WHICH PROBIOTIC CHEWS FOR DOGS CONTAIN THE BEST INGREDIENTS?

PREBIOTICS

Prebiotics are non-digestible food ingredients that serve as food for beneficial bacteria in the gut, promoting their growth and improving gut health. In recent years, prebiotic supplements have become increasingly popular for dogs, for the purpose of improving digestive health, strengthening the immune system, and reducing inflammation.

One study published in the Journal of Veterinary Internal Medicine in 2019 examined the effects of a prebiotic supplement on dogs with chronic diarrhea. The study found that dogs who received the prebiotic supplement had significant improvements in stool consistency and frequency, as well as reduced inflammation in the gut.

SPORE FORMING BACTERIA STRAINS

BC30 (Bacillus coagulans GBI-30, 6086) is a spore-forming probiotic strain that has been studied for its potential benefits to gut health in dogs for its ability to survive the harsh conditions of the digestive tract and potentially provide health benefits such as digestive health, strengthen the immune system, and even reduce anxiety in dogs.

A study published in the Journal of Animal Science in 2020 examined the effects of Bacillus coagulans supplementation on the immune system and digestive health of dogs. The study found that dogs who received the supplement had increased levels of beneficial bacteria in their gut, as well as improved immune function.

Another recent study in May 2021 Department of Grain and Science at Kansas State University Conducted research to see how Bacillus coagulans affects the quality of dog stool, the digestion of nutrients, and markers of intestinal health in healthy adult dogs. The study involved 10 adult beagle dogs living individually. They were given different diets with varying amounts of Bacillus coagulans, either mixed into the food before cooking or applied on the surface of the kibble after cooking. The dogs were observed for 16 days, and their feces were collected for analysis during the last 5 days.

The results showed that the dogs that received the highest dose of Bacillus coagulans had better digestion of organic matter, protein, fat, and energy compared to the dogs in the control group. However, there were no significant differences in food intake, stool quality, or other markers of gut health between the dogs that received Bacillus coagulans and those in the control group. This suggests that adding Bacillus coagulans to dog food at a daily intake level of up to 9-log10 colony-forming units can improve nutrient digestion without causing any apparent negative effects in healthy adult dogs.

INGREDIENTS TO AVOID IN DOG PROBIOTIC CHEWS

Xylitol - This artificial sweetener is toxic to dogs and can cause seizures, liver failure, and even death in some cases.

High levels of vitamin D - Excessive levels of vitamin D can lead to hypercalcemia, a condition where there is too much calcium in the blood, causing kidney damage and other health problems.

Artificial preservatives - BHA, BHT, and ethoxyquin are some of the artificial preservatives that may cause cancer and other health issues in dogs.

Gluten and grain - Dogs may have difficulty digesting gluten and grains, which can lead to digestive issues and allergies.

KEY INGREDIENTS TO LOOK FOR IN DOG PROBIOTIC CHEWS

High CFU Count - CFU stands for Colony Forming Units, and a high CFU count in dog probiotic chews indicates the presence of a large number of live beneficial bacteria that can help support the dog's digestive health.

Prebiotics - Prebiotics are non-digestible fibers that serve as food for the beneficial bacteria in the dog's gut, promoting their growth and activity and enhancing the overall balance of the gut microbiome.

Bacillus Coagulans - Bacillus coagulans is a spore-forming probiotic strain commonly found in dog probiotic chews. It has the ability to survive harsh conditions in the gastrointestinal tract, reach the intestines alive, and support digestive health by promoting the growth of beneficial bacteria.

Spore Forming Strains - Notable examples of spore-forming bacteria are Bacillus and Clostridium. Capable of forming highly resistant structures known as endospores, spore-forming bacteria can survive in challenging environmental conditions, including high temperatures, desiccation, and exposure to disinfectants. Endospores remain dormant for extended periods until favorable conditions arise, at which point the bacteria can germinate and resume growth.

Other Helpful Ingredients:
  • Bacillus subtilis
  • Chicory Root
  • Manganese
  • B Vitamins
  • Folic Acid
  • Flaxseed

While a high CFU count is generally considered beneficial for dog probiotic chews, it's important to note that CFU count is not the only factor to consider when choosing a probiotic supplement for your dog. For example, a probiotic supplement with a high CFU count but low-quality or ineffective strains of bacteria may not provide any benefits to your dog's digestive system. One good example is Bacillus Coagulans. Bacillus Coagulans is a unique probiotic strain that can survive harsh digestive conditions. Unlike other probiotics, it has a natural protective layer that allows it to survive the acidic environment of the stomach and reach the intestines, where it can deliver its health benefits.

Study 1: "Bacillus Coagulans improves gut health and immunity in dogs." Journal of Applied Microbiology, 2016. This study evaluated the effect of BC30 on the gut health and immunity of dogs, and found that it improved the balance of beneficial bacteria in the gut and enhanced immune function.

Study 2: "Bacillus Coagulans improves digestive function in healthy dogs." Journal of Animal Science, 2018. This study found that BC30 was effective in improving the digestion and absorption of nutrients in healthy dogs, leading to improved stool quality and overall digestive health.

THE BOTTOM LINE

Pawfy Probiotic ranks #3 in our list. The product is formulated to address gut health issues such as digestive functioning, immune support.

Despite its claim of being a soft chew, some dog owners reported on review sites that these bacon or duck-flavored tablets were difficult for their dogs to chew. Some dogs also refused to take them due to its odor. This is why, despite its considerable ingredient list, Pawfy Probiotic only ranks #3.
