Frequently Asked Questions

Everything you need to know about Decade Dog™, answered by our team.

General FAQs

Is the price really worth it?
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.
Is it safe to use with other supplements?
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.
How long until I see results?
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.
Is it safe for long-term 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.
What if my dog is picky?
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.
Can I use it with joint supplements?
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.
My dog is on prescription medication. Is this safe?
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.
What is your return policy?
90-day, 100% money-back guarantee. If you do not see improvement, email us for a full refund. You must return any used, full or empty bottles along with any extras received (to help prevent fraudulent returns) We have served thousands of dogs with less than .8% return rate.
How do auto-refills work?
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.
My dog seems fine. Is it too early to start?
The best time to start is before you notice problems. Cognitive changes begin around age 7, even if invisible.
What age should my dog start?
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.

About the Product

What does it taste like?
Premium natural beef liver flavor. Even picky eaters love it. It mixes invisibly into wet food or broth. The ingredients are human grade, try it yourself!
Does it need to be refrigerated?
Not in tepid climates. Store at room temperature in a cool, dry place. Keep the cap tightly closed. If you are in a HOT climate, we do suggest refrigerating to prolong the shelf life.
What's the shelf life?
2 years from manufacture date. Expiration date printed on every bottle.
Are there any fillers or artificial ingredients?
Nope! No artificial colors, flavors, or preservatives. All inactive ingredients are organic and food-grade.
Is it safe for puppies?
Decade Dog™ is formulated for dogs 5 years and older. Not recommended for puppies or young adult dogs.

Safety & Dosing

What if I accidentally give too much?
Our ingredients have extremely high safety margins. An accidental double dose is not dangerous, but stick to recommended dosing for best results. Your dog may have an upset tummy.
Can I split the dose between morning and evening?
Yes! This is actually recommended by the vet team, however sometimes it hard to get customers to stick to 2x per day :) Otherwise, we recommend giving the full daily dose in one serving for maximum absorption, ideally with their main meal.
What if my dog misses a dose?
Just continue with the next scheduled dose. Don't double up. Consistency matters more than perfection.
Can multiple dogs share one bottle?
Yes, if they're similar sizes. Adjust dosing based on each dog's weight using the dosing chart.
My dog has kidney disease. Is this safe?
Consult your veterinarian before starting any supplement if your dog has chronic kidney disease, liver disease, or is on blood thinners or anticonvulsants.

Results & Expectations

What if I don't see results in 30 days?
Most owners notice improvement within 2-4 weeks, but full benefits develop over 8+ weeks. If you're not satisfied at any point within 30 days, contact us for a full refund.
Will this cure my dog's dementia?
Decade Dog™ is a supplement, not a cure. It supports cognitive function and may slow decline, but cannot reverse severe dementia. Best results come from early intervention.
Can I stop once I see improvement?
Cognitive support requires ongoing daily use. Stopping the supplement means stopping the support. Think of it like joint supplements - they work as long as you use them.
My dog is on Anipryl. Can I use both?
There are no known interactions, but we recommend spacing doses 3+ hours apart and consulting your vet to avoid redundancy in your treatment plan.
