Dear Friend With a Senior Dog,

If you’re reading this while your dog sleeps most of the day away…

If you’ve started helping him up off the floor in the morning…

If his back legs slide out from under him on the kitchen tile, night after night…

Then what I’m about to share could save you months of worry — and a small fortune on things that never quite worked.

But I’ll be honest with you first.

What you’re about to read might make you a little angry.

Not at your vet. Not at anyone.

Angry that no one ever explained the simple thing sitting underneath it all.

My name is Dr. Mark Saraiva.

I’m a veterinarian, and I helped formulate Pawprint Protocol.

For years I treated dogs who were slowing down with age, and I watched good owners try everything they were told to try.

And until one case a while back, I thought I understood why so many of them kept coming back.

The Case That Changed How I Practice

I’ll call the dog Bear.

His owner, Linda, brought him in after she found him one morning unable to get up off the kitchen floor.

His back legs had slid apart on the tile and splayed out under him. He couldn’t get his feet back beneath himself.

She had to lift him by the hips just to get him standing.

He was ten. A year before, he met her at the door every single day. Now he barely lifted his head.

“I can’t watch this,” she told me. “I’ve tried everything and nothing holds.”

Linda wasn’t a careless owner. She was the opposite.

She had done every single thing she’d been told to do.

And here’s what wore her down:

  • The joint chews? They eased the stiffness for a while — then he was slowing down all over again.
  • The “senior” food? Months on it. He still slept the whole day away.
  • The supplement powder? She mixed it into his bowl every night. Nothing changed.
  • The vet check-up? His bloodwork looked “fine for his age.” No answers — just “keep him comfortable.”

Every one of those things has its place. Some of them gave Bear real relief.

But not one of them was aimed at the thing his body was actually missing.

That night, something in me shifted.

I wasn’t going to send another owner home with one more thing that only quiets the surface.

I went looking for the real reason.

The Thing Nobody Explains About a Dog Slowing Down

For weeks I read everything I could find on how dogs age.

And what I found was so simple it almost made me upset I’d missed it for so long.

Most senior support only quiets the signs. It doesn’t refuel where aging actually begins — inside the cells.

Think of it this way.

Every part of your dog runs on energy — his back legs, his heart, his memory.

That energy is made inside his cells, in tiny engines called mitochondria.

To run, those engines need a spark. That spark is a molecule called NAD+.

When your dog is young, he’s full of NAD+. The engines hum. He runs, jumps, and bounces back.

As he ages, NAD+ drops. The engines slow. Less energy reaches his legs, his heart, his brain.

That’s the slowing down. The shaky back legs. The long naps. The blank stare. The lost spark.

One running-low battery, showing up in different places at different speeds.

The Real Root Cause of a Dog Slowing Down

Picture a battery.

The battery is your dog’s cell. NAD+ is the charge that keeps it running.

Here’s the catch most owners are never told:

A dog’s NAD+ level falls naturally as he gets older. By his senior years it can be a fraction of what it was when he was a pup.

And here’s the part that wastes so much money: even when owners give the right nutrients, cheap powders and pills are poorly absorbed. Much of what you pay for never reaches the cells.

So the tank runs low and stays low. Slowly. Year after year.

The engines sputter. Less energy reaches the muscles that hold up his back legs. And the dog you knew starts to fade.

Research links healthy NAD+ levels and mitochondrial function to normal cellular energy and healthy aging.

Think about it.

You wouldn’t recharge a dead battery with a charger that was never plugged in.

You’d plug it in — put the charge back where the cell can actually use it.

That’s exactly what cheap, poorly-absorbed supplements miss, and exactly what I set out to fix.

The Simple Thing That Finally Helped

Once I understood the battery, the answer got simple.

To support a dog whose cells are running low, you need three things at once:

  • 1. RESTORE — put back the NAD+ the cells run on (with NMN and NAD+).
  • 2. FUEL — power the mitochondria, the tiny engines in every cell (with CoQ10).
  • 3. PROTECT — help shield the cells from the everyday wear that speeds aging (with Resveratrol).

Miss any one of them, and you’re only doing part of the job.

And here’s the part everyone misses: it has to actually absorb. A powder your dog can’t take in does nothing for his cells.

Remember Bear?

Weeks after Linda added it to his food — alongside what her vet advised, never instead of it — he started getting up on his own again.

His back legs felt steadier. He stopped sliding on the tile. He met her at the door.

Linda cried the first time he walked toward her on his own.

Why More Owners Are Talking About This

Word travels fast among dog people.

Once a few owners in my practice saw steadier legs and brighter eyes, they told their friends at the dog park. Those friends told theirs.

Soon I had owners I’d never met asking about “that senior thing.”

Not “managed it” better. Many of them simply noticed their dog moving and feeling like himself again.

Introducing Pawprint Protocol

It’s the liquid I helped formulate to do all three jobs in one daily dose.

Four research-backed longevity actives. And, just as important, it’s built to actually absorb — not a chew that’s mostly filler.

Restore the spark

NMN and NAD+ to restore the cellular fuel (NAD+) that powers everyday energy and repair.

Fuel the engines

CoQ10 to power the mitochondria — the tiny engines inside every cell.

Protect the cells

Resveratrol to help shield cells from the everyday wear that speeds aging.

(And it’s all delivered nanoliposomally — each active is wrapped in a tiny fat bubble so it slips into the body and actually reaches the cells, for up to 98% absorption. One daily dropper, dosed to your dog’s weight.)

What to Expect, Week by Week

Week-by-week what-to-expect timeline
Educational. Every dog is different; daily use matters.

Weeks 1–3: Many owners first notice a little more pep — getting up a bit easier, and more interest in what’s going on around them.

Weeks 4–6: Legs often feel steadier, walks last longer, and the “puppy trot” starts to peek through.

Weeks 6–12: The spark tends to feel like the new normal — steadier back legs, brighter eyes, and meeting you at the door again.

This isn’t a quick fix you feel in an hour. It’s the cells slowly getting back what they’ve been missing.

What’s Actually in Every Drop

The Real Cost of Watching Him Slow Down

Let’s be honest about what “just old age” usually costs.

Repeat visits, refills, special diets, joint chews and supplement after supplement add up fast — often hundreds of dollars a month, month after month, for a dog who keeps slowing down anyway.

Pawprint Protocol works out to roughly the price of a couple of coffees a week.

Not instead of your vet. Alongside good care — finally aimed at what his cells were missing.

Two Roads From Here

Two roads: keep waiting it out versus support the cells

Road 1: keep waiting it out. More naps. More lifting him off the floor. More “just old age.” A dog who keeps slowing down.

Road 2: support the cells themselves. One daily dropper that restores the cellular fuel, powers the engines, and protects the cells — while you keep working with your vet.

The choice seems pretty clear to me.

P.S. — Remember Bear? Linda told me the morning he got up on his own is what she noticed first. You’ll likely see it before anything else — the day you don’t have to help him off the floor.

P.P.S. — Pawprint Protocol is vet-formulated, third-party tested and made in the USA. We did it the right way.

P.P.P.S. — If your dog is still young and just starting to slow down, that’s the best time to support his cells — before the tank runs low. Don’t wait.
