From Dr. Christine & Dr. Jeremy
We Need To Tell You Something.
And we wish someone had told us sooner.
You know the morning.
You wake up, and before you even make coffee, you’re listening. Waiting to hear whether he can get up on his own.
Some mornings he makes it. Some mornings you have to go in and help lifting his back end gently, the way you’ve practiced.
But you know it’s getting worse.
The stairs he used to fly up. The door he used to sprint to when he heard your key.
Now you come home and he’s still lying where you left him.
Wags once. Stays where he is.
Because getting to the door costs too much.
You got glucosamine.
And he is still struggling to get up.
Maybe you switched brands.
Maybe you’ve been doing this for months. Maybe years.
And he is still struggling to get up
You didn’t do anything wrong. Glucosamine did.
And we know because we made the same mistake.
You’re Not Alone in This
It wasn’t too late for any of their dogs. It’s very likely not too late for yours.
How My Own Dog Changed Everything
I’m Dr. Christine. I’ve been a veterinarian for 15 years across three continents. In my early career, I recommended glucosamine without a second thought.
“Get her on a good joint supplement. Give it time.”
Until my own dog, Pepsi, proved me wrong.
Veterinary-grade glucosamine.
Proper dosing.
Every protocol followed.
Two months later,
Pepsi was worse.
So I went back to the published research — not the manufacturer summaries, not the continuing education sponsored by supplement companies.
The actual peer-reviewed studies.
85 of them.
And what I found completely invalidated the "Gold Standard" of joint care—and revealed exactly why Pepsi was still struggling.
Here’s What We Discovered & Why We Built Jope
For 30 years, the assumption was simple: Cartilage wears down, you add building blocks, it rebuilds.
That was glucosamine’s entire theory.
Wrong.
When cartilage breaks down, fragments float into the joint fluid. Your dog’s immune system treats them like a foreign invader and launches an immune response against his own joint tissue.
More damage triggers more immune response. More immune response causes more damage.
His body is working against itself.
Glucosamine tries to rebuild from the outside while the immune system tears it apart from the inside.
Like patching a wall while someone is actively knocking it down from the other side.
It never stood a chance.

It never stood a chance.
Every major clinical trial for 15 years reached the same verdict: it doesn't work.
The industry kept selling it anyway. Because it’s cheap. Because the name sounds scientific.
Because nobody told you there was something else.
That is not on you. The gap wasn’t in your effort. It was in the ingredient.

The "Repair Signal" The Pet Industry Ignored.
When I finally dug into 85 clinical trials and raw research data, the truth was hiding in plain sight: the industry had been targeting the wrong mechanism for decades.
But buried in those same studies was a biological "Repair Signal" that worked through the immune system directly.
It didn't just beat the "Gold Standard."
It outperformed glucosamine by 59%!
I immediately called Dr. Jeremy—my co-founder and fellow Veterinarian—and told him:
"The industry is wrong. We have to build this ourselves."
The Ingredient We Built Jope Around
The ‘Biological Repair Signal’ is called UC-II® — undenatured type II collagen.
UC-II® interrupts the immune attack at the source.
It reaches a specific region of the small intestine and does something glucosamine never could:
it teaches the immune system to recognize joint cartilage as safe.
Not a threat. Not an invader. Safe.
The cells that were attacking the joint convert into protective cells.
The attack slows.
The vicious cycle slows downs
The cartilage stabilizes.
What We Put in Jope and What We Left Out
Jeremy and I asked one question: if we could only include what’s been proven in objective clinical testing, what would be in this?
What We Left Out:
❌ Glucosamine.
❌ Chondroitin.
❌ MSM.
We could have added them. But the studies said they don’t work. So we refused.
And Pepsi — my dog?
He ran again.

Why Jope Outperforms The Rest
What Our Customers Tell Us
Stephanie helped Beverley feel strong again
“Bev is a senior and started to be stiff with her hind legs a year ago. My vet recommended starting Jope. I saw fast improvements, and Bev was back to her old happy self in no time!”
— Stephanie S.
Jope allows Pai to enjoy her youth!
“Pai had surgery when she was ten months old. Since then, my priority has been keeping her joints strong and healthy, so my vet recommended Jope. Pai loves her joint chews!"
— Julien H.
Everything You’d Hope To See Change
“Bella jumped on the sofa next to me for the first time this year. I burst into tears.”
— Gary K.
What did "affordable" glucosamine cost you?
Less than what you were spending on glucosamine that no longer works
The months of waiting.
The second, third, and fourth failed brands.
The vet visits where nothing changed.
That is the real cost of outdated science.
It’s a fraction of a single vet visit. And while past cartilage damage can't be reversed, the immune attack can be stopped today.
UC-II® - the only joint supplement ingredient objectively proven to work in dogs.
But it can't repair the days you wait to start.
The best time to switch was the day you realized her old chews weren't working.
The second best time is right now.

Our Guarantee to You
90 days. Not 30. Ninety.
Watch your dog every morning. Notice what changes.
If at any point you feel like it’s not working — email me personally at contact@petjope.com.
One email. Full refund. No questions, no forms, no sending back the bag.
We’re not worried about refunds.
We’re worried about the dogs still on glucosamine.
A few weeks from now.
You’re in the kitchen. Coffee still brewing. And you hear her.
Not the shuffle. Just footsteps — moving down the hallway with purpose.
She comes over. Puts her head on your knee.
She hasn’t done that in months.
A few mornings later — paws on the floor, the full-body welcome, the tail that goes before the rest of her has decided what to do with itself.
She’s there. At the door. Like she used to be.
You stopped giving her what the industry told you to buy.
And you started giving her what the science — and two vets who’ve been exactly where you are — say actually works.
Frequently Asked
Questions
My vet still recommends glucosamine. Should I be concerned?
No. Glucosamine has been the default for decades. Shifting practice takes time. We made that shift after 85 peer-reviewed studies. A growing number of colleagues are following.
Is my dog too old?
For most dogs, no. Some of our most dramatic results come from dogs aged 10–13. The mode of action UC-II addresses is still active regardless of how long the arthritis has been progressing.
When will I see a difference?
Every dog is different. Some owners notice changes within a couple of weeks. Others takemore. The best results arrive in 2 to 3 months. That’s why we give you 90 days, not 30.
Can I switch directly from glucosamine?
Yes. No transition needed.
What if it doesn’t work?
Email contact@petjope.com within 90 days. One email. Full refund. No hoops.
Will my dog eat it?
Almost certainly. Natural flavor. Over 90% love the state. And if not, you’re fully covered by our 90-day guarantee.
How much does my dog need?
Under 25 lbs: 1 chew daily. 25–75 lbs: 2 daily. Over 75 lbs: 3 daily.
Who are you?
We’re Dr. Christine and Dr. Jeremy — both veterinarians, friends from vet school, co-founders of Jope. We created it after my dog Pepsi couldn’t be helped by glucosamine. Made in Midwest, cold-pressed, third-party tested.
