A dog or cats microbiome is composed of communities of bacteria (and viruses and fungi) which live all over the body, but primarily in the gut. It is responsible for an extensive array of functions, including development of immunity, pathogenic defense and of course securing adequate nutrition. The microbiome is basically a mini-ecosystem which is extremely important in the well being of your pet. It is so important that it is sometimes called the “forgotten organ”.

One of the major functions of the microbiome is to support the immune system through working closely with the GALT or gut-associated lymphoid tissue in the gut. The GALT is actually a mucus membrane that lines the intestinal tract and with your pets microbiome makes up over 80% of the immune system!

A healthy gut can house at hundreds if not thousands of different species of bacteria; but a pets microbiome is not static and can change depending on what it eats and its environment.

Think of the microbiome as a little army inside your pets (and your) body. When they are compromised or killed off the bad guys are able to come in and basically destroy whatever they want.

The diversity and numbers of microbes can be affected by multiple factors including infection, stress, nutrition, disease and of course antibiotic use.

If the beneficial bacteria are wiped out or greatly diminished for some reason and bad or pathogenic bacteria are allowed to flourish this can wreak havoc on your pets GI and immune system. You will then start to see diseases such as IBD, diarrhea, weight changes, dullness of coat and Dysbiosis.

Here are four things you can do to ensure your pets microbiome remains in tact and full of healthy bacteria

Feed Healthy Foods

Avoid genetically modified foods, foods high in preservatives and artificial flavors. It is best to feed whole and fresh foods even if you have to add some to your dogs kibble. Some pet owners even go as far as feeding raw food which has been shown to increase the bacteria in your pets microbiome, you can read about that in this article.

Feed Pre and Probiotics

Probiotics are full of beneficial bacteria. Make sure to research high quality probiotics that are free of fillers and artificial junk, if you are looking for some great natural choices you can read our article about four that we think are great.

Probiotics will help restore your pets microbiome so definitely administer them if your fur baby is on any type of antibiotic. Many owners find pellets easier to administer than powder, but of course see what works best for your pet.

Another great way to add probiotics is to give fermented foods like plain low-fat yogurt or kefir. Most pets love them and a small amount usually goes a long way. Of course you will want to discuss this with your vet first to get an appropriate dose.

Always make sure you give a prebiotic or that your probiotic comes with a prebiotic. Read more about choosing a good probiotic for your pet here.

Avoid Killing Off Beneficial Bacteria

This goes without saying but sometimes we may not be aware of how our choices affect our pets microbiome. Chemicals such as pesticides on the grass can cause a plethora of issues including killing off your pets microbiome, so for those of us that have pets that are perpetual grass eaters make sure to lay off the pesticides. Seek out natural alternatives whenever you can.

While there will be times antibiotics can not be avoided, you will want to quickly replenish your pets microbiome with probiotics. Antibiotics wipe out beneficial and pathogenic bacteria so it may be necessary to add them back into your pets intestinal system.


There’s a reason our guts are deemed a ‘second brain’ because there is something to be said about the gut brain connection. Stress can cause your pet to have a decrease in beneficial microbial population and alter the regulation of neurotransmitters mediated by the microbiome.
