Potato Fibre – Functional Ingredient for Dog Microbiome and Gut Health
Summary
Potato fibre is one of those ingredients that rarely makes headlines — yet it quietly underpins some of the most important functions in a well-designed supplement. In Bonza’s Bioactive Bites supplement range, potato fibre is included at 8.00% in Bounce (joint support) and 7.00% in Boost (complete nutrition), serving a dual role in both: it functions as a natural binding agent that gives each chewy bite its structure and texture, while simultaneously contributing genuine prebiotic and fermentative benefits to your dog’s gut.
Unlike purified, single-component fibres such as cellulose or inulin, potato fibre is a naturally complex matrix containing multiple fibre types — cellulose, hemicellulose, pectin and resistant starch — each fermented at different rates by different bacterial populations in the hindgut. This multi-component profile means potato fibre delivers sustained, graduated fermentation rather than the rapid gas production sometimes associated with highly soluble fibres, making it particularly well-suited to sensitive digestive systems.
What makes potato fibre especially interesting from a canine nutrition perspective is that it has been directly studied in dogs — not just extrapolated from human or rodent models. A pair of landmark canine studies from the University of Illinois demonstrated that dietary potato fibre produces dose-dependent increases in all three major short-chain fatty acids (acetate, propionate and butyrate), selectively enriches Faecalibacterium populations, and achieves all of this without compromising nutrient digestibility or stool quality.¹˒²
In this article, we examine the evidence behind potato fibre’s composition, its mechanisms of action in the canine gut, and why it earns its place in both Bounce and Boost — not just as a functional excipient, but as a genuine contributor to gut health and whole-body wellness.

Key Takeaways
- Canine-researched prebiotic fibre. Potato fibre has been directly studied in dogs, with results demonstrating linear increases in all individual and total short-chain fatty acids (acetate, propionate and butyrate) alongside decreased faecal pH — hallmarks of beneficial colonic fermentation.¹
- Selectively enriches beneficial bacteria. Canine microbiome analysis showed that increasing dietary potato fibre significantly increased faecal proportions of Faecalibacterium — one of the most important butyrate-producing genera in the gut — while increasing the Firmicutes-to-Fusobacteria ratio.²
- Multi-component fibre matrix. Potato fibre contains approximately 55–65% total dietary fibre comprising cellulose, hemicellulose, pectin and resistant starch, providing graduated fermentation across different regions of the hindgut rather than rapid, localised gas production.¹˒⁴
- No negative impact on nutrient digestibility. Canine feeding trials showed no differences in apparent total tract digestibility of dry matter, organic matter, crude protein, fat or energy at inclusion rates up to 6%, with total dietary fibre digestibility actually increasing linearly.¹
- Protects probiotic survival. In vitro research demonstrated that potato fibre significantly improved the gastric survival of multiple Lactobacillus strains — a finding directly relevant to the co-formulation with Lactobacillus helveticus HA-122 in both Bounce and Boost.⁴
- Dual functional role in Bounce and Boost. At 8.00% and 7.00% inclusion respectively, potato fibre contributes both prebiotic gut health benefits and natural binding, texture and moisture management properties — meaning every functional contribution to the chewy bite format simultaneously supports digestive wellness.
What Is Potato Fibre?
Potato fibre is a co-product of potato starch manufacturing — the fibrous cell wall material that remains after starch has been extracted from potato tubers (Solanum tuberosum). Rather than being a single, purified fibre compound, it retains the complete structural matrix of the potato cell wall, making it a naturally complex fibre source with multiple functional fractions.
Compositional analysis from canine feeding trials shows potato fibre typically contains approximately 55% total dietary fibre, 29% starch (including both digestible and resistant fractions), 4% crude protein and 2% fat.¹ Commercial potato fibre products report even higher fibre content — up to 65% total dietary fibre comprising pectin, cellulose and hemicellulose, with the starch fraction split between approximately 12% digestible starch and 8% resistant starch.⁴
This multi-component nature is central to potato fibre’s value. Where purified fibres deliver a single fermentation profile, the intact potato cell wall matrix offers a spectrum of fibre types with differing solubilities, fermentation rates and bacterial substrate preferences. The cellulose and hemicellulose fractions provide insoluble bulk and slower fermentation, while the pectin and resistant starch fractions deliver more readily fermentable substrates that fuel SCFA production in the proximal colon.
