UPDATED 5/20/2026: Demand from owners of dogs 7+ has been unprecedented this month. Bottles are shipping in 24-48 hours while supply lasts.

You take care of yourself.
You read about NAD+, NMN, resveratrol. You know that David Sinclair at Harvard, Peter Attia, Rhonda Patrick — every longevity researcher on the planet — agrees: cellular aging starts in adulthood, not at the end of life. You take the supplements. You eat the food. You're aware.
Then you look at your dog.
He's 7. Maybe 8. The vet still calls him "adult," not "senior." But you see it. You see him pause at the stairs before he goes up. You see him circle the bed three times before he can settle. You see the thousand-yard stare some afternoons — the moment where he's awake but nobody's home behind his eyes.
And the worst part? Nobody told you this would start happening at 7. You thought you had years. You thought aging was something that hit at 11 or 12.
It's not. It started earlier. It started at the cell level. And the same longevity research you're reading for yourself was published for dogs years ago — your vet just isn't telling you.
Every cell in your dog's body runs on a molecule called NAD+.
Think of it as the spark that turns food into life — the fuel that powers his brain, his back legs, his heart, his immune system, his coat. Every single thing his body does, NAD+ pays the bill.
Here's the problem science discovered around 2013, and the dog world is just now catching up to:
NAD+ levels drop by up to 50% by the time a dog is middle-aged. The cells don't run out completely — they just start running on half. Half the energy. Half the repair speed. Half the alertness.
That's why your 7-year-old isn't "lazy." He's running on half a battery. He's not depressed. He's energy-starved at the cellular level. And no joint chew, no fish oil, no "senior food" can refill that tank — because none of them contain the precursor his body needs to make NAD+ again.
The discovery that changed everything? A molecule called NMN (nicotinamide mononucleotide). When you give it to an aging mammal, the body uses it to make NAD+ again. Cells re-energize. Mitochondria turn back on. The system reboots.
This isn't hype. This is the same compound David Sinclair takes himself. The same compound now backed by peer-reviewed canine RCTs published in 2024 and 2025.
"He's only 7 and the spark is just gone. He's not in pain. He's just... not there anymore. I miss the dog he was a year ago."
"I take NMN and resveratrol every single morning. Why is my dog still on a $12 joint chew from the grocery store? I felt like such an idiot when I realized what I was doing."
"The vet said he's healthy for his age. But he's not the dog he was a year ago. The thousand-yard stare in the afternoons is the worst part. Like he's looking at me from somewhere far away."
"He used to lose his mind when I came home. Now he lifts his head, wags twice, and goes back to sleep. He's 8. Eight."
"I'm not ready. I am not ready for him to be the slow one yet. He's supposed to have years."
In 2024, Simon and colleagues published a randomized controlled trial in Scientific Reports on 70 senior dogs given a senolytic plus NAD+ precursor protocol.
At 3 months, owners reported a statistically significant improvement in cognitive function (p=0.02). The dogs who used to stare at walls came back. The dogs who used to forget the family came back.
That same year, Zeng and colleagues published in Aging Cell that NMN improved cardiac function and lowered inflammation markers (IL-6, TNF-α) in aged dogs.
Tvarijonaviciute and colleagues (2022, Antioxidants) found that CoQ10 reduced cardiac injury markers in 71% of dogs with heart disease, with systolic function improving 8-9%.
Bian and colleagues (2025, Antioxidants) showed that 35 days of resveratrol restored serotonin, BDNF, and gut microbiome balance in dogs under chronic stress.
This isn't "someone heard about NMN on a podcast." This is peer-reviewed canine evidence — and it's been building for years. The reason your vet hasn't talked about it is that the veterinary clinic system is 5-10 years behind the longevity research curve.
The dogs in those studies didn't get pills. They couldn't have. Pills don't survive the dog's digestive tract intact. That's where the next piece comes in.
This is the single biggest reason owners try NMN chews and see "nothing happens." The chew works. The dog ate it. But the molecule never made it past stomach acid and liver first-pass metabolism. It got destroyed on the way.
Zabielska-Koczywąs and colleagues (2017, Molecules) confirmed that liposomal and nanoparticle delivery systems dramatically improve drug bioavailability in dogs and cats. A 2025 PMC review confirmed that nanoliposomal systems protect compounds from GI degradation, enhance transepithelial absorption, and bypass liver first-pass metabolism entirely.
Translation: the molecule actually gets to the cells. That's the entire reason Pawprint Protocol is a liquid in a dropper — and the reason owners see changes in 3 to 5 days instead of "maybe in a few months, who knows."
Four active ingredients. One delivery system. All four chosen because the canine research is now strong enough to publish in peer-reviewed journals — not because they sound good in marketing copy.
Why all four together, in a nanoliposomal liquid?
✔ NMN feeds the system. NAD+ supports it directly. Resveratrol activates the genes. CoQ10 powers the engine. Take one out and the others can't do their job.
✔ Nanoliposomal delivery means up to 5-10x more actually reaches the cells vs. pills or chews
✔ One dropper into food — no pill battles, no chews spat out, no "did he actually eat it"
✔ Vet-formulated, third-party lab tested, made in the USA
✔ 90-day money-back guarantee — with less than 1% of customers ever claiming it
The timeline owners see — based on more than 100,000 dogs across thousands of verified reviews. Visible changes start faster than most owners expect, because nanoliposomal delivery puts the molecule in the bloodstream within hours.
"I take NMN. My husband takes NMN. We're both 50-something and we read Peter Attia. One night I looked at Bear — he's 9, black lab — and I realized we were giving him a generic chew while we were on the real stuff. I felt sick. We started him on Pawprint Protocol that week. By day 4 he started leaning on me at the counter again. He stopped doing that two years ago. I didn't realize how much I missed it until he started again. He's the same dog. He's just here again."
"Vet said Cooper was healthy for 7. But I knew. The vacant stare in the afternoons was the worst — like he was awake but somewhere else. After 5 days on the drops he jumped on the bed without thinking about it. We both froze. He hasn't done that since the spring. The peer-reviewed canine NMN research finally has a product behind it that actually delivers the molecule."
"I'm 51. I have a whole shelf of longevity supplements for me. I read Sinclair's book twice. It took me embarrassingly long to realize my 8-year-old Goldendoodle should be on this too. Two months in, Murphy is doing zoomies in the yard again. My husband actually asked 'when did he turn back into himself?' I cried. We are not ready to lose him. We have more time now. That is what this protocol gave us. More time."
Loved by 100,000+ dogs. Rated 4.8/5 stars across thousands of verified reviews. Backed by a 90-day money-back guarantee with less than 1% claim rate — most owners see changes in the first week and never look back.
You don't need to wait until he's "old" to start. The whole point of cellular longevity science is to start before the damage compounds. The dogs who do best are the ones whose owners caught it at 7, 8, 9 — not the ones who waited until 12.
You're already doing this for yourself. He's been waiting for you to do it for him too.
Start now — before the next thousand-yard afternoon. Your dog is only as young as the cells you fuel today.
