Pet Postbiotics Supplement Market

How big is the Pet Postbiotics Supplement Market in 2026?

The Pet Postbiotics Supplement Market is projected to reach USD 510.0 million by 2036, growing at a 6.9% CAGR from 2026 to 2036. FMI estimates the market at USD 261.7 million in 2026. The market was valued at USD 244.8 million in 2025. Pet ownership is stable or rising in the main economies, and owners spend more per animal on health products. Germany had 33.4 million dogs, cats, small mammals and ornamental birds in homes in 2025. Chinese urban dog and cat spending rose 7.5% in 2024. Postbiotics are a young category inside the wider pet biotics group. Trade press describes their use spreading beyond digestive health. Growth therefore depends on clinical proof and on how well brands explain the benefit to owners and vets.

Supplement adoption sets the ceiling for postbiotics more than pet numbers do. APPA reports that 53% of US dog owners and 34% of US cat owners give vitamins or supplements. Gut health is a stated concern for 17% of dog owners and 16% of cat owners. That Innova survey covered five countries, including the UK, Germany and the United States. Probiotics already serve this need, since 40% of owners who give supplements choose them. Postbiotics featured in fewer than 5% of 2025 pet food launches with digestive claims. Volume therefore depends on converting probiotic buyers more than on recruiting new users.

Key Market Trends & Insights

• Postbiotic claims are moving beyond gut health into oral care. Dinovite launched dental chews built on a postbiotic in January 2026. Other Half Pet launched a dental powder with a fermentation-derived postbiotic in 2025. Gut remains the core use, but these claims widen the buyer base.
• Veterinary brands are building gut programmes around the microbiome. Virbac introduced Floragest soft chews to French veterinarians on 2 September 2026. Each chew pairs two prebiotics with two postbiotics, yeast cell-wall extracts and an inactivated Lactobacillus helveticus strain. The product is positioned as an alternative to live probiotics, which the maker calls fragile.
• Evidence is still thin and mostly supplier-reported. The 28-day study behind the Floragest launch covered 57 dogs and 57 cats without a control group. The supplier funded the study. The dental chew claims rest on ingredient-level and laboratory studies. Brands that publish controlled trials in dogs and cats will separate from those relying on general gut claims.

Regional Highlights

• In Europe, pet populations are large but retail spending on accessories is soft. FEDIAF counted about 139 million European households with a pet, or 49% of all households. German accessory sales declined in 2025, so suppliers there compete for a fixed wallet.
• In Asia Pacific, markets diverge. Japan's cat count fell in the 2025 survey. China's urban dog and cat spending rose 7.5% in 2024. India's pet population grew from 28.4 million in 2020 to 39.2 million in 2025.

Analyst Perspective

“Pet postbiotic supplements sell on gut comfort, and owners buy them after a vet or a retailer explains the benefit. Suppliers with published trial results and veterinary channel access can hold prices, while generic gut products compete with cheaper probiotics. The main risk is proof: claims that are not backed by trials in dogs and cats limit repeat purchase.”

Why do Dogs lead by Pet Type in the Pet Postbiotics Supplement Market in 2026?

Dogs hold 55.0% of the Pet Postbiotics Supplement Market by pet type in 2026.

Dog owners spend more per animal than cat owners in Japan. Both dental launches target dogs only. Cats and other pets hold the remaining 45.0%. Cat spending in China rose 10.7% in 2024 against 4.6% for dogs. Germany has 15.7 million cats against 10.0 million dogs. Japan has 8.85 million cats against 6.82 million dogs. Cat demand therefore supports a second segment. Of the postbiotic products profiled here, only Floragest has a cat version.

Why does Powder lead by Form in the Pet Postbiotics Supplement Market in 2026?

Powder holds 48.0% of the Pet Postbiotics Supplement Market by form in 2026.

Powder goes on food, so one daily scoop can be matched to dog weight. Dinovite sells its dental powder in three sizes by dog weight. Other Half Pet also chose a bacon-flavored powder for its postbiotic dental product. Chews, tablets, capsules and liquids hold the remaining 52.0%. Chews gain where a postbiotic is paired with another claim, as in the dental chews. Floragest is a soft chew given once a day for 30 days. The supplier reports that 94% of dogs and 91% of cats accepted it.

Why does Digestive Health lead by Application in the Pet Postbiotics Supplement Market in 2026?

Digestive health holds 46.0% of the Pet Postbiotics Supplement Market by application in 2026.

Floragest launch material cites UK primary-care studies. It ranks digestive disorders third among consultation reasons in dogs and fourth in cats. That gives gut products a clear clinical use. Immunity, skin, oral health and other uses hold the remaining 54.0% combined. Oral care is a recent addition, with postbiotic dental products already on sale. Each of these claims is smaller than gut care today and no single one matches its share.

Why does Store-based Retail lead by Sales Channel in the Pet Postbiotics Supplement Market in 2026?

Store-based retail, including veterinary clinics, pet specialty stores and supermarkets, holds 52.0% of the Pet Postbiotics Supplement Market by sales channel in 2026.

