Product Ingredients

Soil-Based Probiotics - SBOs are species of bacteria found in soil. Unlike Lactobacillus and Bifidobacterium, 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. The SBO's protective coating means they don't need to be refrigerated. 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. The SBOs in PROTECT have been widely used and researched and found to be effective.
Bacillus Coagulans - A friendly little SBO often found in fermented foods, such as sauerkraut. It's well-studied and has a marked effect on inflammatory digestive conditions. Research shows it can help Solve IBS and digestive issues, Balance gut bacteria, Improve immune function, Stimulate the production of anti-inflammatory cytokines, Stop the spread of cancer cells.
Bacillus Subtilis - An SBO inhabitant in healthy guts. Even before antibiotics were developed, B. subtilis was used to treat urinary tract infections and GI diseases. B. subtilis helps the immune system produce immunoglobulin A (IgA). This antibody is often low in dogs with autoimmune disease. It also bolsters the gut lining, which prevents toxins, bacteria, and undigested food from entering the bloodstream and triggering an immune response. B. subtilis also ferments vitamin K and produces 12 strong, natural antibiotics that fight harmful bacteria. It's a powerhouse probiotic with a proven track record!
Saccharomyces boulardii - Considered to be a probiotic but it's actually yeast. But don't confuse it with brewer's yeast! This probiotic yeast is resistant to antibiotics and pesticides. Supports healthy digestion and gastric distress. This little guy loves to attach to heavy metals and eat them. Dogs are constantly exposed to pesticides, vaccines, and harmful heavy metals found in food. It is a healthy way to remove toxins before they travel to the organs and harm your dog. It is also used to treat and prevent diarrhoea, including infectious diarrhoea, such as parvovirus, and the overgrowth of harmful bacteria in the gut. This friendly yeast has also been shown to effectively fight yeast overgrowth and Candida.
Certified Organic Wild Blueberry Powder - Made from blueberries, the most nutrient-dense berries. Plus, they're one of the richest sources of special antioxidants than highbush blueberries called polyphenols. Blueberries can also maintain brain function and improve memory, thanks to their antioxidant activity. In fact, a six-year study showed blueberries delayed mental aging in humans by up to 2.5 years. Wild Blueberries can help maintain a healthy gut flora, support healthy brain function and help decrease oxidative damage.
Bentonite Clay - Comes from volcanic ash. It has a unique structure that can absorb negatively charged toxins, including pesticides, lead, mercury, and other heavy metals. Over time, toxins can build up in your dog's body and interfere with organ function. Bentonite clay has been found to bind to these toxins and help cleanse the body. It can also fight harmful bacteria and encourage the growth of friendly bacteria. This also helps your dog's gut absorb more nutrients.
Chlorella - A species of single-celled green algae. It's extremely nutritious and offers health-boosting properties; Helps detox by removing heavy metals and other toxins from the body and brain, Helps the immune system produce more antibodies, which fight foreign invaders in the body, Rich in antioxidants.
Humic Acid - Comes from the earth just like Fulvic Acid and SBOs. It's also rich in minerals and trace minerals. Because it's getting harder to get enough minerals from food, adding them to the diet is part of a solid health plan for every dog. Humic acid also helps protect cells from viruses and removes pesticides from the body.
Fulvic Acid - Released into the soil as organic matter decomposes. The resulting substance supports your dog's body in many ways; Rich in minerals (which is important because most dogs are deficient in minerals), Helps the body absorb nutrients from food, Naturally high in antioxidants and electrolytes, Can balance the microbiome and restore gut health, A natural source of pre and probiotics, Reacts with free radicals, heavy metals, and toxins and helps eliminate them from the body.
Organic Dandelion - Another antioxidant powerhouse. But it's also rich in prebiotics. Prebiotics are compounds that are fermented by probiotics. They basically feed the healthy (probiotic) bacteria populations in your dog's gut.
Burdock Root - Rich in healthy prebiotics. It's rich in fibre, including inulin and FOS. They inhibit the growth of harmful bacteria in the gut and improve immune function. Burdock root can also lower blood sugar.

Product FAQ

Q : Can I give my dog Protect daily?

A : 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.

Q : Can I give my puppy Protect?

A : 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.

Q : Why does Protect contain fewer bacteria than other probiotics?

A : 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.

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

A : 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.

Q : Will Protect help my dog’s digestive upset?

A : 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.

Q : How do I know if my dog needs probiotics?

A : 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

Q : What is Saccharomyces boulardii?

A : 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.

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

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

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

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

Q : Should I keep Protect in the fridge?

A : 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.
