Our best friends:

FidoSpore probiotic for Cats and Dogs.

Having a dog or cat is not only good for the human psyche but also incredibly beneficial for the human gut microbiome. Dogs and cats can strengthen the human gut microbiome by going out into the environment, collecting microbes in their nose and fur, and bringing them back into your home.

By doing this, they can help to diversify and strengthen your gut microbiome, but don’t forget that dogs and cats have their own gut microbiomes.

Did you know that dogs and cats can get leaky gut too? Or that this could be the underlying cause of their recurring rashes, diarrhea, bad behavior or poor wound healing?.

If the lining of your dog’s or cat’s intestines begins to deteriorate, then this opens the door for unwanted toxins and pathogens to enter circulation, triggering immune responses such as inflammation and allergic reactions anywhere in the body.

What causes leaky gut in dogs?

Cats and dogs, like humans, have sensitive GI tracts that are unfavorably affected by artificial food products, antibiotic overuse, gut infections, and glyphosate found in the air, water, and soil.1,2 As carnivores, cats and dogs are evolutionarily designed to eat meat, yet the main ingredients in most pet foods include wheat, corn, soy and low-quality animal byproducts. These foods, medications, and environmental toxins can irritate an animal’s GI tract, causing damage to the protective lining of the gut.

Pets love to get into things they aren’t supposed to, like rubbish, dead animals, and animal faeces etc. This puts them at risk of acquiring a GI infection, which can have negative long-term consequences on gut health. In fact, overgrowth of Clostridium perfringens, Salmonella species, and Escherichia coli are shown to cause inflammation and deteriorate the gut barrier, leading to leaky gut in cats and dogs.


What’s inside?

FidoSpore is the first pet probiotic supplement clinically proven to support digestive health and reduce leaky gut. Bacillus subtilis HU58 and Bacillus licheniformis (SL-307) are both spore-forming probiotics that produce digestive enzymes, strengthen the immune system, produce short-chain fatty acids, and maintain the gut barrier. Pediococcus acidilactici is lactic acid-producing bacterium that has a wide range of benefits in cats and dogs.

It has been used to treat dogs with digestive symptoms like constipation and diarrhea, as well as dogs infected by parvovirus. P. acidilactii is also known to crowd out unwanted pathogens like Shigella species, Salmonella species, Clostridium difficile, and E. coli. FidoSpore also contains defatted grass-fed beef liver extract added for flavor and aroma.

Recent Study:

A recent study examined the effects of FidoSpore on the occurrence of dysbiosis and leaky gut in dogs.5 Researchers at the University of Agricultural Sciences and Veterinary Medicine in Romania administered a daily probiotic supplement containing the strains Bacillus subtilis and Pediococcus acidilactici to 11 dogs for a total of 30 days.

Dogs were divided into two groups: healthy dogs with no GI distress and dogs with gut dysbiosis experiencing diarrhea and vomiting. Results indicated that in dogs with gut dysbiosis, GI symptoms were greatly reduced, or disappeared entirely.

Total body inflammation and leaky gut markers were also dramatically reduced. In addition, probiotics did not produce adverse symptoms in healthy dogs and appeared to reduce flatulence.

Probiotics for pets have remarkable abilities to improve digestive health, particularly in dogs. In contrast to antibiotics, probiotics work with the animal’s immune system to improve overall function, rather than simply killing off pathogens and many beneficial microbes in the process. Research highlights that probiotics like FidoSpore are effective, safe, and more cost-effective than many conventional treatments.
