Protect is our best-selling everyday probiotic. Rich in antioxidants, this soil-based probiotic helps support the immune system and gut, and helps the body remove and detoxify toxins.

PROTECT is a daily supplement with ingredients that can target your dog's immune system and brain including:

Soil-based Probiotics

Soil-based probiotics are hardy species that are much better at surviving changes in pH and temperature than traditional probiotics. This makes them more likely to colonize and deliver health benefits. 

Saccharomyces boulardii

A healthy, probiotic yeast used to support a healthy gut and fight yeast and Candida.

Certified Organic Wild Blueberry Powder

Helps maintain brain function and fight oxidative stress.

Bentonite Clay, Chlorella, Humic & Fulvic Acid

Help remove toxins and dangerous heavy metals from the body.

Organic Dandelion & Burdock Root

A healthy supply of natural, whole-food prebiotics.

Protect is a daily supplement for both healthy dogs and dogs with digestive or immune issues. This veterinary formulated probiotic is ideal for everyday use.

Soil-based probiotics (SBOs) are species of bacteria found in soil. Unlike  Lactobacillus and Bifidobacterium species, most SBOs are spore-forming. This means they can form a hard coating that protects them from heat, stomach acids and most antibiotics. In fact, many antibiotics are made from SBOs. And unlike most probiotics that come from dairy (like Lactobacillus and Bifidobacterium), the SBOs in Protect are hypoallergenic. That's good news for dogs with dairy allergies.

    Can I give Protect every day?

    Yes, Protect is a daily probiotic to support healthy guts. Protect has whole food prebiotics and healthy soils to help safely work towards the removal of toxic heavy metals from your dog. 

    If you’re giving probiotics as part of a preventative health plan, you can give Protect daily. Soil-based probiotics, like Protect, are typically a better choice for everyday probiotics since they are less likely to cause small intestinal bacterial overgrowth (SIBO). 

    How should I store Protect?

    We recommend you keep Protect in the fridge. If not, make sure you keep it in a cool, dark place.

    Can I give my dog Protect if he’s on antibiotics? 

    We’d suggest choosing Protect as a probiotic if your dog is on antibiotics. A 2018 study* found that the best probiotics to help restore your dog’s microbiome after antibiotics are Saccharomyces boulardii and soil-based probiotics (Bacillus subtiliis and Bacillus coagulans). The study also found that Lactobacillus probiotics after antibiotic use caused a delay in the microbiome’s recovery when compared to the group given no probiotics.

    *Suez J et al. Post-antibiotic gut mucosal microbiome reconstitution is impaired by probiotics and improved by autologous FMT. Cell. 2018 Sep 6;174(6):1406-1423.e16.

     Can I give Protect to my puppy?

    Probiotics can be useful for puppies in some cases. If your puppy was eating kibble and is being switched to raw or fresh food, then probiotics can help prevent or manage potential digestive upset. But most healthy puppies need a simple approach and it's best to focus on whole foods and solid nutrition for the best start possible.

    Why is there chlorella in Protect? 

    One of chlorella’s biggest advantages is that it’s a natural detoxifier ... that’s why we’ve included it in Protect’s formulation. It’s known to bind to and remove toxins from the body. This includes heavy metals. Heavy metals are commonly found in …

    • Pesticides and herbicides 
    • Vaccinations
    • Processed pet food
    • Flea, tick and heartworm preventatives
    • Pollution 

    Why does Protect contain fewer bacteria than other probiotics? 

    Most probiotic strains like Lactobacillus and Bifidobacterium are very fragile and most don't survive the trip through the stomach ... the ones that survive only last about 24 hours before they’re eliminated from the gut.

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

    How does Protect help reduce toxins in my dog? 

    Protect was formulated with chlorella, bentonite clay and humic and fulvic acids which can all bind to toxins and heavy metals to help exit them from the body. 

    • Humic and fulvic acids provide excellent detoxification support for the body and help to neutralize toxins.  
    • Bentonite clay’s absorption rate can be up to 8x higher than other clays. 
    • Chlorella can bind to and remove toxins including heavy metals from your dog’s body. 

    I think my dog has leaky gut. Should I give him Protect? 

    If you suspect your dog has leaky gut, we would recommend Gut Guard. Gut Guard is a veterinary-formulated blend of gut soothing ingredients that can help seal leaky guts and reduce gut inflammation. 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. Gut Guard also contains organic herbs and foods that help control inflammation in the digestive tract, plus natural prebiotics to help restore healthy bacteria colonies. 

      I think my dog has Yeast. Should I give him Protect? 