In the context of supplement formulation, potato fibre’s exceptional water-binding capacity — it can hold up to twelve times its own weight in water — makes it a valuable natural excipient for managing texture, cohesion and moisture in soft chew formats.⁴ This means it serves a genuine dual purpose: structural functionality and nutritional contribution are delivered by the same ingredient.
Bioactive Compounds and Fibre Fractions
Potato fibre’s health benefits stem from its four principal fibre fractions, each contributing distinct mechanisms of action in the gut:
Cellulose forms the backbone of the potato cell wall — a linear polymer of β-1,4-linked glucose units that resists mammalian digestive enzymes. In the hindgut, cellulose provides insoluble bulk that supports healthy intestinal transit, stool formation and mechanical stimulation of the gut wall. It is slowly and only partially fermented by colonic bacteria, providing sustained substrate availability deep into the distal colon.
Hemicellulose is a heterogeneous group of branched polysaccharides (including xyloglucans and galactans) that sit between cellulose microfibrils in the cell wall. Hemicelluloses are more readily fermented than cellulose, providing intermediate-rate substrates that bridge the fermentation gap between rapidly soluble and slowly insoluble fractions. Neutral sugar analysis of potato fibre reveals significant galactose (14.8%), arabinose (11.8%) and xylose (9.6%) content — common hemicellulose and pectin constituents — confirming this fraction’s contribution to microbial fermentation.⁴
Pectin is a highly branched polysaccharide rich in galacturonic acid that acts as the “cement” holding plant cell walls together. Pectin is the most rapidly fermented fraction of potato fibre, serving as a preferred substrate for beneficial bacterial populations and contributing to early-phase SCFA production. Research has confirmed that pectin fractions within potato fibre support increased microbial diversity, with specific increases in genera including Lachnospira, Butyrivibrio and Parabacteroides.⁴
Resistant starch — the starch fraction within potato fibre that escapes enzymatic digestion in the small intestine — reaches the colon intact and is fermented by specialist bacteria. Potato-derived resistant starch is classified as Type 2 (RS2), characterised by its granular structure that limits amylolytic enzyme access. This fraction is a particularly efficient substrate for butyrate production via the acetyl-CoA pathway, engaging key butyrate-producing taxa including Faecalibacterium and Eubacterium.
The collective effect of these four fractions is graduated fermentation — different fibre components are utilised by different bacterial populations at different rates and in different regions of the hindgut. This means potato fibre avoids the “fermentation spike” associated with rapidly fermentable single-component fibres (such as purified inulin at high doses), instead providing sustained SCFA production from the proximal to the distal colon.
Evidence-Based Health Benefits for Dogs
Short-chain fatty acid production
The most robust evidence for potato fibre’s benefits in dogs comes from a controlled feeding trial at the University of Illinois, in which ten adult dogs received graded concentrations of potato fibre (0%, 1.5%, 3%, 4.5% and 6%) in a replicated Latin square design.¹
The results were unambiguous: linear increases were observed for all individual short-chain fatty acids — acetate, propionate and butyrate — as well as total SCFA concentrations, with a concomitant linear decrease in faecal pH. These dose-dependent responses indicate that potato fibre is a genuinely fermentable substrate in the canine hindgut, and that its fermentation products increase proportionally with dietary inclusion.¹
This SCFA profile matters because each fatty acid serves distinct physiological functions. Butyrate is the primary energy source for colonocytes (the cells lining the colon), supports epithelial cell proliferation and differentiation, strengthens barrier function and has established anti-inflammatory properties.² Propionate is largely taken up by the liver where it participates in gluconeogenesis and cholesterol metabolism. Acetate enters systemic circulation and contributes to peripheral energy metabolism.
