Why the Chews Stopped Working

Glucosamine supplies building blocks for cartilage. But every step your dog takes also creates "rust" inside the joint, and older dogs can't clear it as fast. You were adding building materials to a house that was still rusting. Mighty-K9 helps protect against the rust.

She Stopped Greeting Me at the Door. Now She's the First One There.

Lucy had gotten so slow she barely got up when I came home, and it broke my heart. After just a few weeks of adding Mighty-K9 to her food, she’s back to waiting for me by the door with her tail wagging like the old days. She’s moving around so much more easily now, it’s like we got our sweet girl back.

He Hadn't Jumped Into My Truck in Two Years. Last Saturday He Did.

Buster used to ride shotgun everywhere with me, but his hips got so stiff he stopped even trying to get into the cab. I started adding Mighty-K9 to his meals hoping it would just make his day-to-day a bit more comfortable. Last weekend, I opened the passenger door and he hopped right up onto the seat like he used to. Having my co-pilot back has been absolutely unbelievable.

Week 2 He Stood Up Faster. Week 6 He Played Fetch.

Maverick was getting so stiff he struggled to even get out of bed in the mornings. After two weeks on Mighty-K9 he was getting up much easier, and by week six, he actually brought me his ball to play fetch for the first time in a year. He still has occasional slow days, but the overall difference in his mobility is incredible. It gave me my boy back. We will never go a single day without it again.

Questions Owners Ask

What is Mighty-K9?

A daily liquid supplement for dogs: organic extra virgin olive oil with ESS60 and a natural bacon flavor. You drizzle it on your dog's food once a day.

How is it different from the joint chews I've already tried?

Most chews supply cartilage building blocks like glucosamine. Mighty-K9 contains none of those. Its job is to help protect joint cells from everyday wear. If your dog already takes a chew, you can keep it.

What is ESS60?

A pure form of carbon-60, a powerful antioxidant, dissolved in olive oil so your dog's body can use it.

How much do I give, and how long does a bottle last?

Each 60 mL bottle holds 30 servings. Bigger dogs need a little more each day, so a bottle lasts them less time: small dogs about [##] days, medium [##], large [##], XL [##]. Use the serving calculator for your dog's exact amount.

How soon will I notice a difference?

Many owners notice easier mornings in 2–3 weeks, with the biggest changes usually by week 8. Every dog is different.

My dog is a picky eater. Will they take it?

Most dogs love the bacon flavor. If yours won't take it, you're covered by the money-back guarantee.

Is it safe with my dog's medications?

If your dog takes any medication, especially anti-inflammatories, steroids or blood thinners, check with your vet before adding any supplement.

Is it only for senior dogs?

It's designed for dogs 7 and older. Many owners of active large breeds start earlier to help keep joints comfortable. For puppies under 6 months, ask your vet first.

Is it safe? Any side effects?

Each serving is a small amount of olive oil (about 16 calories). Dogs with a history of pancreatitis or on a low-fat diet should check with their vet first. Store the bottle in a cool, dark place.

Where is it made, and how is it tested?

Made in Texas in a GMP-certified facility. Every batch is third-party tested for purity and potency.

How does the guarantee work?

Try it for [30/90] days. If you don't see a difference, email support@mighty-k9.com and send the bottle back, even if it's empty, for a full refund of your purchase price. [Return shipping policy.]
