What Are Probiotics?

Probiotics contain bacteria found naturally in the digestive tract and other body areas. Taking probiotics aims to keep good bacteria healthy. It helps prevent gastrointestinal problems and boost the immune system after being disrupted by illness, infection, antibiotic treatment, or other stressors.


Probiotics have a wide range of health advantages, but some key benefits include:

  • Decreases incidences of diarrhea and flatulence
  • Improves bad breath
  • Helps recovery from illnesses and infections
  • Enhances immune response

It aids in treating numerous disorders, including inflammatory bowel syndrome and kidney disease.

Anti-inflammatory qualities reduce pain and swelling.

  • Enhances stress reaction

You might have a stomach upset when you start a new probiotic regimen. It is common to make any significant change to your diet for people and pets. It might be good to start with a less recommended dose, so your pet’s stomach can get used to the new food.

What To Look For

Because each dog’s health needs vary, look for a probiotic mix with bacterial strains that address your dog’s specific needs, such as intestinal infections, diarrhea, etc. We list the probiotic blends included in each product we review.

When considering a probiotic supplement, list the specific bacterial species and strains. The best formulas usually include several strains to help multiple digestive and immune systems simultaneously.

What Is CFU?

When comparing different probiotic formulations, looking at the number of colony-forming units (CFUs) contained in each product is common practice. CFUs are a unit of measurement that determines how many live bacteria cultures are present in a probiotic and how many of those cultures divide to form helpful colonies.

It is dependent on the intended purpose of the probiotics. A lower CFU count is good if your dog maintains healthy digestive and immune systems (between 3-10 billion CFU).

A high CFU count is desirable for treating various illnesses and health problems, including inflammatory bowel disease (IBD), food allergies, after treatment with antibiotics, and other instances. According to a number of studies, administering healthy dogs with probiotics containing a high count is not likely to result in any adverse effects.


  • It will help if you are looking for a probiotic blend that includes a prebiotic. Prebiotics help probiotics grow, which helps keep harmful bacteria under control in the dog’s gut.

Most Beneficial Bacteria Strains For Dogs

Probiotics for dogs often contain the bacteria species Bifidobacterium and Lactobacillus.

  • Bifidobacterium animalis is a type of bacteria that helps improve the overall health of your dog’s intestines. It can help to prevent inflammation and infection, as well as resolve canine diarrhea.
  • Enterococcus faecium helps to digest food and keep the stomach healthy. It also helps stop harmful bacteria, like Shigella, E. coli, and Salmonella.
  • Lactobacillus acidophilus helps protect the gut from bacteria and fungus. It can also help stop diarrhea that is caused by antibiotics. Finally, it may help reduce cholesterol levels and improve weight gain/growth in puppies and younger dogs.
  • Some bacteria, called L. fermentum, L. rhamnosus, L. salivarius, L. reuteri, L. Plantarum, and L. casei, are essential for gut microbiomes. They provide solid anti-microbial activity in the gut. They can also improve the gut’s health when it is unhealthy.
  • Pediococcus acidilactici is a bacteria that can treat constipation and diarrhea, relieve stress, and enhance the immune response. It also protects the small intestine from other harmful bacteria, like E. coli and Salmonella.

Probiotics for Dogs: The Health Benefits

Why do dogs need good microbes? Magic or mystery? Probiotics create healthy waste products because the bacteria thrive in the dog’s intestines. Stay with me; it’s weird. These microorganisms convert dietary fiber and plant-based sugars (FOS, MOS, GOS) into valuable metabolites. What’s the benefit? Microbes’ metabolic products helped build Nutrigenomics and advance health studies.

These byproducts are dog gold. No, they’re not gold particles but enhance your dog’s intestinal biology. Your dog doesn’t synthesize vitamins and short-chain fatty acids. The functional existence of microbial byproducts is directly and indirectly. Enhances body organ feedback mechanisms, cell wall strength, and immune function support, making these metabolic byproducts incredibly valuable. Life-dependent.

Many probiotics can positively impact canine intestinal health in ways we know and don’t know yet. If you believe I’m selling snake oil or puff science, think again. Probiotics need proper support to work. Reanimate, split, and thrive on fighting harmful bacteria aiming to destabilize the system (Think yeast species). Your dog makes probiotic-rich excrement without other support.

We call it “necrobiosis” when there are more good microorganisms in an animal’s stomach than bad ones. It is a natural state of the gut ecosystem. It is different from “dysbiosis,” in which potentially harmful microorganisms take over and make you sick. (1) Think about yeast overgrowth, bloating, and overgrowth of fungi in the GI system.

What Science Reveals About Probiotics

We can obtain additional information about rollovers from studies and data that do not focus on dogs. Since humans have a single-gastric digestive system, we get new knowledge and applications about gut bacteria (canines, swine, and poultry). In addition, human and production animal research receives more funding than canine research. Therefore, let’s examine what we do know.

So, what do the well-established studies reveal regarding the crucial function of Probiotics?

  • Allergy and atopic illness mitigation or prevention
  • Prevention and treatment of respiratory tract infections (common cold, influenza) and urogenital infections
  • Gut reduction of cancer-causing enzymes and bacterial metabolites
  • It enhanced metabolism activation, favorable effects on fat metabolism, and mineral absorption stimulation.
  • Lactose intolerance and antibiotic-associated diarrhea can be prevented and reduced in length.
  • Having inflammatory bowel disease (IBD), Leaky Gut Syndrome, EPI, a Helicobacter pylori infection, or bacterial overgrowth can have some sound effects.

