Ingredient Benefits
Bacillus subtilis: Bacillus subtilis is a probiotic bacteria found in soil and the canine gut, making it one of the best probiotics for dogs needing better gut and immune health. 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 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 promotes the body’s gut and immune health.

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.
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: 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 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.
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.
Humic acid: 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 helps detoxify from heavy metals and environmental toxins. It also supplies antioxidants and supports the immune system.
Fulvic acid: Like humic acid, fulvic acid is a part of the organic matter in soil, peat and water. Fulvic acid helps detoxify from heavy metals and environmental toxins, supports healthy skin and provides antioxidants.
Organic dandelion root: Dandelion root is renowned for its liver-supporting and detoxifying properties, aiding in the removal of toxins and promoting liver health. It also acts as a natural diuretic, helping to manage fluid retention and support kidney function. Rich in antioxidants, dandelion root can further contribute to a normal inflammatory response.
Organic burdock root: Burdock root supports healthy skin and is also rich in antioxidants, which neutralize harmful free radicals. Burdock root also supports liver function and digestion, thanks to its inulin content, a type of soluble fiber that supports healthy gut bacteria.

F A Q
Why are soil-based probiotics the smarter choice for dogs?
Because they actually survive the trip through your dog’s stomach! These hardy, spore-forming probiotics stay alive and active until they reach the gut no refrigeration needed.
What makes Saccharomyces boulardii so special?
It’s a beneficial yeast that helps keep your dog’s gut environment balanced. Unlike many probiotics, it isn’t affected by antibiotics and works naturally with your dog’s own good bacteria.
How does Protect support natural detox and cleansing?
Protect includes chlorella, herbs and soil-based probiotics ingredients known to bind unwanted materials and support the body’s normal detox process every day.
Can I give Protect daily for ongoing gut support?
Yes! Protect is gentle enough for everyday use and helps maintain a balanced microbiome especially helpful for dogs exposed to lawns, parks, or city environments.
How does Protect help after antibiotics or vaccines?
It’s an ideal “recovery” supplement designed to help restore healthy gut balance and support your dog’s normal immune defenses after life’s occasional stressors.
Does Protect support healthy digestion and stool quality?
Yes. Its blend of soil-based probiotics and beneficial yeast helps promote normal digestion, consistent stools, and comfortable tummies.
When will I notice results?
Most pet parents notice positive changes in stool quality or overall comfort within 1–2 weeks of daily use. Every dog is unique, but consistency pays off!
Can I combine Protect with other Four Leaf Rover products?
Definitely. It pairs perfectly with Gut Guard or Bovine Colostrum for extra digestive and immune system support.
Is Protect safe for puppies or senior dogs?
Yes, it’s safe and beneficial for all ages. Start with a smaller amount for young or small dogs and build up to the recommended dose.
Does Protect need to be kept in the fridge?
Nope! The soil-based probiotics are shelf-stable, so you can keep Protect in your pantry or take it on the go with no loss of potency.
How is Protect different from regular probiotics?
Regular probiotics are fragile and often don’t survive stomach acid. Protect’s spore-forming strains are built to last delivering active support right where it’s needed.
Are there any fillers or artificial ingredients?
Never. Protect is made with clean, whole-food ingredients no soy, dairy, gluten, or artificial additives, just pure quality you can trust.

Good price on 4 Leaf Rover Protect probiotic which has helped my pup tremendously. Shipping was also very quick.
Robert G. (verified owner) –
Every month for a week or two my pup had loose stool. After 3 days of using 4 Leaf Rover Protect, my pup’s stool went from yellow, loose, & watery to firm and dark. Ultimately, he was diagnosed with EPI and I continue to give Protect & it has helped keep his stool mostly firm. Delivery of product was very quick, I will certainly reorder in the future.

Love the ingredients. Love that it’s soil based. Love that it’s not a pill, treat or capsule I have to hide. This is sprinkled on their breakfast with no issues getting them to eat it. Also customer service and shipping are stellar!
Melissa Oddo (verified owner) –
He’s only been on this for a few days now so I can’t really tell, but I will say the customer service is amazing and my product came extremely quick, and somebody even took the time to write woof woof with happy faces in permanent marker!! Just that little tiny personalized writing on my receipt made me extremely happy! Like they actually care about you and your pet! ?? I will see my dog doesn’t quite like the taste of it and I have to mix it with other things for him to take his dose, but with all the reviews from everybody I’m really excited to see the changes to come. I’m definitely ordering more from you guys I love the customer service keep it up ??
Dilwantie R. (verified owner) –
Probiotics are a must for every meal but one pet needs to take antibiotics 2x per day and I was advised that probiotics -especially this plant based one -very pure – was necessary to offset the harshness of the antibiotics which affects his liver. No side effects whatsoever. and will continue to give my 2 other senior dogs as well to keep them healthy. Your packaging is very neat- the products are received very quickly- thank you.
Tamara Pavlock EdD (verified owner) –
It should come with some kind of measuring cup inside.
Mooshiepets Team –
Hello Ms. Pavlock,
You bring up a very good point!
According to Four Leaf Rover, this is something they looked into several times but have not been able to source a measuring scoop/spoon that is made with 100% recyclable material. Since they will not move forward with anything that will have a negative impact on the environment, they have decided not to provide scoops to encourage customers to utilize reusable measuring spoons.
We hope you will understand.
We appreciate your review. Thank you!

Since my dog would eat dirt, I looked up why? Became clear she was searching for something missing from her diet. So protect has the prebiotics and probiotics, and it is just like eating dirt. My 11 year old maltese yeast issues finally seem to be getting better. I dont like chemicals so this has seemed to go to the root of her problem and resolving it organically. It is all natural ingredients so I am thrilled. I have already reccommended it to friends.

My dog has been struggling with GI issues, red eyes and REALLY inflamed and itchy feet. After trying a few different pre/probiotic brands, adding pumpkin and trying different “sensitive skin and stomach” dog food formulas, the next step was to do Rx feeding trials, allergy testing, and GI specific blood work… after some research on gut flora and how it affects the immune system, I came across this product as a final effort before pursuing more vet work (which the vet ok-ed).
This stuff is the holy grail! His poop (after less than a week) is the firmest it’s ever been in the 1.5 years I’ve had him. No more awful gas. No more red, itchy feet. He now LOVES to eat when he would occasionally go 24-48 hours without eating before regardless of what I tried. His poop is more firm than my other dog that doesn’t have the gi issues (though now I think I’ll add some to her food too!). I’m slowly (as a precaution) weaning off the pumpkin, optimistic he won’t even require that any more. Going to put through another order already just to make sure I will always have some on hand. ??