Nutrient digestibility preservation
A common concern with dietary fibre supplementation is the potential to reduce nutrient absorption. The same canine study directly addressed this, finding no differences in apparent total tract digestibility of dry matter, organic matter, crude protein, acid-hydrolysed fat or energy across all potato fibre inclusion levels up to 6%.¹
Notably, total dietary fibre digestibility actually exhibited a linear increase with increasing potato fibre concentrations, indicating that the fibre itself was being effectively fermented without displacing the digestion of other nutrients.¹ This is a particularly important finding for a supplement context where every ingredient must contribute without compromising the nutritional integrity of the dog’s overall diet.
Stool quality maintenance
The trial also confirmed that faecal scores remained within acceptable ranges across all inclusion levels, and faecal protein catabolite concentrations (markers of potentially harmful protein fermentation) were low or undetectable — with the exception of spermidine, which increased linearly.¹ The low protein catabolite profile suggests that potato fibre effectively redirects colonic microbial metabolism away from proteolytic fermentation (which produces potentially harmful compounds such as ammonia, phenols and indoles) and toward saccharolytic fermentation (which produces beneficial SCFAs).
Anti-inflammatory potential
Translational research from the same laboratory demonstrated that potato fibre attenuated signs and inflammation associated with experimental colitis in a mouse model. Mice fed a potato fibre-supplemented diet showed reduced markers of intestinal inflammation compared to controls, with the authors attributing these effects to the SCFA production — particularly butyrate — generated by potato fibre fermentation.³
While this study was conducted in mice rather than dogs, the mechanism is directly relevant: the SCFA-mediated anti-inflammatory pathway operates through conserved mammalian mechanisms including histone deacetylase inhibition, NF-κB modulation and G-protein coupled receptor activation that are shared across species.
Gut Health and the Microbiome Connection
Microbiome modulation in dogs
The second part of the Illinois research programme used 16S rRNA gene pyrosequencing to map the precise microbiome changes induced by dietary potato fibre in dogs.² The results revealed meaningful shifts in microbial community structure:
At the phylum level, increasing potato fibre concentrations produced a significant increase in Firmicutes proportions alongside a significant decrease in Fusobacteria. This shift is consistent with a beneficial fermentation profile — Firmicutes diversity is associated with reduced risk of hindgut diseases and reflects a diet rich in fermentable carbohydrates.²
At the genus level, the most striking finding was a significant increase in faecal proportions of Faecalibacterium with increasing dietary potato fibre.² Faecalibacterium prausnitzii is widely recognised as one of the most important commensal bacteria in the mammalian gut — a primary butyrate producer whose depletion is consistently associated with inflammatory bowel disease, dysbiosis and compromised barrier function in both humans and companion animals.
Post hoc correlation analysis revealed positive associations between Bifidobacterium spp. and butyrate production, and between Lactobacillus spp. concentrations and potato fibre intake, although qPCR confirmation showed that the primary enrichment was in Faecalibacterium rather than in Lactobacillus or Bifidobacterium directly.² This distinction is important — it identifies Faecalibacterium enrichment as the primary mechanism through which potato fibre enhances butyrate production in the canine gut.
Probiotic protection: synergy with Lactobacillus helveticus HA-122
A particularly relevant finding for both Bounce and Boost comes from research demonstrating that potato fibre significantly improved the survival of multiple Lactobacillus strains — including L. rhamnosus LGG and L. fermentum PCC — under simulated gastric conditions.⁴ The fibre matrix appears to provide a physical protective effect, buffering probiotic bacteria against the acidic environment of the stomach and improving their viability as they transit to the colon.
This is directly relevant to both Bounce and Boost, which co-formulate potato fibre alongside Lactobacillus helveticus HA-122. While specific survival data for L. helveticus HA-122 with potato fibre has not been published, the demonstrated protective mechanism across multiple Lactobacillus species strongly supports a synergistic relationship between these two ingredients — the fibre matrix potentially enhancing probiotic delivery while the probiotic contributes to the fermentation environment that utilises the fibre.
