What handlers are saying

Flyball Team

“Vertex has become a staple in our training routine”

As a competitive flyball team, we know that peak performance requires not just skill and teamwork, but also the strength and stamina to handle the high-speed demands of the sport. That's why we turned to Vertex.

World Qualifier, 2014

“I have to admit that I was amazed”

I've always been a skeptic when it comes to supplements for dogs. When Greg began to have stamina issues due to a health concern during the World Qualifier in 2014 I decided to look into CPN's Vertex and Power Boost.

IPO Competitor

“The difference on energy level is very noticeable”

As I'm starting to prep Caribou for his 6th and last trial season, we couldn't do it without the best supplement out there, so I ordered some Vertex, to help recover and build his muscles, and keep his weight, energy and stamina up.

— Mario Sore, national and world level IPO competitor

Why Vertex supports the whole dog, not just the joints

Joint health isn’t an isolated fix — it depends on what’s fueling the rest of the body. Here’s why we built Vertex around whole-food protein first.

Joint fluid and cartilage are largely built from protein — so real joint support starts with giving your dog's whole body the raw materials to build and repair, not just an isolated joint ingredient. That's why Vertex is formulated around high-quality, whole-food protein sources first, with glucosamine and chondroitin working alongside them, not standing alone.

It's also why dogs on Vertex tend to see more than joint comfort — better muscle recovery, coat condition, and stamina tend to follow when the underlying protein foundation is right.