Significant scientific advances indicate that probiotics have a greater impact on the health of all animal species:

1. The poultry industry funds numerous studies to measure the effect of pre-& probiotic injection into embryos. To better understand early animal gut microbiome development and create better food formulas and effects due to the importance of early gut microbiome development in fostering immune system development. (3) When was the last time you heard of pet food firms investing this much effort into producing dry food formulae for puppies?

2. Infection prevention of hazardous Lactobacillus strains prevents human UTI and bladder infections. Large intestine Campylobacter infection, bovine respiratory illness from Mannheim. Frequency of Salmonella infections in chicken enterprises.

3. Oral immunization provided mice 80 percent protection against E. coli 0157:H7 infection. Yeast, staph, and strep strains are more likely to cause oral infections when probiotics are in the toothpaste. Mouthwashes with probiotics help denture wearers with yeast infections.

4. Even researchers have investigated the effects of feline excrement microorganisms on dogs’ digestive health. Perhaps we will finally comprehend whether cat feces are harmful to dogs.

Comparing the Top Probiotics Factors for Dogs

What to search for:

With the current state of pet care advising consumers to feed highly processed, high-preservative dry kibble as the majority of a pet’s diet in addition to highly processed treats, the dog’s intestinal environment has no chance of achieving a healthy balance for long-term health effects. To ensure you’re not wasting time, money, or your dog’s health, we’ve developed the following guidelines to help pet owners catch up with 22 years of sophisticated feeding techniques. While creating Origins 5in1, we prioritized these criteria to ensure that it works in pet diets.

5 Rules of Probiotic Inclusion: Concentrate on “Probiotic Needs.”

1. pH Diet is the primary determinant. pH is essential for probiotics’ intestines. Dry dog food is not your dog’s friend since it quickly changes the stomach pH.

2. Diet Dry dog food fails our dogs. Species-appropriateness is crucial! Raw meats, bones, organs, and fermented foods create an excellent intestinal environment (yogurt, apple cider vinegar, Fermented turmeric & ginger).

3. Prebiotic support Keeping microbes need food. Microbes eat prebiotic fibers and plants. Bug-feed!

4. Bacteria Diversity Lactobacillus strain diversity improves overall canine health (skin & coat, allergies, metabolism, etc.). Certain sporulating strains act as “directors” for gut bacteria.

5. Potency Some numbers are important. As a metric, CFU should be utilized. Total CFU numbers matter since the adequate amount fluctuates based on the qualifiers. Origins 5in1 can improve health and performance with less CFU. Systems thinking is powerful.

The Best Rules for Probiotic Use

Probiotics need a conducive environment to work, but few know this. Probiotics require an appropriate environment to be effective. You’re wasting your money on probiotics. Suppose you’re feeding only dry dog food and expecting it to address pH or provide food for the organisms IF they try to develop. Separate these two points.

pH Role in the Gut Health Complex

Due to gut acidity, probiotics struggle. Unavoidably, some will perish. It’s called the “kill rate.” Figure 1 shows the canine digestive system’s pH range. These changes in gut pH support different microorganisms, creating diverse health effects. A bad diet of processed items and additives changes the small intestinal pH of the colon. Microbes’ lives depend on pH. Fish out of water? How may probiotic bugs grow in an unsuitable environment?

Diet Focus: Beneficial Partner or Benefit Leaching Blob

No supplement or pet food business tells you this. A bad diet can eliminate probiotic benefits. Prebiotics are important but useless without a comprehensive gut mentality (refer to rules above). Don’t squander money on kibble-only diets. Why?

Kibble becomes a big non-nutrient mass in the intestines, trapping nutrients, vitamins, and medications. It also adjusts pH to favor undesirable microorganisms and encourages disease growth (E. coli, Yeast, Campy, etc.). Origins 5in1 from Rogue Pet Science addresses all five probiotic rules in a kibble-based diet.

What Sources Can I Give My Dog As a Probiotic?

Pills, freeze-dried powders, and food-based probiotics are available for dogs. As marketing hype, some dog food producers add prebiotics.

Read labels to discover an easy-to-administer probiotic for your dog. Consider:

Probiotic Dog Food

It could be probiotic-fortified dog food or a topping. After leaving the facility, packaging and storage may reduce this probiotic’s efficacy. Probiotic dog food firms don’t brag about transforming lives unless it is in their marketing.

Probiotic Treats

You can use Soft treats to give your dog probiotics. Some treats may have additives that make probiotics ineffective—research before buying.

Probiotic Pills

 You can hide the Probiotic pills in dog food or treats. But be alert. Some dogs spit up pills.

Probiotic Powders

Live probiotic powder is easy to keep because the package controls oxygen and moisture, but giving it to your dog may require imagination. It is necessary to address the five foundations of gut health.

Natural Probiotic Food

These foods include probiotic microorganisms. Fermented foods like kefir include probiotics. Dogs shouldn’t eat all-natural probiotic meals. Contrary to popular belief, commercial yogurt and goat milk contain no probiotics.
