Dogs don’t get enough years
& enough healthy ones.

Then we looked at the products meant to help: boring brands, basic formulas, fairy-dust doses, mystery blends and a lot of wellness bullshit. Products made to sound effective, without doing nearly enough for the dog.

We thought dogs deserved better. Better science. Better formulas. Better days now and more good years with us.

So we built one: a serious, whole-dog longevity formula in a daily bar they’ll actually want to eat.

Daily longevity bar for dogs.

Mortal. But we’re working on it.

One soft bar a day. 43 actives at amounts we print in full — mobility, digestion, calm, immunity, healthy aging — and they think it’s a treat.

$6.90 today · then $89 / 30 days · 7 days to send it back

This is the entire routine.

Offered. Taken. Gone.
Two dogs. One bar each. No cheese.
One offer. Then the lip lick.

43 actives

4,269 mg of them

Tested every lot

No mess

One bar a day

Nothing to hide.

All 43 actives, each with its amount. 4,269 mg a day — more than a capsule holds, and why it’s a bar.

    Per daily bar — Medium (25–60 lbs). Small and Big bars are scaled to size.

    Inactive ingredients: chickpea flour, pumpkin, natural chicken flavor, glycerin, sunflower lecithin, mixed tocopherols (preservative).

    Better poops.Same intense eye contact.Supports healthy digestion, regularity and a balanced microbiome — 2 billion CFU, plus the prebiotic fiber that actually feeds them.
    Less postman drama.Same unpaid security job.Supports calm behavior and easier settling when everyday life gets loud — magnesium in the glycinate form, because calm shouldn’t cost them the gut.
    More yes to walks.Same 12-minute sniff.Supports joints, muscles and comfortable everyday movement — six joint actives, led by HCl-form glucosamine and marine omega-3 over plant oils.
    Healthier coat.Same love of mud.Supports healthy skin and coat from within — chelated zinc, because oxide forms mostly pass straight through.
    Sharper mind.Same selective hearing.Supports cognition and healthy brain aging — marine DHA and methylated B-vitamins, in the forms the brain can use directly.
    More good years.Same bathroom escort.Supports immune and cellular health, and whole-body healthy aging — the cellular layer, dosed rather than dusted.

    Serious science.
    For someone
    who eats socks.

    The everyday stuff + the long‑game stuff.
    Finally in one formula.

    One bar replaces 13 supplements: probiotic, joint chew, fish oil, skin and coat, calming chew, multivitamin and seven more. Your dog is aware of one.

    Because a healthier dog often starts in the gut. Better poops help too.

    Key actives

    Probiotic blend (L. acidophilus, B. animalis) · prebiotic inulin & FOS · digestive enzymes · pumpkin fiber · microencapsulated tributyrin

    Why these forms

    Spore-stable strains survive the bar and arrive alive. The fibers are what feed them.

    Because the sofa should remain a choice, not a limitation.

    Key actives

    UC-II® undenatured collagen · glucosamine HCl · chondroitin · MSM · marine omega-3 (EPA/DHA) · green-lipped mussel · ultra-micronized PEA

    Why these forms

    HCl-form glucosamine for absorption, marine omega-3 over plant oils — six joint actives, not one.

    Because scratching shouldn’t be a full-time job.

    Key actives

    Omega-3/6 balance · chelated zinc · biotin · vitamin E

    Why these forms

    Chelated zinc absorbs where oxide forms mostly pass through; natural-source vitamin E protects the fats.

    Because the doorbell is not an emergency.

    Key actives

    L-theanine · ashwagandha · magnesium glycinate · chamomile

    Why these forms

    Magnesium in the glycinate form: calm that doesn’t cost them the gut.

    Because more years are better when they still want to use them.

    Key actives

    Active B-complex · ubiquinol + PQQ · L-carnitine · taurine

    Why these forms

    Active B-forms skip a conversion step; carnitine and CoQ10 fuel the mitochondria.

    Because their defenses don’t take weekends off.

    Key actives

    Beta-glucans · vitamin D3 · colostrum · selenium · vitamin C

    Why these forms

    D3 over D2, yeast-derived beta-glucans. Most immune tissue lives in the gut, so this leans on the microbiome work.

    Because every good walk starts with the engine.

    Key actives

    Taurine · marine omega-3 (EPA/DHA) · ubiquinol · L-carnitine

    Why these forms

    Taurine and carnitine are the classic heart pair; ubiquinol supports the muscle itself.

