ThorneVet · Probiotic Support FormulA The Probiotic That Actually Gets There. Two spore-forming bacteria that survive stomach acid by forming a protective shell. A probiotic yeast that antibiotics cannot kill. A prebiotic complex that prepares the gut for successful colonization. Plus the gut wall's primary fuel source. ✓ Spore-Forming Bacteria ✓ Antibiotic-Resistant Yeast ✓ OliveGuard Prebiotic ✓ Non-GMO ✓ 60 Scoops/Chews The problem with most dog probiotics Most pet parents are giving their dog a probiotic every day and delivering almost nothing alive to the gut. The research behind why the gut microbiome matters is genuinely compelling. The community of bacteria living in your dog's digestive tract influences immunity, inflammation, digestion, nutrient absorption, skin health, behavior, and long-term organ health. Every holistic-minded pet parent has heard this. Most are already giving their dog a probiotic. But here is what nobody tells you: the stomach is designed to destroy bacteria. It produces powerful acid specifically to kill them, including the pathogens that could cause illness if they reached the intestine alive. That acid does not distinguish between harmful bacteria and the beneficial probiotic bacteria in a supplement. It treats them all the same. Most dog probiotics Use conventional Lactobacillus and Bifidobacterium strains that are fragile organisms. They cannot survive stomach acid. The majority of their bacteria are killed before ever reaching the intestine where the microbiome actually lives. Those enormous label numbers, 50 billion, 100 billion CFUs, exist only to compensate for the massive die-off. It is a losing battle against an environment designed to kill bacteria. Probiotic Support Formula Uses spore-forming bacteria that form a hard protective shell when they hit stomach acid, walk right through it completely intact, and wake up in the intestine to start colonizing. Plus a probiotic yeast that antibiotics cannot kill. Five billion CFUs that are genuinely alive when they arrive. That is what makes the difference. How spore-forming probiotics work Think of it like sending soldiers into battle. Regular probiotics have no armor. Spore-forming probiotics suit up before they go in. Step 1 · In the stomach When the bacteria hit the acid environment of the stomach, they form a hard dormant shell around themselves called a spore. Inside that shell they are essentially indestructible. The acid cannot reach them. Step 2 · In the intestine The bacteria arrive at the intestine alive. Sensing the more hospitable environment, they open the shell and become active again. They start colonizing, doing the actual work that probiotics are supposed to do. The result Organisms that are genuinely alive and active when they reach the gut, not mostly dead from the stomach acid journey. This is why 5 billion CFUs of spore-forming bacteria is more clinically meaningful than 100 billion CFUs of conventional strains that are mostly dead on arrival. The full formula Five ingredients. The most resilient and comprehensive probiotic formula for dogs we carry. Two spore-forming bacteria, one antibiotic-resistant yeast, a prebiotic that prepares the gut for successful colonization, and the primary fuel source for gut wall cells. Every ingredient is here for a specific reason and does a job the others cannot do. OliveGuard · 500mg Extra virgin olive oil complexed with acacia fiber The highest-dosed ingredient · prepares the gut garden before planting OliveGuard does two distinct and important things simultaneously. The olive oil polyphenols act as a prebiotic, selectively feeding beneficial bacteria and making the gut environment favor healthy microbial populations. They also have direct anti-inflammatory properties in the gut lining and support the integrity of the gut wall itself. The acacia fiber component is a soluble prebiotic fiber that provides additional food for beneficial bacteria and specifically supports the production of the compounds that gut lining cells use as their primary fuel. Think of OliveGuard as preparing the garden bed before planting. It creates the ideal conditions for the probiotic organisms to take hold and thrive. L-Glutamine · 200mg Primary fuel for the gut wall cells Maintains the physical gut wall while probiotics restore the microbiome L-Glutamine is the primary fuel source for the cells lining the gut wall. It is the most important nutrient for maintaining the seals between those cells that keep the gut barrier intact, preventing what is often called leaky gut. Roughly 70% of the immune system lives in and around the gut wall, so when that barrier is compromised, immune function is compromised alongside it. In a probiotic formula, L-Glutamine plays a specific supporting role: the probiotics restore the microbial community, and L-Glutamine provides the fuel the gut wall cells need to maintain the physical barrier. One rebuilds the community. The other maintains the infrastructure. Both are necessary for genuine gut health. Bacillus coagulans · 2 Billion CFUs Spore-forming · soil-based · extensively researched Arrives alive · creates conditions beneficial bacteria love One of the most clinically studied probiotic strains available. Once it arrives in the intestine and becomes