Postbiotics need explanation, so the veterinary channel matters. Virbac promotes Floragest to veterinarians through its sales representatives. Online retail holds the remaining 48.0%. One dental powder offers subscription ordering every 30, 60, 90 or 120 days. Trade coverage of the German 2025 market points to weakness in physical retail.

What are the key drivers, restraints and opportunities?

Driver

Pet owners spend more per animal on health. Spending per pet is high and rising in large markets. Chinese urban dog and cat owners spent 300.2 billion yuan in 2024, up 7.5%. Japanese dog owners also spend heavily each year, so health and wellness products capture part of this extra spend.

Gut health programmes in the veterinary channel. Floragest launch material reports that 90% of veterinarians use biotics as a routine therapy. Postbiotic supplements can sit alongside existing gut programmes.

Restraint

Limited clinical evidence for postbiotics. Most evidence for postbiotic supplements in pets is supplier-reported. Probiotics have a longer record. Purina calls FortiFlora the number one veterinarian-recommended probiotic brand, so owners may choose the better-known option.

Weak spending on accessories and physical retail. German pet accessory sales fell 4.6% in 2025 and physical retail is under pressure. Japan's shrinking cat population also limits unit growth there. Suppliers cannot count on volume growth in mature markets.

Opportunity

New claims beyond the gut. Oral care claims widen the use of postbiotics. A dental product reaches owners whose dogs have no gut problem.

Growing owner bases in China and India. China's urban dog and cat spending rose 7.5% in 2024. India's pet population is forecast to reach 51.8 million in 2030, up from 39.2 million in 2025. Early supplement categories in both markets reward brands that build veterinary relationships first.

India

India is the fastest-growing profiled market from a small base. Its retail pet food sales reached USD 769.7 million in 2025. That is 0.5% of global sales and the 29th largest market. Postbiotics are a niche inside the wider pet supplement market. A 10.0% CAGR for 2026 to 2036 reflects a low starting point and fast category formation, not broad supplement growth.

Low ownership penetration, not high spending per pet, explains the lead. Only 8.2% of Indian households owned a dog in 2025, and 0.6% owned a cat. The pet population is forecast to rise 5.7% a year to 51.8 million in 2030. China's pet population is forecast to stay near 430 million over the same period. Category growth in India therefore comes from new owners, whereas China and Japan depend more on spending per pet.

Cats and online sales add two further sources of growth. The cat population rose 13.6% a year from 2.4 million in 2020 to 4.5 million in 2025. E-commerce holds 31.6% of pet food sales and has grown 31.7% a year since 2020. Online listings therefore give a new supplement category national reach faster than clinics, which hold 13.5%. Pet shops and superstores still hold 42.6%, so a launch needs shop distribution as well as online listings. India also imports more pet food than it exports, with a 2025 deficit of CAD 82.6 million.

China

China's urban dog and cat market reached 300.2 billion yuan in 2024, with cat spending rising faster than dog spending. Per-pet spending is rising as owners trade into health products. A 9.0% CAGR for 2026 to 2036 allows for price competition in a young supplement category.

Cat growth and digestive demand explain the second place. Urban dogs and cats numbered 126 million in 2025, of which 72.89 million were cats. Cat consumption rose 5.2% to 152.0 billion yuan, against 3.2% for dogs. Owners rank digestive health as the top functional concern, at 68.9% for dogs and 69.2% for cats. Gastroenteritis accounted for 6.9% of dog hospital visits and 7.8% of cat visits.

Spending per pet matters more than pet numbers. Urban pet numbers grew 1.8% in 2025, while consumption grew 4.1% to 312.6 billion yuan. Spending per dog rose 1.5% to 3,006 yuan and per cat 3.2% to 2,085 yuan. Dog households fell from 16.7% to 14.2% between 2021 and 2025, and cat households rose from 14.8% to 15.1%. Retail e-commerce now supplies about two thirds of pet food sales. Postbiotic suppliers must therefore gain share from a wallet that grew only 4.1% in 2025. Cat owners rank digestive health first at 69.2%, and both dental launches target dogs only. Gut products therefore have the clearer path to the faster-growing cat segment.

United States

The United States is a mature market for pet supplements. APPA's 2025 report finds that 53% of US dog owners and 34% of US cat owners give vitamins or supplements. A 6.0% CAGR for 2026 to 2036 reflects that maturity, so postbiotics must win share from established products.

Adoption is already high, so growth depends on new claims, not new users. Joint health, multivitamin and skin and coat products lead among dogs, so gut care sits outside the top three. Among cats, multivitamins lead, followed by pre- and probiotic and digestion products. Pre- and probiotic diets were bought by 13% of dog owners and 12% of cat owners. Those shares are 18% and 9% lower than in 2023.

