dog sitter reveals the daily habit behind dogs living 17–20 years

Published on 14/03/2026 By Linda Thompson, Professional Dog Sitter (27 Years Experience)

"After watching hundreds of dogs grow old and pass away… I finally realized the difference between the ones who live 8–10 years and the ones who reach 17, 19, even 20."

Dear dog parent,

My name is Linda Thompson.

I’m 58 years old, and I’ve been a professional dog sitter in Ohio for the last 27 years.

Over that time I’ve cared for thousands of dogs.

I’ve watched puppies grow into seniors… and seniors eventually pass away.

It’s the cycle every dog owner learns to accept.

Most dogs slow down around 8 or 9.

Many develop heart problems not long after.

By 10 or 11, many families are preparing to say goodbye.

That’s just the way things are.

Or at least that’s what I believed.

Until I met the Warren family.

The Family That Broke The Cycle

I started sitting for the Warrens in 2015.

They traveled often. Two weeks in spring, a month every summer, holidays with family.

They had four dogs.

Buster.
Chester.
Penny.
And Mabel.

The youngest was already 11 years old when I first met them.

The oldest was 16.

I remember thinking:

“These dogs are ancient.”

I assumed I’d watch them pass away over the next few years.

But something strange happened.

Every time I came back to their house…

They were still there.

Still wagging.

Still happy.

Buster turned 12. Then 13. Then 14.

Chester hit 15… then 16.

Penny reached 17 and still chased squirrels.

And Mabel, the dog who was already 16 when I met her, lived to 19.

Meanwhile, my own dogs were dying young.

The Pattern I Couldn't Ignore

My first dog, Honey, died at 8.

Heart failure.

My second dog, Duke, made it to 9.

Heart problems again.

Then my third dog, Rosie, died at just 7.

The vet told me her heart had become severely enlarged.

Three dogs.

All gone before 10.

And every few months I’d walk into the Warrens’ house…

And see four dogs still alive at 14, 16, 17, even 19.

I started wondering:

What were they doing differently?

The Morning Routine That Changed Everything

For three years I followed Mrs. Warren’s instructions exactly.

Every morning I would:

Let the dogs outside.

Refill their water bowls.

Measure their food.

And then add one scoop of white powder to each bowl.

Every dog. Every meal.

Mrs. Warren had written it clearly in the instructions:

“Don’t skip it.”

So I never did.

But for three years, I never asked what it was.

The Question That Changed My Life

Then Rosie died.

My sweet, healthy dog… gone at 7 from heart failure.

I sat in the vet’s office holding her collar and wondering:

What am I doing wrong?

And the next week I was back at the Warrens’ house.

Four dogs. All over 14 years old.

Still healthy.

Still happy.

That’s when I finally asked.

“Mrs. Warren… that white powder I put on their food every morning… what is it?”

She looked at me like the answer should have been obvious.

“Taurine,” she said.

“You don’t give your dogs taurine?”

I had never even heard of it.

The Nutrient Most Dog Owners Never Hear About

Mrs. Warren sat me down at her kitchen table and explained something that completely changed the way I think about dog health.

Dogs need taurine.

It’s an amino acid their bodies use to support:

• Heart function
• Eye health
• Muscle strength
• Overall vitality

Dogs can produce some taurine naturally.

But often not enough.

And many modern dog foods only contain the minimum needed to prevent immediate problems, not enough to support the heart long term.

So every day, many dogs slowly run a deficit.

A little lower.

A little weaker.

Until eventually the heart struggles.

And that’s when owners start noticing symptoms.

What I Discovered After Researching It

After that conversation, I went home and started researching everything I could find.

What I discovered shocked me.

Many breeders and working dog organizations have been supplementing taurine for decades.

Some shelters even use taurine supplementation protocols.

Because when dogs consistently receive enough taurine, their hearts stay stronger for longer.

The Warrens had known this for years.

And their dogs were living proof.

The Change I Made

The next time I adopted a dog, I did something different.

On the very first morning, I added a scoop of taurine to her food.

Just like Mrs. Warren had taught me.

That dog lived to 18.

Then came Max.

He made it to 17.

Then Daisy, 19 years old.

Then Cooper, 17.

Every single one lived far longer than my earlier dogs ever had.

And the only real difference was one daily scoop.

What Many Dog Owners Are Doing Now

Today, many dog owners add taurine directly to their dog’s meals.

One option many people choose is PurePaw Taurine.

It’s a taurine supplement made specifically for dogs.

Owners simply add a small scoop to their dog’s food each day.

That’s it.

It takes about 10 seconds.

And it helps support the nutrient many dogs may not be getting enough of from food alone.

The Difference One Small Habit Can Make

After nearly three decades caring for dogs, I’ve seen two different paths.

Most families lose their dogs around 9, 10, or 11.

But occasionally I see families like the Warrens.

Dogs living to 17… 19… even 20 years old.

The difference isn’t luck.

Often, it’s the small things done consistently over time.

The Choice Every Dog Owner Faces

Right now, your dog is either:

Receiving the nutrients their heart needs to stay strong

OR

Slowly missing something essential for long-term heart health.

Most dog owners believe their dog’s food provides everything they need.

But sometimes the smallest gaps in nutrition can matter the most.

Taurine is one of the simplest gaps to address.

What Do Others Say About The PurePaw Taurine Supplement

"My 7-year-old Golden Retriever, Buddy, was diagnosed with early signs of heart enlargement at his annual checkup. Our vet mentioned taurine deficiency as a possible factor and suggested we look into supplementation. We started PurePaw within the week. Three months later, his follow-up echo showed his heart had stabilized. His energy is back to what it was two years ago — he's running in the yard again like a puppy. I wish I had started this sooner."

— Jennifer M. ★★★★★

"Buster stopped finishing his walks a few months back and I figured it was just age catching up with him. Vet found his taurine was low and his heart was working harder than it should be. Started PurePaw and within a few weeks he was back to following me everywhere around the house. His follow-up bloodwork came back much better. Simple fix honestly, just wish I had caught it sooner."

— Laura K. ★★★★★

"My Dachshund Rosie had a grade 2 murmur show up at her last checkup. Vet recommended taurine support so we started PurePaw. She's more active now than she's been in over a year. Still keeping up with her checkups but so far so good. Mixes right into her food and she doesn't even notice it's there."

— Patricia L. ★★★★★
