Great Pet “Great Poop” features a holistic formula with a prebiotic, 2 billion CFUs, and digestive enzymes. It supports digestion and gut health with Inulin, made in a GMP-certified USA facility.
However, it's only available online, and some dogs dislike the chicken flavor. The soft chew form can be challenging to mix into meals.

.webp)
Recent scientific studies found that as much as 80% of your dog’s immune system is in their gut. Surprised? You’re not alone. Most dog owners are just discovering the importance of probiotics for their beloved friend’s health.
Probiotics ensure your dog lives longer and healthier. Who doesn’t want that? Keep reading to discover everything you need to know to give your pup the best care for their gut and overall health.
To begin with, we’ve all heard about the importance of probiotics for humans, but how does gut health impact dogs? What health risks, problems, and diseases stem from an unhealthy gut microbiome in dogs?
Problems linked to Poor Gut Health
Dogs with poor gut health are at greater risk of developing various diseases. Possible diseases and conditions include:
- digestive disorders
- skin rashes
- autoimmune diseases
- yeast infections
- emotional health
- bad breath

- allergies
- irritations

Getting your dog started on probiotics is straightforward once you understand what you need to look for in a probiotic. This ensures your pup gets the full benefits of a probiotic. The benefits and advantages of using a probiotic far outweigh the long-term cost,both monetarily and physically, of not providing a daily supplement.

Essential Nutritional Advantagesof Probiotics
Studies found that dogs fed probiotics had an improved ability to absorb essential nutrients and had better small intestine health than those dogs not given a probiotic supplement.These same studies also showed that dogs supplemented with probiotics had a higher production of beneficial bacteria, which increased their overall health and immunity.
Probiotics Aided With The Following:
Look For These Required Ingredients
Don’t be fooled. Not all probiotic products are created with the highest degree of care and purity of ingredients. Getting a proven, tested probiotic product is critical to your pet’s health. Using ONLY high-quality probiotics ensures effectiveness and desired health results. The main 3 components to look for in a high-quality probiotic are the specific strains of bacteria, the CFU number, and a prebiotic.
Lactobacillus
The most widely studied and most effective bacteria in boosting immunity while helping to prevent harmful bacteria overgrowth. Watch for Lactobacillus acidophilus, lactobacillus bulgarius, and Lactobacillus reuteri.
Prebiotics
Prebiotics are non-digestible compounds in food that actually trigger the growth of healthy bacteria in the gut. They naturally occur in many fruits and vegetables, especially those that contain complex carbohydrates, such as fiber. Prebiotics increase the effectiveness of a probiotic.
CFU Number
Must have at least 2 billion CFUs (colony-forming units) present. The CFU number refers to the actual number of live and active microorganisms that are present in each serving of the probiotic.
Bifidobacterium
Accounts for more than 80% of microorganisms within the intestine and is also one of the most prevalent species residing in the mouth. Look for: bifidobacterium bifidum.
To Get The Best Product, Follow This Checklist
Wondering how you can most improve your dog’s gut health with so many products on the market? Our probiotic checklist below makes it easier than you think!
Most Effective Bacteria
Lactobacillus. Bifidobacterium. Bacillus Subtilis. Ensure that your product has at least one, if not more, of these three potent bacteria strains.