Industry growth sets the benchmark. Spending reached USD 158 billion in 2025, up 3.7%. APPA projects 4.4% growth for 2026, of which about 2 points is inflation. Owners are shifting budgets from discretionary items toward essential care. A 6.0% postbiotic CAGR therefore requires share gains from established gut products, since real industry growth is near 2.4%. The United States adds owners from a large base, with 71 million dog households and 53 million cat households. With 22% of owners spending less in 2025, a postbiotic needs a stated clinical claim to keep its place.

Germany

Pets live in 43% of German households, and the pet market reached nearly EUR 7 billion in 2025. Cats live in 24% of households and dogs in one in five. A 5.6% CAGR for 2026 to 2036 reflects a large, stable owner base with cautious spending.

Flat spending, not weak ownership, limits growth in Germany. Pet food sales reached EUR 4.3 billion in 2025, up only 0.3%, while stationary retail sales fell 0.7%. Cat food leads the food segments at EUR 2.3 billion, up 1.3%. Dog food overall earned about EUR 1.8 billion, down 0.3%. Staple dog food declined, with wet dog food down 1.9% and dry dog food down 2.7%. Treats grew instead, with dog snacks up 2.1% to EUR 768 million and cat snacks up 3.0%. Chew-based postbiotic claims sit in the treat format, which is the growing part of dog food.

Channel structure separates Germany from the faster markets. Grocery retail, including drugstores and discounters, delivered 66% of pet food sales in 2025. Online sales passed EUR 1.5 billion, up 0.6% on 2024, and 61% of owners spend both in stores and online. A supplement that needs explanation therefore has to reach owners in both channels. Germany ranks first among pet food importers, at CAD 4.5 billion in 2025 and up 14.8% a year since 2020.

Japan

Japan's cat count is falling, from 9.155 million to 8.85 million in the 2025 survey. Owners spent an average of 192,356 yen per dog and 119,972 yen per cat in the 2025 survey. That spending supports value growth. A 4.8% CAGR for 2026 to 2036 is the lowest of the profiled countries and reflects flat pet numbers.

Falling pet numbers cap volume. Japan's pet population fell from 15.951 million in 2024 to 15.667 million in 2025, a decline of 1.8%. Cats fell 3.4% to 8.847 million, while dogs rose to 6.82 million. Ownership is shifting toward singles aged 20 to 39, parents of young children and households earning 9 million yen or more. Retail pet food sales declined 0.5% a year from 2019 to 2023. Japan ranked ninth among global pet food markets, at USD 4.2 billion in 2023.

Value growth has to come from mix. Agriculture and Agri-Food Canada forecasts pet food sales rising 4.6% a year to USD 5.3 billion by 2028. A 4.8% postbiotic CAGR therefore tracks the wider category, so the segment gains little share. Offline retail held 70.9% of Japanese pet food sales in 2023. E-commerce held 23.1% after the fastest growth of any channel. Shelf space and store staff therefore decide most trial purchases, unlike in China, where about two thirds of sales are online.

Who are the notable companies in the Pet Postbiotics Supplement Market?

Notable companies in the Pet Postbiotics Supplement Market include Virbac, Dinovite and Other Half Pet.

Pet postbiotic suppliers differ by their inactivated ingredient, the evidence published for it and the channel to owners. The ISAPP definition requires inanimate microorganisms or their components that confer a health benefit on the host. Live probiotics and purified metabolites alone fall outside it.

Virbac introduced Floragest to French veterinarians on 2 September 2026. The soft chew pairs two prebiotics, baobab pulp and acacia gum, with two postbiotics. The postbiotics are yeast cell-wall extracts and inactivated Lactobacillus helveticus HA-122. The chew is given once daily for 30 days and comes in four sizes, one for cats and three for dogs. The company promotes it through its sales representatives. Its published study ran 28 days in 57 dogs and 57 cats without a control group, and Virbac funded it.

Dinovite launched Triple Action Dental Chews on 7 January 2026, its first entry in dog dental care. The chews contain a postbiotic that the company describes as clinically studied. Its claims rest on ingredient-level and laboratory studies, including an average 85% reduction in odor-causing compounds. The company also sells a scoopable dental powder with a canine oral health postbiotic, in three sizes by dog weight.

Other Half Pet lists Doggie Dental, a bacon-flavored daily powder built on a precision-fermented Canine Oral Health Postbiotic. The listing, dated 9 May 2025, describes it as an alternative to conventional chews and sticks. Retail buyers should ask for the study behind the oral health claim before listing.

Purina Pro Plan Veterinary Supplements launched the FortiFlora Diarrhea Response Kit on 10 August 2026. The kit pairs kaolin and pectin stick packs with FortiFlora sachets that contain live Enterococcus lactis SF68, a probiotic. It is a gut-health comparison for clinics, not a postbiotic product, and falls outside the scope of this report.

Key Developments in the Pet Postbiotics Supplement Market

• On 2 September 2026 Virbac introduced Floragest soft chews, with two prebiotics and two postbiotics, to French veterinarians. The launch places a postbiotic gut supplement in the veterinary channel.
• On 7 January 2026 Dinovite launched Triple Action Dental Chews built on a postbiotic. The launch extends postbiotic claims from gut care to oral care in a chew format.
