Bacillus subtilis
Bacillus subtilis is a probiotic bacteria found in soil and the canine gut, making it one of the best probiotics for dogs to support gut and immune health. B. subtilis is known for its ability to support a healthy gut microbiome, enhance digestive health and support immune function. 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 is a soil-based probiotic that supports gut health and the immune system by supporting the balance of the intestinal flora.

Saccharomyces boulardii is a probiotic yeast that has been shown to support gut health, especially during antibiotic use and travel. It helps maintain the natural flora in the gastrointestinal tract, supporting immune function.
Wild Blueberries contain more antioxidants than other berries and are very rich in a specific antioxidant called anthocyanins, which support a healthy heart and brain. Blueberries also help maintain a healthy gut flora. Four Leaf Rover chooses organic blueberries to minimise exposure to synthetic pesticides and fertilisers, providing a safer and healthier option for your dog.
Bentonite clay is a natural detoxifier that helps to detoxification of environmental toxins, supporting a healthy microbiome.
Chlorella pyrenoidosa, a species of freshwater algae, is highly regarded for being a rich source of antioxidants. It supports immune function, detoxification and gut health due to its high fibre content.
Humic acid is a natural component of soil and a byproduct of the decomposition of leaves and other plant material by soil-based microorganisms. Humic acid supports a healthy gut and supplies antioxidants and supports the immune system.
Like humic acid, fulvic acid is a part of the organic matter in soil, peat and water. Fulvic acid helps detoxification, supports healthy skin, and provides antioxidants.
Dandelion root is rich in antioxidants and is renowned for its liver-supporting and detoxifying properties, as well as supporting healthy kidney function.
Burdock root supports healthy skin and is also rich in antioxidants. Burdock root also supports liver function and digestion, thanks to its inulin content, a type of soluble fibre that supports healthy gut bacteria.

Yes! Protect is a veterinarian-formulated soil-based probiotic blend made for daily use.
Four Leaf Rover made Protect to support a healthy gut and immune system, while helping your dog detoxify from everyday pesticide and toxins. Protect is a great choice as a daily preventive plan for good health.
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.
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 colonise in the colon where they belong, not in the small intestine.
Yes, Protect contains probiotics that have a proven track record in supporting gut and digestive health.
Since 80% of the immune system lives in the gut, most dogs can potentially benefit from probiotics.
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
Saccharomyces boulardii is considered a probiotic because it supports 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.
Protect has little white specks, which are the probiotics and prebiotics.
You can expect a natural variation in colour in Protect due to the bentonite clay and other earthy ingredients. It’s perfectly normal.
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 it in a cool, dark place and use the jar within 30 days of opening.
