Gut health is emerging as a major area of focus in the growing pet supplement category, yet a gap remains: while interest in gut health support is higher than ever for humans, fewer than one-third of dog and cat owners give their pets supplements specifically designed to support the gut.
Why gut health matters
Gut health has been making headlines for good reason. The gut microbiome — the community of microorganisms living in the digestive system — plays an important role in many of the body's key functions, influencing immune response, skin health, mood and nutrient absorption, among other things.
The same is true for pets. When the gut is out of balance, it can show up in a variety of ways, from itching and seasonal allergies to low energy and digestive issues.
Symptoms of gut imbalance
If your four-legged family member isn't eating well, has changes in stool or bowel habits, or you notice frequent stomach gurgling, it could be a sign their gut needs additional support. Other common symptoms include gas, bloating, diarrhea, scooting and loss of appetite.
Gut disruption can have many causes, including antibiotic use, food transitions, travel, stress and tension, aging or breed-specific sensitivities, and even puppies can benefit from early microbiome support.
Fortunately, many of these digestion challenges can be addressed with the right kind of daily support. By focusing on key ingredients that promote a balanced microbiome, pet owners can help improve digestion and overall well-being. One of the most important steps is understanding the three key components of digestive health: probiotics, prebiotics and postbiotics.
The difference between probiotics, prebiotics and postbiotics
You've likely heard of probiotics, but supporting digestive health — for both humans and pets — involves three key components:
1. Probiotics are the "good bacteria" that support digestion, aid nutrient absorption and help maintain immune health. When given as a supplement, they help reinforce the population of beneficial bacteria in the gut.
2. Prebiotics act as fuel for the probiotics. These indigestible fibers nourish probiotics and help them grow and thrive.
3. Postbiotics are the beneficial compounds produced when probiotics break down prebiotics. These byproducts — such as short-chain fatty acids, enzymes and vitamins — help support a healthy gut environment and make it more difficult for harmful bacteria to survive.
Together, prebiotics, probiotics and postbiotics create a more balanced and resilient gut microbiome.
How to find good gut health supplements
Rather than waiting until a problem arises with your dog or cat's digestive system, you can be proactive by giving them the daily digestive support they need. Here's what you should look for in a digestive support supplement:
Proven ingredients: well-researched strains like Bacillus subtilis (a hardy probiotic) and Lactobacillus rhamnosus.
Balanced formulation: a combination of prebiotics, probiotics and/or postbiotics that work together to support a healthy gut microbiome.
Form your pets will take: soft chews or powders
Third-party tested: quality products with ingredients tested for stability and safety, manufactured in audited facilities.

"A proactive approach to digestive health can help your dog or cat thrive," said Dr. I. Craig Prior, BVSc, CVJ. "Just as many people take a daily supplement for digestive support, your pet can benefit from a proactive approach to gut health. Supporting their microbiome through their daily routine helps with better digestion, immune function and overall vitality."
Before incorporating a digestion supplement into your pet's routine, consult your veterinarian to ensure it's appropriate for their needs.