    Because staying themselves is the whole point.

    Key actives

    DHA · phosphatidylserine · lion’s mane · methylated B-complex · blueberry antioxidants

    Why these forms

    DHA over plant omega-3, and methylated B-forms the brain can use directly.

    Because aging happens one cell at a time.

    Key actives

    NMN · urolithin A · liposomal fisetin · spermidine · resveratrol · alpha-lipoic acid · astaxanthin

    Why these forms

    The actives human longevity research is built on, at amounts worth printing. That room is why this is a bar.

    Because strength matters long before old age looks obvious.

    Key actives

    Collagen peptides · calcium + D3 + K2 · leucine-rich protein

    Why these forms

    K2 directs calcium to bone, not soft tissue.

    Because somebody has to handle the questionable decisions.

    Key actives

    Milk thistle (silymarin) · curcumin · quercetin phytosome · glutathione precursors

    Why these forms

    Silymarin is the best-studied liver botanical; curcumin in a form that actually absorbs.

    Because healthy aging includes the organs nobody posts about.

    Key actives

    Cranberry extract · taurine · omega-3 · selenium

    Why these forms

    Cranberry for urinary support; taurine and omega-3 for the kidneys — the parts nobody thinks about until they matter.

    Dogs can’t type.
    Their humans have notes.

    Why we built this.

    Dogs don’t live long enough. And too many spend too much of their already-short lives not feeling their best.

    Then we looked at the products meant to help: boring brands, basic formulas, fairy-dust doses, mystery blends and a lot of wellness bullshit. Products made to sound effective, without doing nearly enough for the dog.

    We thought dogs deserved better. Better science. Better formulas. Better days now and more good years with us.

    So we built one: a serious, whole-dog longevity formula in a daily bar they’ll actually want to eat.

    No mystery blends. No token ingredients. No bullshit.

    Today you pay $6.90 — that’s the shipping. The full first box leaves within 1–2 business days, and your 7 days start the day it’s delivered, not the day you order.

    If it’s a no, cancel online and we send a courier for the box — you owe nothing more. If it’s a yes, the subscription starts on day 7: $89 every 30 days, with your $6.90 credited to the first charge ($82.10). Pause or cancel online any time; we email you before every charge.
    Because 43 actives at real doses cost more to make than a chew that’s mostly binder. The expensive part is the list — NMN, Urolithin A, marine omega-3, UC-II®, ubiquinol — in the forms that work, at amounts we print on the label.

    Bought as separate bottles, six of those actives alone already cost more than the whole bar — and that’s six of forty-three. Per day it’s $2.97. If it isn’t worth it, the first 7 days cost you $6.90 in shipping and nothing else.

    Your first box costs $6.90 to ship and leaves within 1–2 business days. Every box after that ships free in the US. Not for them? Cancel in the first 7 days and a courier collects the box — nothing more to pay.

    Digestion is usually first (1–2 weeks). Coat, movement and calm typically follow over 4–8 weeks. Every dog is different — longevity is a long game.

    You don’t — we do. Tell us their weight and we match the bar: Small (under 25 lbs), Medium (25–60 lbs), Big (over 60 lbs). Every sachet is pre-portioned to that size.

    The bar is built to replace the everyday stack. If your dog takes medication or has a health condition, check with your vet first.

    Room temperature, in the box. Each bar is individually sealed, so it stays fresh until the day you tear it open.

    One full bar per dog, per day.

    Tell us their current weight and we’ll match them to the right bar size. If their weight changes, update their plan.

    Each dog needs their own correctly sized bar. Sharing is sweet. Incorrect dosing isn’t.
    Morning or evening both work. Give it with or just after a meal, at a time you can stick to.

    Consistency matters more than the clock.
    Skip the guilt. Don’t double the next serving.

    Simply continue with one bar the following day.
    No. One correctly sized bar contains their full daily serving.

    The face they’re making is not dosing guidance.
    Give one bar every day for at least 90 days before judging results — the first 7 days are about whether they’ll eat it, not whether it’s working yet.

    For continued support, keep it as part of their daily routine.
    No. It’s a daily supplement and should be given alongside their usual complete and balanced diet.

    According to your dog, however, it is absolutely a treat.
    Speak with your veterinarian before starting if your dog takes medication, has a diagnosed medical condition, is pregnant or nursing, or is not yet an adult.
    That’s what the sachets are for.

    Pack one for each day and leave the tubs, scoops and leaking fish oil at home.
