You already know the significance of dog probiotic and the best ones. How will you choose the right formula for your dog then?

What to Look for in the Best Dog Probiotic

While there are no guidelines on the ideal dog probiotic formula, the following factors need to be kept in mind.

Bacterial Strain Diversity

Several bacterial strains in a product have the opposite effect of what you want for the health of your dog’s digestive system. Veterinarians recommend starting with some strains then work up on a gradual basis.

It is significant for a product to have a mixture of Lactobacilli and Bifidobacteria species since both are already studied for the effects.

Clear and Clean Labeling

Labeling transparency is associated with shelf stability and potency guarantee. The products need to disclose the ingredients, such as the additives.

This is significant to know, specifically if a canine is allergic to any substance or ingredient. This helps prevent supplements containing allergens. In addition, try checking whether the probiotic has guaranteed ingredient analysis.

Number of CFUs

Probiotic products contain varying numbers of CFUs. Some of these products have hundreds of millions while others have billions in every serving. This can be misleading as getting a product with 400 billion CFUs is easy to interpret as exceptional.

The right thing to do is to read between the lines since the value usually encompasses the whole product, not just a serving.

It is the insufficiency of knowledge on how much every dog needs and not really the amount of CFUs. Identifying the sufficiency of a billion of CFUs for their benefits on dogs.

It is wise to frequently begin with a smaller CFU number although fur parents may not have any idea of the natural beneficial bacteria in the guts of dogs. Try increasing the dosage to 200 million CFUs with the absence of beneficial effects within a time frame.

Shelf Stability and Potency Guarantee

Choose a probiotic that is stable, not just a potent one. These supplements originate from living microorganisms that seem to lose potency or decay. Find the reputable manufacturers, as well as the products developed in the U.S.

Consideration of Different Approach for Pet with Chronic Digestive Troubles

While probiotics are essential in mitigating pets’ digestive issues, simply adding the formula may be insufficient for more critical problems.

Why not try a fecal microbiota transplant which delivers a community of microbes to pets. This can be done through an enema in a clinic or through an oral capsule at home.

The Bottomline

Just like in choosing other dog supplies and supplements, picking the best dog probiotic can be a daunting task for fur parents. The guidelines provided above, however, will be helpful in making your selection as easy and as quickly as possible. You can always consult your vet as well for an excellent opinion. There are actually a lot instore for your pooch out there.