      If your dog is dealing with ear infections, itchy skin and paws, or hair loss, it could be yeast, not allergies. We have created a product trio specifically to target yeast! Check out Yeast Guard Plus.

      There are three important steps to help squash Candida, which include these three powerful products: Yeast Guard, Digest & Gut Guard.

      My dog has diarrhea. Will Protect help? 

      Yes, Protect can help with diarrhea. Studies show that probiotics can cut the recovery time roughly in half. It’s best to continue the probiotics for a few weeks, to try and help resolve the underlying gut issues. 

      If your dog has chronic diarrhea or a digestive disorder, a good multi-strain probiotic with gut-soothing herbs is a better choice. If Protect isn’t able to help with your dog’s diarrhea, take advantage of our 30 day money back guarantee and try Bifido For Fido instead. This multi-strain, high CFU probiotic blend can help restore normal gut and bowel function. 

      Can I give my dog Protect if my dog has SIBO? 

      If you suspect your dog has small intestinal bacterial overgrowth (SIBO), Spore-forming (soil-based) bacteria, like those found in Protect, are a good choice. These probiotics have a protective coating that allows them to stay in their spore state until their environment is safe. This allows them to pass through the small intestine and colonize in the colon, where they belong. 

      Does my dog need probiotics? 

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

      • Digest food
      • Produce key vitamins (including vitamin K and B vitamins)
      • 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

      Since 80% of the immune system is in the gut, most, if not all dogs can benefit from probiotics and prebiotics. 

      What is Saccharomyces boulardii?

      Saccharomyces boulardii is a healthy yeast and not a bacterium. But it’s still considered a probiotic because it delivers benefits to the gut and immune system. S. boulardii also helps with digestive issues caused by chronic inflammation … and can alter cell signaling pathways in the immune system.

      Saccharomyces boulardii is used to treat acute and chronic diarrhea in humans … and a recent trial in dogs showed the same benefits. S. boulardii has also been successfully used to treat Candida and yeast. This probiotic is unique in that it can’t be killed by antibiotics … so it can be taken at the same time as antibiotic use to help protect the beneficial gut bacteria. 

      So this friendly little yeast is a great consideration for most dogs … it’s a good addition to your dog’s probiotic.

        Great stool consistency, less regurgitation

        I was unaware that Bifido for Fido was a probiotic that was to be used for occasions like giving antibiotics, stress, anxiety, bouts of upset stomach so was informed by your customer service to use the Protect as an everyday probiotic. It's worked well! My dogs have great poop and less regurgitation. They are fed a raw diet and we just mix it in with their food and they eat it right up, no problem! We use 4 of your products faithfully and we love them! Our dogs have better health because of your company!

        Dirt don't hurt!

        I'm really big believer in taking our cues on what our pets needs from their own behaviors and habits. I have a dog that has IBD and we have tried dozens of probiotics over the years. She has always had a habit of eating dirt and I finally have found a soil based probiotic that satisfies her biological need. She dirt eats has lessened and her BMs (we also use the Red Rover supplement) are the best they have ever been. It did take her about a week adjust to the new supplement hence the 4 stars (if your pup has a sensitive system I'd introduce slowly) otherwise we are very happy!

        Helpful to improve his business

        My 8mo GSD had trouble with runny poops while eating a mostly raw diet with kibble as training treats. We ditched the kibble and added these probiotics and he’s no longer straining or squatting more than once to get the job done. It’s only been a few weeks, so I’m hoping his turds firm up even more in the coming months with the help of these probiotics.

        Good for Guts and Eyes!

        this stuff gets rid of eye goop in my younger dog. i also think it helps keep both my dogs’ guts healthy. i gave my daughter some for her puppy who had to take antibiotics for too long. i recommend Four Leaf Rover to every dog owner that comments on my older dog’s good health all the time!!

        Healing from the trauma of dog poop fixation!

        Thank you so much for creating this product!!! My little 12 year old mini doxie has colitis and he's tried everything, EVERYTHING people (for real, ok he didn't do the Medical Medium protocol but like everything else so don't go second guessing what else I could have tried! LOL!)! So we are talking months of accidents in the house, in the bed, on the couch, on me, on my husband. The vet unfortunately was useless. Poor little guy. It really upset him more than it did me. So needless to say I was so grateful to find this company! He is doing a combination of Protect and gut guard so I honestly don't know if it was the combo, potentially. But, I'm not going to go without this for the rest of his (all too short because he's a dog) life! I beam with pride (and report with triumph to my husband) when I scoop little "cigars" in the yard, now (the little things you know... and fortunately they are little). Our home became a place of dog poop fixation for a while, no more! We can all move on with our lives thankfully due to Four Leaf Rover!
