GENRIC Pet insurance is the newest and most innovative pet medical insurance product (not a pet medical aid) in South Africa. It is designed to cover the unexpected, unforeseen and fortuitous veterinary costs that cats and dogs kept as household pets may incur as a result of illness or injury. its development took cognizance of the strengths and weaknesses of of other policies and therefore avoids their shortcomings from day one. www.genricpet.co.za


Probiotics get the spotlight....but meet the unsung hero - Prebiotics!

Friends of the Dog

You’ve probably heard of probiotics — those supplements or chewie treats loaded with “good” bacteria to help with digestion, bad-gut days, or after antibiotics. But there’s another player in the game called prebiotics, and while they don’t get quite as much spotlight, they do something pretty cool. As with all supplements you add to your dog´s diet, always check with your vet first to ensure they are beneficial for your dog. 

What are prebiotics, really?

Think of prebiotics like fertilizer for the helpful bacteria already living in your pet’s gut. Instead of introducing new bacterial colonies (like probiotics do), prebiotics feed and support the beneficial ones already there.

From a scientific standpoint, the International Scientific Association for Probiotics and Prebiotics (ISAPP) defines them as:
“Selectively fermented dietary ingredients that result in specific changes in the composition and/or activity of the gastrointestinal microbiota, thus conferring benefit(s) upon host health.”

So, prebiotics target the existing ecosystem of microbes (in the gut), helping the “good guys” grow stronger rather than introducing new ones directly.

What benefits do prebiotics bring?

Here’s what recent research and experts suggest prebiotics can do for pets:
  • They help improve digestive health: better stool consistency, fewer gut upsets, and improved absorption of nutrients.
  • They promote gut environment balance: more beneficial bacterial species (like Bifidobacteria and Lactobacilli), reduced overgrowth of harmful/pathogenic bacteria. 
  • They support immune function: since a large part of immunity is tied to gut health, healthier guts tend to mean stronger immune responses. 
  • Possible metabolic and systemic benefits: improved lipid metabolism, better mineral absorption, possibly helping with obesity or managing blood sugar.
  • They can help pets recover after disturbances: e.g. after antibiotic use, during stress, or dietary changes. Prebiotics help "reset" or support the recovery of a healthy microbiome. 

What about probiotics — how do they fit?

Probiotics are the live strains of beneficial bacteria you add into your pet’s GI tract (via food, treats, powders). They’re super useful when there’s an acute problem: diarrhea, bacterial overgrowth, etc. They help out by:
  • Restoring balance when harmful bacteria have overrun things.
  • Competing with bad bacteria for space/resources.
  • Producing substances (e.g., short-chain fatty acids) that can lower gut pH, discourage pathogens, and help feed the gut’s own cells.
Prebiotics can complement this — feeding and supporting both the native bacteria and possibly those probiotic strains you introduce.

Things to watch out for (yes, there are some)

Like most things, the dose and type matter. Here are some caveats and things to keep in mind so your pet gets the benefit without the mess:
  • Too much, too fast: Overdoing prebiotics can lead to increased gas, bloating, loose stools or diarrhea, especially in pets with sensitive guts. 
  • Formulation matters: Some prebiotics are more studied, more pure, or more digestible. Not all are the same. FOS (fructo-oligosaccharides), inulin, MOS (mannooligosaccharides), GOS (galactooligosaccharides) are some commonly used forms.
  • Underlying health conditions: Pets with immune system issues, certain GI diseases, or those very young or old may need more careful monitoring when using pro-/prebiotics. As we said earlier, always good to check with your vet. 
  • Interactions with diet: If your pet’s diet is already high in fermentable fibers (natural sources), adding more might push things over the edge. Also, diet type (meat-based vs plant-based) affects how much extra prebiotic might help.

How to use them wisely
  • Start slow: Introduce prebiotics gradually so the gut can adapt.
  • Check the label: Always look for published studies or vet-recommendations backing the product.
  • Think diet first: Some pet foods already include prebiotics. If that’s the case, extra supplementation might be unnecessary (or just a tweak). 
  • Pair with probiotics if needed: For certain situations (after antibiotics, GI upset), using both can give a double boost — probiotics to replenish, prebiotics to feed.

Additional Insights from Recent Research

Here are some of the newer findings and perspectives (2024-2025) worth knowing:
  • Studies show that in both dogs and cats, probiotics can help with restoring microbial diversity after disruptions from antibiotics, illness, or poor diet. MDPI+2PMC+2
  • Research on prebiotic content in commercial pet foods suggests most include < 0.5% prebiotics of the total formulation to avoid side effects. isappscience.org
  • There’s interest in newer or less common prebiotic sources — for instance, certain plant-based or yeast‐based oligosaccharides, and even mimics of milk oligosaccharides, which might have special benefits. isappscience.org
  • For cats, synbiotic products (those combining prebiotics + probiotics) are showing promise in improving gut health, immunity markers, and even aspects of metabolism. MDPI

Paw Note

If we were to boil this all down for a pet owner:
  • Prebiotics aren’t live bugs, but the food that feeds the good bugs in your pet’s gut.
  • When used right, they can help with digestion, immunity, and overall well-being — especially for pets under stress, after antibiotics, or with GI problems.
  • They work best in moderation, introduced gradually, ideally as part of a balanced diet.
  • Probiotics + prebiotics together can be a one-two punch: reset + nurture.
