"She met me at the door again. I ugly cried."

I almost quit after week 1. Nothing yet. My husband said give it the full month. Week 3 she met me at the door... at 11 years old!! I called him sobbing in the hallway. We got our girl back.

"$120 on Amazon Wasted. This actually works."

I tried 3 different "brain supplements" from Amazon. $120 down the drain. Nothing. Then I read about clinical dosing and realized I'd been giving her expensive rice powder lol. Decade Dog was different by 6 weeks for us

"He's responding to his name again."

Gave him chews for a year. A whole YEAR. Vet said his engagement was getting worse and we were looking into prescriptions and pills. Switched to these drops and about a month later he's responding to his name better than he has in so long! Wish we found this sooner.

What to Expect
Using Decade Dog™ Daily

WEEKS 1 TO 2

Adjustment Period

MCT oil starts delivering "brain fuel" (ketones). Think of it like switching your dog's brain from regular gas to high-octane.

What you might notice:

  • Brighter, more alert eyes. They're "tracking" you around the room
  • Slightly faster response times when you call their name
  • Less morning fogginess

If you don't see anything yet, that's normal. Keep going. More than likely its a bit too early. Consistency in dosage is KEY here.

Adjustment Period
WEEKS 2 TO 4

The Proof Window

This is when most owners text us saying "Holy ****, it's actually working"

What you'll notice:

  • They greet you at the door again (not just lying on the couch)
  • Faster response to commands (first time you call, not the fourth)
  • More engagement during walks (sniffing, exploring, excitement!)
  • Better eye contact (they're PRESENT, not staring through you)

This needs to be something you give your dog every day to get results in this period. Build the habit, you got this!

The Proof Window
WEEK 6

The Checkpoint!

By Week 6, you'll stop wondering 'Is this working?' You'll KNOW.

If you see...

  • Brighter, more alert eyes

  • Faster response when you call their name
  • More engagement (tail wagging, following you around)

KEEP GOING. You're on track! Stay consistent with your daily doses.

The Checkpoint!
WEEKS 8+

Long-Term Restoration

Lions Mane has been growing new brain cells to replace the ones aging destroyed.

What you'll notice:

  • They remember their routine (waiting by the food bowl at 5pm sharp)
  • Nighttime pacing stops (or dramatically reduces)
  • They're calm and CLEAR (not anxious or confused)
  • Spatial navigation improves (less staring at the door confused about how to get outside)

Every day of dosage builds on the last. KEEP GOING. They're not just better. They're rebuilding long-term.

Long-Term Restoration

They Thought Their Dog Was Just Getting Older…

See what 30-60 days of consistency can do for your best friend's longevity.

"No more 3am wake ups."

Murphy is the sweetest boy ever. But the sundowning was killing us!! Every night around 2-3am he'd start pacing and crying. Vet said it was him just starting to get old and a bit anxious. They gave us some light sedatives but we hated drugging him. Saw an ad for Decade Dog and within a month... he sleeps better now. Not a miracle solution but we have been giving it to him for a month. We sleep and aren’t using perscriptions! Can’t believe it honestly

"Duke is back to being Duke."

For the last year he'd just lay there staring at the wall. Wouldn't even look up when we came home. Started Decade Dog in October and by Thanksgiving he was following me around the kitchen again, getting in the way like he used to lol. My daughter said "grandpa dog is happy." He really is

"Getting our great danes past a decade!”

Zeus and Apollo are 6 and 8 year old great dane. Everyone tells us big dogs don't last long and to "enjoy the time we have." Screw that crap. Both are sharp and healthy right now and we're keeping it that way. Been on Decade Dog for 3 months to help keep their brains rocking while their hip and joints start to hurt more as they age. They go through bottles fast but if it gives us even one more good year and out of the vet with these two its worth every penny

"She remembers her tricks again."

Pepper is a 11 yr old Corgi and the smartest dog I've ever had. Watching her forget commands she knew for 8 years was devastating. Sit, stay, come... gone. 5 weeks on Decade Dog and she's responding to hand signals again. Not 100% but way better. We'll take it

"She is back!!!”

Last summer Rosie just felt tired. Like she was here but not here. Hard to explain but if you know you know. We started on Decade Dog’s new formula as soon as it came out and in month 2, she is more calm and tail is wagging! She looks AT me again not through me. Worth every penny

"Noticed changes around week 3"

She is a 11 year old beagle and was getting pretty foggy. Wouldn't come when called, seemed confused about where things were in the house. Started this and honestly didn't notice anything for the first few weeks. Around week 3 my husband said she seemed better and I started noticing it too. Daisy is not back to normal but definitely improved!

Memory Focus
It's Not Just Aging. Their Brain is Exhausted.

Why Older Dogs With Chronic Pain Are Suffering

Mental Exhaustion

Mental Exhaustion

Their brain uses ALL its energy managing pain, with nothing left for you.

Daily Withdrawal

Daily Withdrawal

Like humans with chronic pain, they conserve energy and stop initiating interaction.

Sleep Disruption

Sleep Disruption

Pain creates hyper vigilance. That's why they pace at 2 AM.

Cognitive Decline

Cognitive Decline

Dogs with pain develop dementia symptoms 40% faster.

The Decade Dog™ Solution?

Our custom formula reduces the brain inflammation CAUSING pain signals. When inflammation drops, body wide pain is reduced and your dog finally has energy for YOU again.

Frequently Asked Questions

Vet prescriptions for cognitive decline (Anipryl) cost $100 to $300 per month plus vet visits and bloodwork. Generic chews at $43 use crappy diluted, multi-purpose formulas with no clinical dosing. Decade Dog™ gives you clinical-strength cognitive support at a fraction of prescription cost with a 90-day guarantee if you are not satisfied. NO other brand does this.

Yes. Decade Dog™ complements joint supplements, fish oils, and most other supplements. If your dog is on prescription medications, check with your vet first. There are no known interactions with common senior dog medications.

Most owners notice increased alertness and engagement within 2 to 4 weeks. This is the proof window. Full cognitive benefits from Lion's Mane develop over 8 to 24 weeks with continued use. The supplement is designed for long-term daily use.

Yes. All ingredients are dosed for safe, ongoing daily use. Every ingredient is at least 752,000x below any toxicity threshold. Slippery Elm is included specifically to support gut health during long-term use.

Our liquid formula has natural beef liver flavor that even picky eaters love. It mixes invisibly into wet food or broth. In 4,800 plus dogs served, picky eating has been a non-issue. But if it does not work for your dog, you are covered by our 30-day guarantee.

Absolutely. They complement each other perfectly. Body plus brain equals more good years. Many of our customers use Decade Dog™ alongside glucosamine, fish oil, and other joint support.

Decade Dog™ has no known interactions with common senior dog medications. We recommend spacing the dose out at least 3 hours from any medication to avoid competition of nutrients and best absorption. If your dog is on anticonvulsants, blood thinners, or has chronic kidney or liver disease, consult your veterinarian first.

30-day, 100% money-back guarantee. If you do not see improvement, email us for a full refund. No return shipping required. No questions asked. We have served thousands of dogs with less than .8% return rate.

Your order ships automatically each month so you never run out. You can pause, skip, or cancel anytime from your account dashboard. No phone calls, no hassle. Most customers stay because it works, not because they are locked in.

The best time to start is before you notice problems. Cognitive changes begin around age 7, even if invisible.

Decade Dog™ is formulated for dogs 5 and older. This is JUST before when cognitive changes typically begin, even if you do not notice them yet. Starting early provides the best preventative benefit. Dogs showing active cognitive decline at any age can benefit.
