropper, not as a soft chew, tablet or capsule. You measure 2 mL and stir it into food. That makes it easy to hide in a meal but harder to give on a walk.

Orders go through the brand's checkout and an order desk run by BuyGoods at +1 (302) 200-3480. Getmightyk9 is a U.S. retail partner for the brand, not the manufacturer, and earns money when you order through its links. The label images we have do not name a manufacturer.

No. Mighty K9 is labeled and sold for dogs only. The label carries a calorie statement in dog-food format and an AAFCO note, both written for animal feeding. Anyone curious about C60 for themselves should ask their own doctor rather than borrow the dog's bottle.

Neither word fits perfectly. U.S. law has no dietary supplement category for animals: a dog product is legally either an animal food or a drug (AAFCO, n.d. (food vs drug)). Mighty K9 is sold like an animal food with a feeding analysis. It is not an approved veterinary drug.

The sales page says it supports joint comfort, eases everyday stiffness, supports cartilage and connective tissue and helps with cellular aging. Those are the seller's words. No study has tested ESS60 or Mighty K9 in dogs with joint problems, so treat the claims as unproven.

No safety study of Mighty K9 or ESS60 in dogs has been published. Short rat studies of C60 in olive oil reported no harm at tested doses, but rodents are not dogs (Burres et al., 2024). The clearest known risk is the fat: each serving is pure oil, which matters for dogs prone to pancreatitis.

Ask your vet first. Mighty K9 is 100% fat, and high-fat foods are a known risk factor for pancreatitis in dogs (Animal Medical Center, n.d.). Dogs that have had it are usually kept on a low-fat diet (Steiner, Merck Veterinary Manual, 2025). Watch for vomiting, belly pain, poor appetite or weakness.

No known interaction between olive oil, C60 and NSAIDs has been reported, but none has been studied either. Tell your vet before adding it. Never stop or replace a prescribed pain reliever with drops, and never give a dog human pain relievers such as ibuprofen (FDA, n.d. (pain relievers)).

The label gives no guidance on age, pregnancy or nursing. Growing puppies and pregnant dogs have special diets, and C60 has not been studied in either. Ask your vet before giving it. Most puppies have no reason to need a joint product anyway.

No side-effect data for Mighty K9 exist. With any added oil, the common problems are loose stool, an upset stomach and slow weight gain. Stop it and call your vet if you see vomiting, diarrhea that lasts more than a day, or a dog that stops eating. Full details are on our side effects page.

No. The FDA does not approve dog supplements before sale, and Mighty K9 is not an approved animal drug. Products that claim to treat or prevent disease can be treated by the FDA as unapproved animal drugs (FDA, n.d. (labeling and claims)). An approved joint drug, such as Librela, is a prescription vet injection (FDA, 2023 (Librela)).

Yes, especially if your dog limps, takes medicine, is overweight, or has had pancreatitis. Bring the bottle or a photo of the label panel. Ask your vet whether 16.2 extra kcal a day fits the dog's calorie plan and whether fish-oil omega-3s would be a better first step.

Yes. The sales page shows a 30-day money-back guarantee that includes empty bottles. Return shipping is not refunded, so you pay to mail bottles back. Confirm the current terms on the order page before you buy, since policies can change.

Call the order desk at +1 (302) 200-3480 with your order ID, and email [email protected] for a return number. Mail the bottles, even empty ones, with your full name, email and order ID to the returns address. Use a tracked service. Full steps are on the refund policy page.

The sales page says refunds take 3-5 business days after the returned bottles are credited, then 5-10 days for your card issuer to post it. Timing runs from when the returned bottles are logged in, not from the day you post them. Keep your tracking number until the money shows up. If it has not posted after that window, call the order desk with the order ID and the tracking number.

Yes. The sales page says the guarantee includes empty bottles, so you can try the product and still return the bottle. Send every bottle from the order back together, with your name, email and order ID inside the package, and keep the tracking number.

Phone the BuyGoods order desk on +1 (302) 200-3480, or write to [email protected]. Only that desk can see orders, tracking and charges. The website inbox at [email protected] handles questions about our pages, privacy and press, and it cannot look up orders.

A dog that drinks a whole bottle has eaten a lot of fat at once. Call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435, open 24 hours a day; a fee may apply (ASPCA, n.d.). Watch for vomiting, diarrhea and belly pain.
