Premium Beef Collagen for Dogs on the Go

Beef collagen is beneficial for joint health due to its rich content of Type I and Type II collagen, which are key components of cartilage, tendons and ligaments. It’s also abundant in amino acids to help maintain normal cartilage repair in the joints.

  • Cartilage Support: Healthy joints are cushioned by cartilage for smooth, pain-free movement. Beef collagen provides collagen peptides and amino acids that are essential for cartilage matrix formation. 
  • Bone Support: Beef collagen supports the bone matrix for stable, robust bones.
  • More Complete: Beef collagen is rich in Type I and Type II collagen and chondroitin, which are the main structural components of cartilage, tendons, ligaments and bones, while marine collagen mainly contains only Type I collagen.
  • Quality & Sustainability: We source from pastured cows for a highly bioavailable collagen that’s clean and sustainable.

Frequently Asked Questions

What makes Four Leaf Rover Collagen different from other collagen supplements?
What makes Four Leaf Rover Collagen different from other collagen supplements?

Our collagen is made from grass-finished New Zealand beef and provides a rich, naturally balanced spectrum of collagen peptides — including Type I and a minimum 40% Type II collagen, plus 20% chondroitin sulfate for unmatched structural support.

Why choose beef collagen instead of marine collagen?
Why choose beef collagen instead of marine collagen?

Beef collagen is more complete. It contains both Type I and Type II collagen, along with natural chondroitin — the key components of cartilage, tendons, ligaments, and bones. Marine collagen is mostly Type I only, making it less comprehensive for joint and connective tissue support.

How do Type II collagen and chondroitin sulfate support my dog’s joints?
How do Type II collagen and chondroitin sulfate support my dog’s joints?

Type II collagen and chondroitin sulfate are the main structural elements of cartilage. Together they help maintain normal joint cushioning, flexibility, and connective tissue integrity.

Why is high bioavailability important in a collagen supplement?
Why is high bioavailability important in a collagen supplement?

Because the more easily collagen is absorbed, the more effectively it can support normal tissue maintenance. Our beef collagen is highly bioavailable, making it easy for your dog’s body to use the peptides for healthy cartilage and bone matrix support.

What do the amino acids glycine, proline, and hydroxyproline do?
What do the amino acids glycine, proline, and hydroxyproline do?

These amino acids are the building blocks of collagen. They help maintain strong connective tissues, promote healthy joint structure, and support overall mobility.

Why does grass-finished New Zealand sourcing matter?
Why does grass-finished New Zealand sourcing matter?

New Zealand’s strict regulations ensure cattle are pasture-raised, grass-finished, and raised without growth hormones or routine antibiotics. This produces exceptionally clean, sustainable, and traceable collagen.

Are there safety concerns with marine collagen?
Are there safety concerns with marine collagen?

Marine collagen can be more prone to heavy metal and environmental contaminant exposure. Our New Zealand beef collagen is tested for purity and quality, offering a safer, cleaner alternative.

Can collagen be used daily?
Can collagen be used daily?

Absolutely. Daily use helps maintain normal cartilage health, tendon and ligament structure, and overall joint comfort.

Is it suitable for senior or active dogs?
Is it suitable for senior or active dogs?

Yes. Collagen peptides support normal mobility, making them beneficial for aging dogs, high-activity dogs, and dogs needing extra connective tissue support.

Does this collagen contain any fillers or artificial ingredients?
Does this collagen contain any fillers or artificial ingredients?

Never. It’s pure, hydrolyzed beef collagen — no flavors, no preservatives, no binders, and no synthetic additives.

Can I combine collagen with other Four Leaf Rover supplements?
Can I combine collagen with other Four Leaf Rover supplements?

Definitely. It pairs especially well with Hip & Joint or Safe-Sea for a broader joint and mobility routine.

Who We Are

In Memory of Simon & Aaron

The story of Four Leaf Rover started as a tragedy. Our founder Dana Scott lost two dogs from toxic sprays they were exposed to in the fields surrounding her home. In a frantic effort to save her dogs and protect her remaining dog family, Dana connected with most of the leading holistic veterinarians around the world about the most effective natural remedies. As Dana researched remedies, she found nearly all contained hidden or harmful ingredients. Four Leaf Rover began as a promise to Dana's lost dogs that all dogs deserve super premium products with natural ingredients that are thoroughly tested to be low in harmful pesticides and heavy metals. With a mission of quality, transparency and sustainability, Four Leaf Rover is making the world a better place for dogs and the people who love them.