Colonic barrier function
Translational research has demonstrated that potato fibre and potato-derived resistant starch upregulate genes involved in colonic barrier function — including those encoding mucin proteins and tight junction components — in animals fed high-protein diets.⁵˒⁶ Rats receiving potato fibre showed increased goblet cell numbers per crypt and longer colonic crypts compared to cellulose controls, alongside beneficial shifts in SCFA concentrations and reduced concentrations of potentially harmful protein catabolites including phenol and p-cresol.⁵
These findings connect directly to Bonza’s “The Dog Gut Microbiome – Vital Key To Dog Health” framework — the microbiome modulation achieved by potato fibre translates into functional improvements in barrier integrity, inflammatory tone and metabolic output that influence health far beyond the digestive tract.
One Gut. Whole Dog.
Potato fibre’s evidence profile aligns with the gut–immune axis through its butyrate-mediated support of barrier integrity and colonocyte health. Butyrate directly strengthens the intestinal epithelial barrier by fuelling colonocyte metabolism, promoting tight junction assembly and modulating local immune responses in the gut-associated lymphoid tissue (GALT).² When barrier integrity is maintained, the translocation of bacterial endotoxins and inflammatory triggers into systemic circulation is reduced — supporting balanced immune function throughout the body.
The gut–joint axis is particularly relevant to potato fibre’s inclusion in Bounce. Emerging research recognises that gut-derived inflammatory mediators — including lipopolysaccharides (LPS) from gram-negative bacteria — can translocate across a compromised intestinal barrier and contribute to systemic low-grade inflammation that exacerbates joint conditions. By producing butyrate that strengthens barrier integrity and by redirecting microbial metabolism away from proteolytic pathways that generate pro-inflammatory catabolites, potato fibre supports the gut environment that helps keep systemic inflammatory signalling in check. This positions potato fibre as a meaningful complement to Bounce’s direct-acting joint support ingredients — glucosamine HCl, chondroitin sulphate, MSM, hyaluronic acid and the botanical anti-inflammatory complex — by addressing the inflammatory contributions that originate in the gut.
The reduction in proteolytic fermentation markers (phenols, p-cresol) demonstrated in potato fibre research also has implications for the gut–liver axis, as these compounds would otherwise require hepatic detoxification after absorption from the colon.⁵ By redirecting microbial metabolism toward saccharolytic pathways, potato fibre reduces the metabolic burden on the liver — a connection that, while not yet demonstrated directly in canine potato fibre studies, follows established physiological pathways.
How Potato Fibre Compares to Other Fibre Sources
Understanding where potato fibre sits in the fibre spectrum helps explain why it is particularly well-suited to supplement formulation:
Compared to inulin (chicory root fibre): Inulin is a highly soluble, rapidly fermentable fructan that produces robust SCFA responses but can cause osmotic diarrhoea and excessive gas production at higher inclusion levels. Potato fibre is moderately fermentable with a mixed soluble-insoluble profile, producing sustained but gentler fermentation that is better tolerated at higher inclusion rates.¹ The two fibres are complementary — Boost also contains chicory root powder (0.08%) to provide the rapidly fermentable fructan fraction alongside potato fibre’s more graduated profile, while Bounce pairs potato fibre with Fibrofos® 60 (FOS) for a similar complementary fermentation strategy.
Compared to beet pulp: Beet pulp is the most widely used fibre in commercial dog foods, valued for its balance of soluble and insoluble fractions. Both beet pulp and potato fibre increase Firmicutes and decrease Fusobacteria in canine faecal microbiomes.² However, potato fibre’s multi-component matrix (including resistant starch) provides a broader substrate range for diverse bacterial populations, and its water-binding capacity makes it particularly functional in soft chew supplement formats.
