How this started

In her words.

January 2021

She started Bucket and Dagwood on it.

"Those supplements GENUINELY changed Dagwood's life and I was so excited to share them with you all."
Then

Then she shared it.

"And when I did share them…y'all bought the whole internet CLEAR OUT OF STOCK 😂"
So

She wrote to us.

"I have never before reached out to a company on this app wanting so desperately to work with them…"
Since

We've been grateful ever since.

We're a small team. Five years on, her pack is still on it, and you keep asking her what it is.

For Dagwood, who started all of this. 🕊️

In your words.

What you sent Brianna, after she shared it. She posted these on her stories.

to @briannamadiaThese supps make a WORLD of difference for my dogs too!! I started using them when you shared and holy sh*t they r magic

to @briannamadiaI had my boy on a different brand and he just acted sluggish and like he didn't feel good. Since switching he acts like a puppy. And I'm so thankful.

to @briannamadiaWe've been giving them to our dogs for years because of you ❤️❤️ thank you!

to @briannamadiaMy oldest who is 10 you can really see a difference in the way he gets up and lays down. More pep in his step.

Why will this work?

When other chews haven’t.

  1. 1

    Ultra high strength formula

    Most chews are dosed to maintain a healthy joint. This one is dosed to rebuild a worn one.

    1,500mg
    2,300mg
    3,200mg

  2. 2

    Calms inflammation first

    As a dog ages, the body stops keeping up with daily wear. That damage turns into inflammation.

    While the inflammation is there, the joint breaks down faster than it can rebuild.

  3. 3

    The dose on the label is the dose in the tablet

    Every ingredient is tested with a spectrometer before production. So 3,200mg means 3,200mg.

Here’s what recovery looks like

Days 1–7Less hesitation getting up. Less stiffness.
Weeks 2–4Easier mornings. More comfortable walks.
Weeks 4–8Takes stairs easier. More energy through the day.
Weeks 8–12Jumping up. Greeting you at the door again.

Every dog responds on their own timeline. These are typical patterns gathered from hundreds of customer reports.

What’s actually in the bottle

Why we made this

Vetrinex started with my own dog. Caesar, my German Shepherd, began slowing down, and I couldn’t find a joint supplement dosed to actually work. So we built one. Since 2015 we’ve helped 100,000+ dogs, and it stays personal: we only win if your dog does.
