Murphy on the Mend

"Murphy used to look like he was wearing brownish red stockings on all four legs. After using the protocol for less than a month, his legs have lighten up. He still has the dark brown grease like areas on his underneath stomach/chest in front of his legs. The areas are getting smaller. I’ve also noticed the bumps which seem to be sites of his scratching are fewer. Also no more Frito smell! After years of vet visits, anti itching shots, trying all kinds of products and diets, this protocol seems to have helped him lot!"

Premium Ingredients

Digest
Digest

Digestive enzymes play a crucial role in breaking down yeast biofilm, a protective layer that yeast cells create to shield themselves from the immune system and yeast treatments. Enzymes such as protease and cellulase, can degrade the components of biofilm, exposing yeast cells to the immune system and making them more susceptible to the ingredients in Yeast Guard. Digestive enzymes also ensure that undigested food particles, which can feed harmful bacteria and yeast, are minimized, thereby supporting the growth of beneficial gut flora. This dual action of breaking down biofilms and promoting nutrient absorption helps in maintaining a healthy gut environment in dogs with yeast issues.

Yeast Guard
Yeast Guard

Yeast Guard is specifically designed to help dogs with yeast and gut issues with a veterinarian formulated blend of organic herbs. Yeast Guard includes potent ingredients such as pau d'arco, oregano leaf, and olive leaf, which are known for their ability to naturally detoxify from yeast overgrowth. It also contains caprylic acid, a medium-chain fatty acid derived from coconut oil, to help break down yeast cell walls, further helping to manage yeast populations in the gut. Yeast Guard supports a healthy gut microbiome, alleviating symptoms associated with yeasty skin.

Gut Guard
Gut Guard

Gut Guard is veterinarian-formulated to address dogs with yeast and gut issues by providing a comprehensive blend of prebiotics, probiotics, and gut-friendly ingredients. It contains a carefully selected mix of probiotics to help maintain a healthy balance of beneficial bacteria in the dog's gut, which is essential for managing yeast overgrowth and promoting a healthy digestive system. Gut Guard also features ingredients like L-glutamine, N-acetyl glucosamine, and DGL licorice root, which are known for their abilities to support a healthy gut lining.

Frequently Asked Questions

What is Yeast Guard Plus?
What is Yeast Guard Plus?

Yeast Guard Plus is a 3-step protocol designed to support a balanced internal environment. It includes Digest, Gut Guard, and Yeast Guard, each targeting a different stage of the yeast cycle: biofilm breakdown, gut-lining support, and yeast balance.

What does yeast buildup commonly look like in dogs?
What does yeast buildup commonly look like in dogs?

While every dog may show different signs, many pet parents notice things such as:

  • A musty or “corn chip” odor
  • Reddish or rusty staining around the paws
  • Excessive paw licking
  • Greasy or discolored coat patches
  • Flaky buildup in skin folds
  • Ear odor or waxy debris

These are not diagnoses — just common signs pet parents observe before choosing a yeast protocol.

Which dogs are good candidates for the full Yeast Guard Plus protocol?
Which dogs are good candidates for the full Yeast Guard Plus protocol?

  • Have both skin and gut concerns
  • Have been on antibiotics or steroids
  • Eat primarily processed diets
  • Need a deeper, multi-layered internal reset
When is the regular Yeast Guard (single product) enough?
When is the regular Yeast Guard (single product) enough?

Yeast Guard alone is typically enough for dogs who:

  • Have mild or occasional yeast flare-ups
  • Already have balanced digestion
  • Need short-term or seasonal support
  • Are using it as part of a simple wellness protocol
How does the Digest step support yeast balance?
How does the Digest step support yeast balance?

Digest helps break down yeast biofilm — the protective layer yeast can form in the gut. By loosening this layer, it allows the rest of the protocol to work more effectively.

What does Gut Guard do during the protocol?
What does Gut Guard do during the protocol?

Gut Guard contains soothing herbs, fermented botanicals, and postbiotics that help support the integrity of the gut lining. A healthy gut barrier is key for long-term microbial balance.

How does Yeast Guard support normal yeast levels?
How does Yeast Guard support normal yeast levels?

Yeast Guard uses organic herbs and C8/C10 MCTs to create an internal environment less favorable to excess yeast. It helps support natural detox pathways and microbial harmony.

Why is a 3-step system better than using one product alone?
Why is a 3-step system better than using one product alone?

Because yeast issues often have multiple layers.

The Yeast Guard Plus protocol works in sequence:

  1. Breaks down biofilm (Digest)
  2. Supports the gut lining (Gut Guard)
  3. Helps maintain normal yeast balance (Yeast Guard)

This layered approach provides more comprehensive support.

How do I give Yeast Guard Plus?
How do I give Yeast Guard Plus?
  • Give Digest 20 minutes before meals.
  • Give Gut Guard and Yeast Guard with meals.

    Most pet parents use the protocol for 30–60 days, depending on the dog.

What should I do after the yeast seems under control?
What should I do after the yeast seems under control?

For long-term maintenance, many pet parents switch to Protect, a daily soil-based probiotic and detox blend that helps support ongoing microbiome health and internal balance.

How soon should I expect to see results?
How soon should I expect to see results?

Every dog responds differently, but many pet parents report improvements in comfort, odor, paw licking, and coat appearance within a few weeks of consistent use.

Is Yeast Guard Plus veterinarian-formulated?
Is Yeast Guard Plus veterinarian-formulated?

Yes. All three products in the kit were developed with veterinarians experienced in gut, microbiome, and yeast-support protocols.

Are there any fillers, synthetics, or artificial additives?
Are there any fillers, synthetics, or artificial additives?

No. The products in Yeast Guard Plus use whole-food ingredients, organic herbs, and clean carriers — never artificial flavors, colors, preservatives, or synthetic fillers.

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.