Compared to cellulose: Cellulose is an insoluble, minimally fermentable fibre used primarily for faecal bulking. Compared to cellulose controls, potato fibre produces significantly higher SCFA concentrations, supports greater microbial diversity and provides prebiotic benefits that cellulose cannot deliver.¹˒⁵ In the Paturi et al. (2012) study, rats fed potato fibre showed higher colonic Bifidobacterium and Lactobacillus populations and more favourable SCFA profiles than cellulose-fed controls.⁵
Compared to psyllium: Psyllium is a viscous, gel-forming fibre often used therapeutically for constipation or diarrhoea management. While psyllium excels at water regulation and stool normalisation, it is poorly fermented and does not deliver the prebiotic or SCFA-producing benefits of potato fibre. The two fibres operate through fundamentally different mechanisms.
Why Bonza Uses Potato Fibre in Bounce and Boost
Potato fibre’s inclusion at 8.00% in Bounce and 7.00% in Boost reflects a formulation philosophy where every ingredient must earn its place through measurable contribution — and potato fibre earns it twice over.
Functional role: As a natural binding agent, potato fibre’s exceptional water-holding capacity (up to 12× its weight) contributes to the cohesion, texture and moisture stability of each chewy bite in both supplements. This structural role ensures consistent supplement delivery without relying on synthetic binders or excessive use of ingredients that serve no nutritional purpose.
Nutritional role: Simultaneously, those inclusion rates deliver genuine prebiotic and fermentative benefits. The canine research demonstrating dose-dependent SCFA increases at inclusion rates of 1.5–6% suggests that both Bounce’s 8.00% and Boost’s 7.00% inclusion — while in a supplement rather than a complete diet — provide a meaningful substrate dose for colonic fermentation with each daily serving.¹
Synergistic formulation in Boost: Potato fibre works synergistically with multiple other Boost ingredients. Its demonstrated probiotic-protective properties complement the Lactobacillus helveticus HA-122 inclusion. Its prebiotic fermentation profile works alongside chicory root powder (a rapidly fermentable fructan) and inactivated yeast (a source of mannan-oligosaccharides) to create a multi-tier prebiotic approach — different fibres feeding different bacterial populations at different rates.
Synergistic formulation in Bounce: In the joint-support context, potato fibre’s role extends beyond gut health into systemic relevance. The butyrate produced through its fermentation supports anti-inflammatory tone via the gut–joint axis — a mechanism through which intestinal barrier integrity and microbial metabolite production influence joint inflammation and comfort. This makes potato fibre a meaningful partner to Bounce’s glucosamine HCl, chondroitin sulphate, MSM and botanical anti-inflammatory complex, supporting the structural repair ingredients from the inside out through reduced systemic inflammatory signalling. Potato fibre also complements Bounce’s Fibrofos® 60 (FOS) prebiotic inclusion, with the two fibre types providing complementary fermentation profiles — rapid (FOS) and sustained (potato fibre) — for comprehensive colonic coverage.
Plant-based integrity: As a naturally derived co-product of potato starch manufacturing, potato fibre aligns with Bonza’s commitment to plant-based, sustainable formulation. It is allergen-free, non-GMO and requires no chemical processing for its production — the fibrous cell wall material is simply retained and dried after starch extraction.
Safety, Tolerability and Dosage Considerations
Potato fibre has an excellent safety and tolerability profile in dogs. The University of Illinois feeding trial — which tested inclusion rates up to 6% in complete diets over multiple 14-day periods — reported no adverse effects on nutrient digestibility, stool quality or palatability at any inclusion level.¹
The graduated fermentation profile of potato fibre is a key contributor to this tolerability. Because its fibre fractions are fermented at different rates, there is no sudden influx of fermentable substrate to the colon that might trigger excessive gas production or osmotic effects. This makes potato fibre more digestively comfortable than equivalent doses of highly soluble, rapidly fermentable fibres.
