7 Best Prebiotics for Dogs
Prebiotics for dogs are the unsung heroes of the canine gut. Probiotics tend to get all the attention, but prebiotics serve a very useful, distinct, and viable purpose in your dog’s overall digestive health. At least 70 percent of your dog’s immune system is in his gastrointestinal (GI) tract (1), so you can imagine why it is important to keep harmful bacteria out of it.
Incorporating a quality prebiotic into your dog’s diet may help boost his immune system, keep his gut healthy, promote bone strength, and balance blood sugar levels (2). But like dogs, no two prebiotics are the same. We’ll break down exactly how prebiotics work, plus share our recommendations for the best prebiotics for dogs.
What Are Prebiotics for Dogs?
As pet parents seek a healthier lifestyle for themselves, they also want to support the overall well-being of their four-legged family members. Not surprisingly, a need arose in the canine marketplace to address gut balance, flatulence, digestive upset, and conditions like inflammatory bowel disease. Enter prebiotics.
The International Scientific Association for Probiotics and Prebiotics defines prebiotics as “a substrate that is selectively utilized by host microorganisms conferring a health benefit.” (3) Translated in simpler terms, prebiotics serve as a food source for good bacteria in your dog’s gut. This helps prevent nasty microorganisms from growing and thriving (1).
Manufacturers know dogs are individuals, so what works for your pup may not work for another. We’ve become savvier and more knowledgeable about what goes into our dogs’ bodies. Therefore, prebiotics are available in various forms, including:
Apple and banana are high-fiber foods that are also good sources of prebiotics, but trying to work them into a dog’s diet can be difficult. Oftentimes, it’s easier and more effective to supplement with a well-researched, high-quality prebiotic that contains everything your dog needs.
Prebiotic vs Probiotic for Dogs
When comparing a prebiotic vs probiotic for dogs, remember that prebiotics help probiotics sustain themselves. “The difference between a probiotic and a prebiotic for dogs is that a probiotic adds to the beneficial bacteria to your dog’s gut and a prebiotic aids in maintaining them so they flourish within your dog’s stomach,” says veterinarian Dr. Brian Evans, clinical director of the pet telemedicine service Dutch.
When prebiotics work in tandem with probiotics for the overall good of your dog’s gut and immune system, a synbiotic relationship exists (4). For this reason, you’ll often see prebiotics paired with probiotics in many products.
Prebiotics for Dogs: What to Look For
Because dietary supplements like prebiotics and probiotics are not as heavily regulated as medications, veterinarian-developed and veterinarian-recommended options are the right choice to ensure effectiveness and safety, Evans says.
When purchasing a prebiotic for your dog, consider the following:
- Does the product contain natural ingredients?
- Is the product veterinarian developed or recommended?
- Is the product designed specifically for dogs?
- Will it be easy to give to my dog?
- Did my veterinarian recommend or agree that I can give my dog this type of product?
- Has any third-party testing been done on the product?
- How should the product be stored?
There should never be any artificial sugars or sweeteners, such as xylitol, in any products you give your dog. Ask your veterinarian if your dog is already receiving an adequate amount of prebiotics in his dog food or if supplementing will be beneficial.

Prebiotics for Dogs: Tips and Advice
Always store prebiotics as indicated on the manufacturer’s product label. Since many prebiotic products also contain probiotics, which are live microorganisms, they may need to be refrigerated. “It is important that pet owners store probiotics as directed to avoid killing off the bacteria and ruining its effectiveness,” Evans says. Prebiotics are more durable, so standalone products do not need to be refrigerated unless otherwise indicated by the manufacturer.
Never give your dog multiple prebiotic products at one time, as he can suffer a host of side effects, ranging from diarrhea to dehydration. It is best to start slow when adding anything new to your dog’s diet to ensure the product agrees with his system.
Do not give your dog a prebiotic or probiotic intended for humans. The product you use should be specifically formulated for dogs.
Prebiotics can aid in your dog’s digestion so nutrients are better absorbed and his immune system can perform at its full potential. Always talk to your veterinarian if you notice any side effects or worrisome changes in your dog’s bowel movements or digestion.
