Hey, I’m Bill!
Founder of WINPRO Pet
Over the years, I’ve owned and loved a lot of dogs. And at some point, every single one of them started showing the same signs:
It’s the hardest part of loving a dog. And it’s exactly why WINPRO exists.
When I was a kid growing up in Iowa, my dad brought home a beautiful Collie/German Shepherd mix named Yankee.
I didn’t have many friends back then... but Yankee became my best one.
If you’ve ever had “that dog,” you know exactly what I mean.
And like every dog I’ve loved since, Yankee got older. He still wanted to go. His body just wasn’t making it as easy anymore.
Back then, all I could do was watch.
Years Later, My Career Took Me Into Animal Health
And that’s where I first heard about blood plasma.
In the 1980s, farmers had a problem: baby piglets were dying in big numbers. Being weaned and taken away from their mothers was so stressful that too many of them just didn’t make it.
So researchers at Iowa State University tried something unusual to save them: they added spray-dried blood plasma to the piglets’ diet.
Almost overnight, the piglets’ health improved dramatically... and their survival rate skyrocketed.
Later in my career, I saw that same plasma being used with performance racehorses to help them recover faster and hold up through hard work.
So What Makes Blood Plasma So Powerful?
Plasma is a natural part of blood. Its whole job is to carry nutrients, proteins, and antibodies to the parts of the body that need them most.
Here’s The Problem...
Plasma had been used throughout animal health for decades. But if you were an everyday dog owner, there was almost no practical way to give it to your dog.
I thought that was a huge missed opportunity. So in 2016, I decided to do something about it.
That’s when WINPRO was born.

One Simple Daily Chew That Gives Your Dog The Power Of Plasma.
That’s WINPRO Hip & Joint.
Made with the same plasma that supported those piglets and racehorses... plus type II collagen to support cartilage and connective tissue.
Because there’s one culprit behind an aging dog’s slowdown that almost no other joint product addresses.
Inflammation Is What Your Aging Dog Feels Day After Day.
Inflammation isn’t bad on its own. If your dog cuts a paw and it swells up, that’s the body doing its job.
The problem is inflammation that doesn’t know when to shut off. Low-grade, month after month, year after year, settling into the hips, the knees, the shoulders.
And as dogs get older, it builds. You see it when he takes longer to get up. You see it in the pause at the bottom of the stairs.
Age is the part you can’t change. Inflammation is the part you can.
That’s what plasma is for.
What Should You Expect From Consistent Use Of WINPRO?
Plasma goes to work. Most dogs take the soft chews right away, even picky ones.
Many owners notice less stiffness getting up and more willingness to move.
More energy on walks, and less hesitation at the stairs.
Consistent daily use helps maintain long-term joint health and mobility.
Results and timelines vary by dog. Around the 6-week mark is where a 2026 study in the Journal of Animal Science saw senior dogs with arthritis scoring better on vet lameness scales. That study fed the same type of spray-dried plasma used in WINPRO. It tested the plasma ingredient, not the finished WINPRO Hip & Joint chew.
Here’s What WINPRO Dog Owners Are Saying:
Our Belief:
If we can’t prove it, we don’t put it in a soft chew.
A lot of ingredients end up in dog supplements because they got popular in human supplements first. That’s not how we work.
We’ve spent ten years on plasma because the research was real, the results were real, and dogs kept proving it.
Every WINPRO soft chew is made in the USA and carries the NASC Quality Seal, which means an independent group audits what goes in the product and what we’re allowed to say about it.
And ten years in, we’re still an Iowa company with the same standard we started with.
