When most people hear the word probiotics, they immediately think about digestion. And for good reason! These beneficial bacteria are well-known for supporting a healthy gut, improving digestion, and helping maintain a balanced microbiome.
But your pet’s gut is connected to almost every system in their body. From immunity to inflammation, metabolism to mood, the tiny microorganisms living in the digestive tract play a much bigger role than we once understood.
One of the most exciting areas of research is the connection between probiotics and heart health in dogs and cats. A healthy microbiome may help support the cardiovascular system in several important ways, making probiotics a valuable part of an overall wellness plan.
The Gut-Heart Connection in Pets
The gut and heart might seem like they have nothing to do with each other, but they are closely connected through what is known as the gut-heart axis. (You may have heard us talking about the gut-brain axis before – this is the same.)
The gut microbiome (the community of bacteria, yeast, and other microorganisms living in the digestive tract) helps regulate:
- Inflammation
- Immune function
- Metabolism
- Blood pressure
- Cholesterol balance
- Oxidative stress
When the gut microbiome becomes unbalanced (known as dysbiosis), it can contribute to chronic inflammation and other changes throughout the body. Since ongoing inflammation is linked to many health issues, including cardiovascular concerns, supporting the gut may also help support the heart.
How Probiotics Benefit Heart Health in Dogs and Cats
There are several reasons to embrace the power of probiotics for heart health.
1. Help Reduce Inflammation
Chronic inflammation can put stress on the cardiovascular system. An unhealthy gut microbiome may contribute to increased inflammatory signals throughout the body.
Certain probiotic strains help support the production of beneficial compounds and promote a healthier balance of gut bacteria. This can help maintain a calmer inflammatory response.
For dogs and cats, keeping inflammation balanced is important for protecting overall wellness, including the heart.
2. Supporting Healthy Blood Pressure
Blood pressure regulation is influenced by many factors, including the nervous system, kidneys, diet, and the gut microbiome.
Some beneficial bacteria produce compounds called short-chain fatty acids (SCFAs), which help support healthy blood vessel function. Healthy blood vessels are essential for maintaining normal circulation and reducing strain on the heart.
3. Supporting Healthy Cholesterol and Fat Metabolism
The gut microbiome helps process nutrients, including fats. Certain beneficial bacteria may influence how the body absorbs and uses cholesterol.
A balanced microbiome may support healthier lipid metabolism, which is important because abnormal fat levels can contribute to cardiovascular stress.
4. Improving Immune Balance
A large portion of the immune system is connected to the gut. When the gut is healthy, the immune system is better able to respond appropriately.
Probiotics can help support immune balance by encouraging beneficial bacteria and helping prevent harmful bacteria from taking over.
A balanced immune response helps reduce unnecessary inflammation that can affect many organs, including the heart.
5. Supporting a Healthy Weight
Maintaining a healthy weight is one of the most important ways to support heart health in pets.
The gut microbiome plays a role in:
- How nutrients are absorbed
- How energy is used
- Appetite regulation
- Metabolism
A healthy gut supported by probiotics, a balanced diet, and regular exercise can help pets maintain an ideal body condition and reduce strain on the cardiovascular system.
6. Supporting Pets with Age-Related Changes
As dogs and cats age, their microbiome can change. Older pets may experience slower digestion, changes in metabolism, increased inflammation, and other age-related challenges.
Supporting the gut with probiotics may help senior pets maintain better overall balance, which supports their heart, immune system, and quality of life.

Where to Find Probiotics for Dogs and Cats
There are several ways to add beneficial bacteria to your pet’s routine.
1. Probiotic Supplements
A high-quality pet probiotic supplement is often the easiest and most reliable way to support gut health.
Look for products that:
- Contain multiple strains of beneficial bacteria – more strains gives your animal access to greater bacterial diversity
- Provide an appropriate amount of colony-forming units (CFUs) – a higher CFU count can mean a greater concentration of live and active microorganisms reaching the gut
- Are made specifically for pets – human probiotics can contain ingredients that are not well-suited to our adored beasts
- Include strains that are well-researched for animals – including species-specific strains like those found in our Fido’s Flora and Felix’s Flora
2. Fermented Foods
Some fermented foods naturally contain beneficial bacteria and can be added in small amounts to a pet’s diet.
Options may include:
- Plain kefir (unsweetened and free from artificial sweeteners)
- Fermented vegetables (without added salt, garlic, or harmful seasonings)
- Small amounts of plain yogurt if your pet tolerates dairy
- Make your own so you know exactly what’s in the jar – here’s our recipe
Always introduce fermented foods slowly, since too much too quickly can cause digestive upset.
3. Fresh, Whole Foods
A diverse diet supports a diverse microbiome. Feeding a variety of appropriate whole foods can help create an environment where beneficial bacteria thrive.
A fresh diet that includes different proteins, fibre sources, and nutrients can help nourish the microorganisms that support your pet’s health.
Don’t Forget About Prebiotics!
Probiotics get a lot of attention, but they need support too.
Prebiotics are the food source that feeds beneficial bacteria. Think of them as fertilizer for the good microbes in your pet’s gut.
Without enough prebiotics, probiotics may not thrive as well.
Common sources of prebiotics include certain types of fibre found in foods like:
- Pumpkin
- Chicory root
- Jerusalem artichoke
- Asparagus
- Leafy greens
- Berries
- Bananas
- Watermelon
QUICK TIP: Some quality probiotic supplements also include prebiotics, often called synbiotics, because they combine beneficial bacteria with the nutrients that help them grow. Hint: All Adored Beast probiotics feature a blend of probiotics and prebiotics!
A Healthy Gut Supports a Healthy Heart
Your dog or cat’s health is all connected. The gut is not just a digestive organ – it is a major communication center that influences many systems throughout the body.
And probiotics can be an important piece of a proactive wellness plan.
By supporting a balanced microbiome with probiotics, prebiotics, fresh nutrition, and exercise, you are helping support your pet’s overall health – including their heart.
