Unlocking the Potential of Probiotics for Your Canine Companion


Were you aware that a substantial 70% of your dog's immune system resides in their gut?
 Consequently, a myriad of complications and disorders can arise if your dog experiences subpar gut health. Issues ranging from inflammatory bowel disease to paw biting, scratching, and even tear stains may all stem from an imbalance of bacteria in your dog's system..

Nevertheless, the repercussions of poor gut health extend beyond the immediate. While it affects elements like immune response, it can also influence your dog's behavior, giving rise to problems such as anxiety and depression. In dogs, inadequate gut health can manifest in various ways, including:

  • Allergies
  • Skin Irritations and Itchy Skin
  • Chronic or Intermittent Diarrhea
  • Paw Biting & Licking
  • Gassiness, Flatulence, and Bloating
  • Behavioral Issues Linked to Anxiety
  • Nutritional Imbalance and Deficiencies
  • Yeast Infections

Advantages of Incorporating Probiotics 

Numerous scientific studies underscore the positive effects of probiotics on dogs. Packed with beneficial bacteria, probiotics, when consumed, actively combat harmful bacteria in your dog's gut. The benefits of incorporating probiotics include:

Top-notch Dog Probiotics Can:

Deter Paw Biting

Mitigate Allergies

Dminish Itching & Scratching

Prevent Diarrhea

Help Anxiety & Boost Mood

Reduce Excessive Shedding

Increase Muscle Mass

Prevent Yeast Infections

Ingredients To Look For In Dog Probiotics

Probiotic Dog supplements are NOT all the same. Veterinarian approval/recommendations and scientifically proven ingredients are vital:

Lactobacillus

The most effective family of bacteria to prevent harmful bacteria growth & boost immunity. This powerful probiotic has been thoroughly researched and has proven effectiveness.

Turmeric

A powerful natural ingredient to aid digestion, reduce inflammation of the gut and is a strong antioxidant.

Yucca Schidigera

This all-important ingredient improves digestion, serves as prebiotic fiber and helps strengthen stool.

Black Pepper

To maximize absorption of the Probiotic, calm the gut and produce critical stomach acid to kill bad bacteria.

Checklist For Effective Probiotics

It is important that you make sure to buy a Probiotic with the following, so that you do not waste money on ineffective products. Ensure your Probiotic has:

High Volumes of CFUs

CFUs are colony-forming units – the number of living microbes in the probiotics. We recommend 2+ Billion CFU.

Money Back Guarantee

Brands with a money back guarantee are more likely to have higher quality products and lower risks if they don't work.

Vital Ingredients

Ensure the probiotic follows the above recommended list of ingredients, to ensure effectiveness and safety.

Additional Nutrients

Opt for a probiotic that supports overall health with a balance of vitamins such as A and C, as well as minerals such as Manganese. These are important minerals that can help the overall health of your dog.

Probiotics can be fragile. Look for storage instructions and check this probiotic is formulated to contain live bacteria for its full life.

By containing over 2 Billion CFU of proven probiotic strains such as Lactobacillus, their product has shown the highest efficacy for pet owners looking to solve a range of symptoms.

When compared to other brands in the market, Petjoy Probiotics contained the highest dose of Probiotic and included recommended ingredients which other products failed to.

PetJoy has also added Yucca Schidigera which serves as a prebiotic fiber and reduces inflammation, which helps boost the effectiveness of their chew supplement and reducing poor gut health symptoms.

Pros

Fast Shipping

Made in US

No Dairy

Cons

Powder Form

Low Amount of CFUs

No Moneyback Guarantee

The Bottom Line

Nuscentia's probiotic supplement for dogs is second on our list, falling behind PetJoy primarily due to two big reasons. Firstly, this one is a powder form, which for many owners is a lot more inconvenient, worst yet, for the dogs themselves, it is not pleasant. Secondly, it has a very low count of CFU of just 1 billion, whereas our first choice has 2 billion.

What we did like about this product, was that it did not contain dairy, which can be beneficial if your dog has a sensitive gut. They also promise fast shipping and the product is made in the USA, which is always recommended.

Cons

Lacks Turmeric & Black Pepper

Harder To Digest,

Low Potency Per Chew

The Bottom Line

This probiotic is good quality, but does not contain all nutrients required for an all round gut health supplement. Namely, the absense of turmeric and black pepper, as well dried yucca, give it a lot to be desired. However it does have a good amount of CFU overall, but falls short on these highly beneficial added ingredients. Furthermore, the serving size of 2 chews means it has less potency per chew and is not as good value for money from first glance.

Pros

High CFU Count

Cons

Not Tailored For Dogs

Expensive

Unknown Brand

No Moneyback Guarantee

The Bottom Line

While this product has a fairly high CFU count, it is not formulated with just dogs in minds. Instead, it is for both cats and dogs, which is not recommended as their digestive systems are not identical. This could cause potential upset stomachs or other issues if you have a somewhat sensitive pet. Furthermore, this is not a well known brand, although it is made locally in the USA which is a plug. On pricing, these are not good value for money, so it falls to our fourth spot.

Poor Value For Money

Low CFU Count

No Turmeric

The Bottom Line

Last on our list are Only Natural Pet's probiotic product. This product fell short on quite a few reasons, firstly, they are not flavoured, which in our experience can lead to dogs not wanting to take them. Secondly and more importantly, there is no Turmeric nor a high CFU count, which generally results in poor results. Beyond that, there is no moneyback guarantee and so there is likely a lower chance of being refunded if no improvement is seen.