active, it produces lactic acid that lowers gut pH in a way that beneficial bacteria prefer and harmful bacteria find inhospitable. Think of it as making the environment as welcoming as possible for the rest of the healthy microbial community. Has been shown to improve stool consistency, reduce diarrhea severity, and support healthy gut inflammatory balance. Its spore-forming nature means it is reliably arriving in your dog's gut alive and active. Bacillus subtilis · 2 Billion CFUs Spore-forming · soil-based · natural antimicrobial activity Arrives alive · acts as the gut's natural security force against harmful organisms The second spore-forming organism, contributing a distinct set of activities that complement rather than duplicate Bacillus coagulans. Produces natural antimicrobial compounds that directly inhibit the growth of pathogenic bacteria in the gut, including Salmonella, E. coli, and Clostridium species. Think of it as the gut's own natural security force, selectively targeting harmful organisms without disrupting the beneficial microbiome. Also produces enzymes that enhance the digestion and absorption of nutrients, and helps maintain the diversity and balance of the overall microbial community. Saccharomyces boulardii · 1 Billion CFUs Probiotic yeast · antibiotics cannot touch it The antibiotic situation · the most important ingredient during antibiotic treatment Antibiotics kill bacteria. That is what they do. But they cannot distinguish between harmful bacteria and the beneficial bacteria in the gut microbiome. A course of antibiotics can devastate the microbiome, wiping out beneficial populations that may take months to fully recover. The two bacterial probiotics above are killed right along with everything else during antibiotic treatment. Saccharomyces boulardii is a yeast, not a bacterium. Antibiotics do not affect it at all. It survives antibiotic treatment completely intact, maintaining a probiotic presence in the gut during and immediately after the course when the bacterial microbiome has been most devastated. It also boosts the gut's own protective antibody production, reduces gut permeability that antibiotic disruption causes, and blocks pathogenic organisms from taking hold while the bacterial microbiome is rebuilding. For any dog on or recently off antibiotics, this is the most critical ingredient in the formula. Why three organisms are better than one Bacillus coagulans makes the gut environment hospitable for beneficial bacteria and supports stool consistency and inflammatory balance. Bacillus subtilis acts as the antimicrobial security force, targeting harmful organisms that try to establish themselves when the microbiome is disrupted. Saccharomyces boulardii covers the one situation neither bacterial probiotic can handle: antibiotic treatment. Together they form a three-organism approach that is more resilient and more effective in more situations than any single-strain formula. On the CFU count Five billion CFUs may look modest. It is not. Here is why. Those enormous numbers on other probiotic labels, 50 billion, 100 billion, 200 billion CFUs, exist only to compensate for the massive die-off of fragile conventional strains in the stomach. The goal is not the number on the label. It is the number that actually reaches the gut and does something. Five billion CFUs of spore-forming bacteria that arrive intact and colonize effectively is more clinically meaningful than a hundred billion CFUs of conventional strains that are mostly dead upon arrival. This formula optimizes for the right metric. Not the biggest number. The most viable organisms reaching the right destination. What happens step by step Here is what this formula is doing in your dog's gut every day. 1 The groundwork is laid first OliveGuard's polyphenols create a gut environment that favors beneficial bacteria and reduces gut inflammation. Its acacia fiber provides food for the beneficial organisms about to arrive. L-Glutamine fuels the gut wall cells to maintain the physical barrier. The garden is prepared before the seeds go in. 2 Both spore-forming bacteria pass through stomach acid intact Bacillus coagulans and Bacillus subtilis form their protective shells in the stomach environment, arrive in the intestine alive, and wake up. Bacillus coagulans begins producing lactic acid, making the gut more hospitable for beneficial organisms. Bacillus subtilis begins its antimicrobial work against pathogenic organisms trying to establish themselves. 3 Saccharomyces boulardii covers the gap the bacteria cannot If your dog is on antibiotics, the bacterial probiotics may be affected. Saccharomyces boulardii is not. It maintains probiotic presence throughout the antibiotic course, boosts protective antibody production in the gut, and helps prevent pathogenic organisms from taking hold during the microbiome's most vulnerable period. 4 Over time, a stronger and more resilient microbiome Done consistently every day, this combination builds a more diverse, more resilient, more functional microbiome than existed before. One that is better able to defend itself against disruption, better able to support immune and inflammatory function, and better able to contribute to the whole-body wellness that a genuinely healthy gut makes possible.

