  • Next-generation probiotics: Soil-based probiotics are hardier than typical probiotics and less likely to be damaged by stomach acids.
  • Rich in antioxidants: Contains organic blueberries to help maintain a healthy gut flora, support healthy brain function and help decrease oxidative damage.
  • Veterinarian formulated: Formulated by a holistic veterinarian for maximum safety and benefit.

Premium Ingredients

Bacillus subtilis
Bacillus subtilis

Bacillus subtilis is a probiotic bacteria found in soil and the canine gut. B. subtilis is known for its ability to support a healthy gut microbiome, enhance digestive health and support immune function. It produces byproducts that can help suppress harmful bacteria, promote the growth of beneficial bacteria and assist with nutrient absorption. Additionally, Bacillus subtilis has been associated with digestive enzyme production, aiding in the digestion of food and the supporting against gastrointestinal disorders.

Soil-based probiotics, like Bacillus subtilis, are often considered superior to other probiotics due to their exceptional resilience and ability to survive the acidic environment of the stomach, ensuring they reach the intestines where they can be most beneficial. Their inherent stability means they don't require refrigeration and maintain potency over time and their robust nature allows for a potentially broader impact on the gut microbiome.

Bacillus coagulans
Bacillus coagulans

Bacillus coagulans is a soil-based probiotic that supports gut health by enhancing the balance of the intestinal microbiota, contributing to improved digestion and reducing symptoms of occasional bloating, gas, and diarrhea. It also supports the immune system by producing short-chain fatty acids, which are crucial for gut health and the natural resistance against chronic diseases.

Saccharomyces boulardii
Saccharomyces boulardii

Saccharomyces boulardii is a probiotic yeast that has been shown to support gut health, especially during antibiotic use, travel and infections. It helps maintain the natural flora in the gastrointestinal tract, enhancing immune function and a balanced inflammatory response in the gut.

Organic blueberries
Organic blueberries

Wild Blueberries contain more antioxidants than other berries and are very rich in a specific antioxidant called anthocyanins, which support a health heart and brain. Blueberries also help maintain a healthy gut flora and help decrease oxidative damage. We choose organic blueberries to minimize exposure to synthetic pesticides and fertilizers, providing a safer and healthier option for your dog.

Bentonite clay
Bentonite clay

Bentonite clay is a natural detoxifier that helps the body remove toxins and heavy metals from the body. It is known to bind to toxins and metals in the gut, supporting a healthy microbiome.

Chlorella pyrenoidosa
Chlorella pyrenoidosa

Chlorella pyrenoidosa, a species of freshwater algae, is highly regarded for being a rich source of antioxidants. It supports immune function, aids in detoxification by binding to heavy metals and other toxins for elimination from the body, and supports gut health due to its high fiber content. Additionally, its antioxidant properties may help reduce oxidative stress.

Frequently Asked Questions

Can I give my dog Protect daily?

Yes! Protect is a veterinarian formulated soil-based probiotic blend made for daily use.

We made Protect to support a healthy gut and immune system, while helping your dog detoxify from everyday pesticide and toxin exposure. Protect is a great choice as a daily preventive plan for good health. 

Can I give my puppy Protect?

In most cases, if you have a new puppy, it’s best to focus on fresh whole food nutrition for a good start to life. But in some cases, probiotics can be helpful. If your puppy is changing from a processed diet, then a probiotic can help support good digestion. 

Why does Protect contain fewer bacteria than other probiotics? 

Soil-based probiotics are spore-forming, which means they can form a hard coating that protects them from the high heat and stomach acids that typically damage most probiotics. It also helps them colonize in the colon where they belong, not in the small intestine. 

I think my dog has leaky gut, should I give him Protect? 

We recommend Gut Guard if you wish to support a normal gut lining. Gut Guard is a veterinarian formulated blend of gut friendly ingredients that can help support a normal inflammatory response. Gut Guard also contains spore-forming probiotics, which form a protective shell when stressed and are more likely to survive and colonize than other species. Protect is certainly gut friendly, but Gut Guard will offer more support for the gut lining. 

Will Protect help my dog’s digestive upset? 

Yes, Protect contains probiotics that have a proven track record in supporting gut and digestive health. If you don’t have success with Protect, try Bifido For Fido instead. (Take advantage of our 30 day money back guarantee). While Protect is a daily probiotic, BFF is a multi-strain probiotic for occasional digestive upset.  

How do I know if my dog needs probiotics?

Since 80% of the immune system lives in the gut, most dogs can benefit from probiotics. 

Probiotics are live organisms that provide health benefits. These beneficial bacteria have a few key jobs in your dog’s body. Gut bacteria can help:

  • Digest food
  • Produce key vitamins (including Vitamin K and Vitamin B)
  • Produce serotonin and influence mood
  • Produce enzymes
  • Reduce the gut pH
  • Crowd out harmful bacteria
  • Produce fatty acids that discourage the growth of harmful bacteria
  • Support the immune system

What is Saccharomyces boulardii?

Saccharomyces boulardii is considered a probiotic because it benefits the gut and immune system like a probiotic. But it's actually a healthy yeast, not a bacterium.

As a probiotic yeast, S. boulardii is much less susceptible to gut-stressing drugs and chemicals than probiotic bacteria are.

I noticed white specs in the blend, what causes this?

Protect has little white specks, which are the probiotics and prebiotics.

Why is my jar of Protect a different color than the last one?  

You can expect a natural variation in color in Protect due to the bentonite clay and other earthy ingredients. It’s perfectly normal.

Should I keep Protect in the fridge?

If you have room, we recommend keeping Protect in the fridge. While the soil-based probiotics are shelf stable, the Saccharomyces boulardii is more fragile. If you can’t store it in your fridge, just be sure to keep in a cool, dark place and use the jar within 30 days of opening.

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.
