For years, pet nutrition conversations focused almost entirely on protein and fat. But today, veterinarians and nutrition researchers are paying just as much attention to something else: the gut microbiome.
Inside your dog’s digestive system lives a vast ecosystem of bacteria that influences digestion, immune function, skin health, and overall wellbeing. When that ecosystem is balanced, dogs tend to have better stools, fewer digestive problems, and stronger immune resilience.
One of the most powerful ways to support this system is through prebiotics.
While many pet parents think of prebiotics as plant fibers like pumpkin or chicory root, there’s another fascinating source that naturally supports gut bacteria: insect protein.
Insects contain a compound called chitin, a natural fiber found in the exoskeleton of crickets and other insects. Chitin functions as a prebiotic, feeding beneficial bacteria in the digestive system and helping maintain a healthy microbiome.
That means insect protein does something unusual: it provides complete protein nutrition while also supporting gut bacteria.
Let’s take a closer look at how it works — and why it matters for dogs with sensitive stomachs, chronic diarrhea, or digestive issues.
First, a quick refresher: what is a prebiotic?
If you’ve ever heard the terms probiotics and prebiotics, you might have wondered what the difference is.
You explained it perfectly in your earlier blog:
-
Probiotics introduce beneficial bacteria into the gut
-
Prebiotics feed the beneficial bacteria already living there
Prebiotics are typically fibers that travel undigested through the stomach and small intestine. Once they reach the colon, beneficial bacteria ferment them and produce compounds called short-chain fatty acids (SCFAs).
These molecules play a major role in digestive health. They help:
-
nourish cells lining the colon
-
maintain fluid balance in the gut
-
inhibit harmful bacteria
-
support a stable microbiome
When your dog regularly eats foods that contain prebiotics, it helps maintain the balance of beneficial microbes in their digestive system.
And that balance affects much more than digestion.
Why the gut microbiome matters for dogs
Your dog’s gut microbiome influences many aspects of health, including:
-
digestion and stool quality
-
immune function
-
inflammation levels
-
skin and coat health
-
nutrient absorption
In fact, the digestive system is closely connected to the immune system. A healthy microbiome helps regulate immune responses and maintain the integrity of the gut barrier.
When the microbiome becomes imbalanced, dogs often experience symptoms like:
-
chronic diarrhea
-
loose stools
-
gas or bloating
-
sensitive stomach
-
recurring digestive upset
Supporting beneficial bacteria through prebiotics can help restore balance.
And that’s where insect protein becomes particularly interesting.
Insect protein contains a natural prebiotic: chitin
Insects are structurally different from traditional animal proteins like chicken or beef.
Instead of bones and connective tissue, insects have an exoskeleton made of chitin.
Chitin is a complex carbohydrate fiber that animals — including dogs — do not fully digest. Instead, it travels to the large intestine where beneficial microbes can ferment it.
This fermentation process feeds helpful bacteria and contributes to the production of short-chain fatty acids that support intestinal health.
In other words, chitin acts as a natural prebiotic fiber.
Research has shown that insect-based ingredients can help support the development and maintenance of a healthy microbiome by feeding beneficial gut bacteria and inhibiting harmful microbes.
That’s one reason insect-based diets are gaining interest in veterinary nutrition.
What the research says about insect protein and the gut microbiome
Several studies have examined how insect-based diets affect digestion and microbial populations in dogs.
In one study evaluating dogs fed diets containing house cricket protein, researchers analyzed fecal microbiota to understand how the diet affected gut bacteria.
The results showed that insect-based diets were well tolerated and did not negatively affect the overall microbial balance, while certain beneficial bacteria increased.
Other research has shown that insects contain compounds that support healthy gut microbes and provide valuable nutrients at the same time.
These findings support what many veterinarians are beginning to recognize: insect protein can support digestive health in multiple ways.
The study behind Jiminy’s cricket protein research
One of the key studies examining insect protein and dog health was published in the Journal of Animal Science (PMID: 32179914).
In that study, researchers evaluated the effects of cricket protein in dog food and found that it provided excellent digestibility and nutritional value for dogs.
The findings showed that cricket protein can serve as a high-quality, highly digestible protein source, comparable to traditional animal proteins.
This is important because digestibility plays a major role in gut health.
When protein is easily digested and absorbed, less undigested material reaches the colon — which helps maintain a more balanced microbial environment.
If you want to dive deeper into the science behind digestibility, see:
THE DIGESTIBILITY OF INSECT PROTEIN FOR DOGS
Why digestibility matters for dogs with sensitive stomachs
Many digestive problems in dogs stem from poorly digested ingredients.
When proteins are difficult to digest, more undigested nutrients reach the large intestine. There, bacteria ferment them in ways that can produce gas, irritation, and loose stools.
Highly digestible proteins help avoid this issue.
Insect protein has been shown to provide excellent digestibility in dogs, meaning their bodies can efficiently absorb nutrients while producing less digestive waste.
For dogs prone to stomach upset, that can make a meaningful difference.
Insect protein and dogs with chronic digestive issues
Dogs experiencing recurring digestive issues often benefit from two things:
-
A novel protein source
-
Support for the gut microbiome
Insect protein provides both.
Because most dogs have never eaten insects before, cricket protein is considered a novel protein. That means the immune system is less likely to react to it compared to common proteins like chicken or beef.
At the same time, the chitin in insects provides natural prebiotic support.
This combination makes insect protein particularly helpful for dogs experiencing:
-
chronic diarrhea
-
frequent gas
-
sensitive stomachs
-
food sensitivities
-
digestive inflammation
Many veterinarians recommend novel protein diets specifically for dogs with these types of digestive issues.
How insect protein helps support the microbiome
The benefits of insect protein for gut health come from several complementary factors.
natural prebiotic fiber
Chitin feeds beneficial bacteria in the digestive tract, helping maintain microbial balance.
highly digestible protein
Easily absorbed nutrients reduce the amount of undigested material reaching the colon.
immune-friendly novel protein
Because dogs rarely encounter insects in their diets, the immune system is less likely to react to them.
Together, these factors support a healthier digestive environment.
Where Jiminy’s Cravin’ Cricket fits in
Jiminy’s Cravin’ Cricket dog food was designed specifically with these principles in mind.
The recipe uses cricket protein as the primary ingredient, providing a highly digestible novel protein source that is gentle on sensitive stomachs.
At the same time, the natural chitin in cricket protein functions as a prebiotic, helping feed beneficial gut bacteria and support a balanced microbiome.
As discussed in your earlier article on insect protein and gut health:
Crickets contain high levels of prebiotic materials that help your dog’s microbiome grow and thrive.
The result is a food that supports digestive health in multiple ways.
For dogs with chronic digestive issues, many pet parents notice improvements such as:
-
firmer stools
-
reduced gas
-
less digestive upset
-
improved overall comfort

A gut-friendly protein that also helps the planet
There’s one more benefit worth mentioning.
Cricket protein isn’t just good for dogs — it’s also dramatically more sustainable than traditional livestock protein.
Crickets require far less:
-
land
-
water
-
feed
-
greenhouse gas emissions
So when pet parents choose insect protein, they’re supporting both their dog’s gut health and the planet’s health.