In Bounce and Boost’s supplement format at 8.00% and 7.00% inclusion respectively within a daily chewy bite, the actual amount of potato fibre consumed per serving is modest relative to the total diet. This means it contributes beneficial fermentative substrate without risk of overconsumption, particularly when fed according to Bonza’s dosing guidelines based on body weight.
As with any fibre source, dogs transitioning to a new supplement should be introduced gradually over 5–7 days to allow the gut microbiome time to adapt to the new substrate availability.
How to Support Your Dog’s Fibre Intake
A step-by-step guide to optimising fibre balance for gut health.
- Assess your dog’s current fibre sources.
Review the ingredient list of your dog’s main diet to identify existing fibre sources — common options include beet pulp, cellulose, chicory root and various legume or grain fibres.
- Introduce fibre-containing supplements gradually.
Start with half the recommended Bounce or Boost serving for the first 5–7 days, allowing gut bacteria time to adapt to the new fermentable substrates before moving to the full daily amount.
- Monitor stool quality as a fermentation indicator.
Well-formed, consistent stools suggest balanced fermentation. Excessively soft stools may indicate too rapid an introduction, while very hard, dry stools could suggest insufficient fermentable fibre in the overall diet.
- Ensure adequate water availability.
Fermentable fibres draw water into the colon as part of the fermentation process. Always ensure fresh water is freely available, particularly in the first week of supplementation.
- Observe energy and comfort levels.
Dogs benefiting from improved colonic fermentation often show improved energy, reduced flatulence over time (as the microbiome stabilises) and consistent appetite — all indicators that fibre balance is well calibrated.
- Consult your veterinarian for dogs with existing GI conditions.
Dogs with diagnosed inflammatory bowel disease, chronic enteropathy or other gastrointestinal conditions may respond differently to fibre supplementation. Discuss any dietary changes with your vet, particularly for dogs on therapeutic diets.
Frequently Asked Questions
No. Potato starch is the purified starch extracted from potato tubers — a digestible carbohydrate that is broken down by amylase enzymes in the small intestine. Potato fibre is the cell wall material that remains after starch extraction, comprising cellulose, hemicellulose, pectin and a small residual starch fraction (including resistant starch). While potato starch is primarily an energy source, potato fibre functions as a prebiotic fermentable substrate in the colon.
Dogs cannot digest potato fibre enzymatically in the small intestine — this is precisely what makes it valuable. The fibre passes intact to the large intestine where it is fermented by resident bacteria, producing short-chain fatty acids that nourish colonocytes, modulate the microbiome and support barrier function. Canine research confirms potato fibre is moderately fermentable, meaning it is effectively utilised by hindgut bacteria without causing digestive discomfort.¹
Yes. Potato fibre is derived from potatoes, which are not grains. It is naturally gluten-free and allergen-free, making it suitable for dogs with grain sensitivities or those on grain-free diets. It contains minimal protein (approximately 4–5%), and the protein present is from the potato cell wall rather than the storage proteins typically associated with food sensitivities.
Different fibre types serve different functions. Inulin and chicory root fructans are rapidly fermented, producing quick SCFA responses but potentially causing gas and osmotic effects at higher doses. Potato fibre provides graduated, sustained fermentation across the full length of the colon. By combining complementary fibre types — potato fibre with chicory root in Boost or with FOS in Bounce — each supplement delivers multi-rate fermentation that feeds diverse bacterial populations throughout the hindgut.
Potato fibre’s moderate fermentation rate makes it less likely to cause excessive gas than highly soluble fibres. The canine feeding trial reported acceptable stool quality and low protein catabolite concentrations across all inclusion levels.¹ Most dogs tolerate potato fibre well, particularly when introduced gradually over 5–7 days.
In the context of a complete diet, canine research tested inclusion rates up to 6% with no adverse effects.¹ In Bounce and Boost’s supplement format, the 8.00% and 7.00% refer to the proportion of potato fibre within the chewy bite itself — the actual daily intake relative to the dog’s total diet is much smaller, well within the researched safe range.