Questions and answers Everything you want to know before you buy. Why do most dog probiotics have such high CFU counts? Because conventional Lactobacillus and Bifidobacterium strains cannot survive stomach acid. The vast majority of the bacteria in those products are killed before they ever reach the intestine where the microbiome lives. Manufacturers compensate by using enormous numbers, hoping enough survive to make a meaningful difference. When spore-forming strains are used, this problem is solved at the source. Five billion CFUs of spore-forming bacteria that arrive intact and colonize effectively is more clinically meaningful than a hundred billion CFUs of conventional strains that are mostly dead upon arrival. What probiotic should I give my dog during or after antibiotics? The most important probiotic during antibiotic treatment is one that antibiotics cannot kill. Saccharomyces boulardii, the probiotic yeast in this formula, is completely immune to antibiotics because it is a yeast rather than a bacterium. It maintains probiotic presence throughout the course when the bacterial microbiome is being devastated. The spore-forming bacterial strains then help rebuild the bacterial microbiome as the antibiotic clears the system. Starting probiotic support during antibiotic treatment rather than waiting until after it ends provides significantly better gut protection and faster recovery. What is a soil-based probiotic and why does it matter? Soil-based probiotics are organisms that evolved in the natural soil environment rather than in the mammalian gut. Because of that environment, they developed the ability to form protective shells called spores that allow them to survive harsh conditions including stomach acid, heat, and moisture. This makes them dramatically more stable and reliably viable than conventional probiotic strains. When you give your dog a soil-based spore-forming probiotic, you can be genuinely confident the organisms are arriving in the gut alive and active rather than mostly dead from the stomach acid journey. What is OliveGuard and why is it in a probiotic supplement? OliveGuard is a patented ingredient that combines extra virgin olive oil with acacia fiber. The olive oil polyphenols act as a prebiotic, selectively feeding beneficial bacteria and reducing gut inflammation. The acacia fiber is a soluble prebiotic that supports the production of the compounds that gut lining cells use as their primary fuel. Together, OliveGuard creates the ideal gut environment for the probiotic organisms to colonize and thrive. At 500mg it is the highest-dosed ingredient in the formula, reflecting its foundational role in the overall gut support approach. Without the right environment, even the best probiotic organisms struggle to take hold. Do dogs need a probiotic every day? Yes, and daily use is how probiotics provide the most meaningful benefit. The gut microbiome is a dynamic living ecosystem constantly influenced by diet, stress, medications, and environmental exposure. Consistent daily probiotic support helps maintain a healthy microbial balance rather than allowing populations to fluctuate with each dietary or environmental disruption. Think of daily probiotic supplementation as maintaining the garden rather than only intervening when the weeds have already taken over. What do holistic vets recommend for dog gut health? Holistic and integrative veterinarians consistently recommend probiotic strains that reliably survive stomach acid, which means spore-forming and yeast-based organisms over conventional Lactobacillus strains for dogs. They also consistently recommend pairing probiotics with a prebiotic fiber source to feed the beneficial organisms and support colonization, and with gut wall nutritional support like L-Glutamine to maintain the physical gut barrier alongside the microbial population. The combination of spore-forming bacteria, an antibiotic-resistant probiotic yeast, a prebiotic complex, and gut wall support in this formula reflects exactly that integrated approach. The clean formula standard you expect 3 probiotic organisms Spore-forming strains that survive stomach acid Saccharomyces boulardii unaffected by antibiotics OliveGuard prebiotic complex at 500mg Non-GMO Third-party tested NASC Certified Trusted by integrative veterinarians Your dog's microbiome is the foundation of their health. Give it the probiotic support that actually delivers. The gap between what most probiotic products deliver and what the research actually requires is enormous. The average pet store probiotic with its hundred billion CFUs of Lactobacillus strains is mostly delivering dead bacteria. The impressive number on the label is compensating for a delivery problem that was never solved. This formula solves it. Spore-forming Bacillus coagulans and Bacillus subtilis that are effectively indestructible on their journey through stomach acid · Saccharomyces boulardii that antibiotics cannot eliminate · OliveGuard prebiotic preparing the gut for successful colonization · L-Glutamine maintaining the gut wall the microbiome depends on Five ingredients.
