Everything your dog needs.
One chew a day.
Joints, gut, coat, and immunity in one daily chew. 25 active ingredients, dosed to matter. Free from wheat, soy, and corn — nothing artificial.
Bigger dogs take more chews per day, so a jar lasts fewer days.
Your dog does everything for you.
This is one chew for them.
Joints that keep up
The hesitation at the bottom of the stairs is usually the first thing to go. Plus 60 mg of chondroitin — real doses that support cartilage and keep active and older dogs moving like themselves.
A gut that actually works
Good digestion shows up everywhere else — steadier energy, a settled stomach, a better coat. Plus a full digestive-enzyme blend, working where most of the immune system actually lives.
A coat people notice
Less hair on the couch, less scratching, more shine — usually the first change owners point to. Biotin supports skin and coat from the inside, where a good coat actually starts.
Eight vitamins in one chew
The gaps a food bowl quietly leaves, filled in. A full B-complex alongside vitamins A, C, D3, and E — tucked into a soft chew your dog takes like a treat.
A label you can read
Only what works. Free from artificial flavors, colors, and preservatives — a short ingredient list you can actually read, the standard you'd set for yourself.
One and done
No row of bottles to juggle. Chicken and sweet potato is a flavor dogs crave more than beef — they will be begging for KOTO.

Straight answers.
Is this just another joint supplement?
No. Joint support is one part of the formula. KOTO is a full daily foundation — joint and mobility, skin and coat, gut health, and a complete multivitamin base — in one chew rather than a single-purpose product.
How soon will I see a difference?
Every dog is different. Many owners notice more energy and a better coat within a few weeks. Joint and mobility support usually builds over 4 to 8 weeks of daily use. Give KOTO a full cycle to see what it can do.
How do I introduce KOTO to my dog?
Start with half a dose for the first 5 to 7 days, then move to the full amount. This gives the digestive system time to adjust. Most dogs take KOTO straight from your hand. The chicken and sweet potato flavor also makes KOTO a great training reward and a simple way to encourage good behavior.
What if my dog won't eat it?
KOTO is made as a soft, palatable chew most dogs take like a treat. If yours will not, reach out. We stand behind KOTO with our money-back guarantee.
Is KOTO safe for puppies, seniors, and dogs on medication?
KOTO is formulated for adult dogs of all sizes, with dosing tiered by weight. For puppies under 12 months, dogs with existing health conditions, or dogs on prescription medication, check with your veterinarian first — glucosamine and probiotics are generally well-tolerated alongside most medications, but your vet knows your dog best.
How does the dosing work for my dog's size?
Easy. You choose your dog's size at checkout, and each shipment is timed to how fast they finish a jar:
- Small (up to 25 lbs) — every 60 days
- Medium (26–50 lbs) — every 30 days
- Large (51–75 lbs) — every 20 days
- XL (75+ lbs) — every 15 days
One jar, one price. Smaller dogs simply receive KOTO less often.
Can I cancel or postpone?
Yes. There is no lock-in. Pause, postpone, or cancel anytime from your account. Every order is backed by our money-back guarantee.
One chew.
Everything they need.
Everything your dog needs in a day, in one soft chew they look forward to — and the quiet end of the half-used bottles crowding your counter.
