The global pet supplements market is one of the fastest-growing segments in the pet care industry.

What Is Driving Pet Supplements Market Growth?

You have to understand what is driving this market because that tells you more than just the size of the opportunity. 

It tells you why the market can grow, what makes it durable, and where to focus your brand strategy.

Pet humanization 

Millennials account for roughly 33% of total pet ownership globally, according to the American Pet Products Association. More than 75% of Gen Z and millennial households own more than one pet. 

These consumers are not just buying pet food. They are reading ingredient labels, looking for veterinary guidance online, and spending on preventive care the same way they spend on their own health. That behavioural change is increasing the growth in the pet supplements market.

Preventive health 

Previously, when a pet gets sick, and the owner goes to the vet. But that’s not the case anymore. 

Pet owners now proactively support joint health, digestion, immunity, skin and coat, and emotional well-being through daily supplementation. 

This is very similar to recent human supplement and wellness trends. Pet parents are no longer waiting for a problem to appear. They are trying to prevent it using supplements.

The aging pet population

Pets are living longer due to improved nutrition and veterinary care. As they age, joint degeneration, digestive disorders, cognitive decline, and immune issues become more common. 

This creates demand for hip and joint supplements, probiotics, and immune-support formulas. These are ongoing, daily-use products. 

For ecommerce brands, that means you should include subscriptions to your pricing structure.

Rising pet ownership 

North America is currently dominating the pet supplements market share. But the fastest growth is happening in Asia Pacific. 

Pet humanization trends are growing rapidly across China, Japan, South Korea, Australia, and India. Latin America, the Middle East, and Africa are also showing early-stage growth due to increasing urbanization and disposable incomes.

Digital channels 

Pet owners research online before they buy. Veterinary advice gotten through social media, peer reviews, influencer content, and educational articles is all affecting purchase decisions. 

This is an advantage for DTC ecommerce brands that invest in content marketing, SEO, and TikTok Shop.

The pandemic

Pet adoption increased during COVID-19. Online pet product purchasing tripled over five years, from 8% in 2015 to 30% by 2020, according to the American Veterinary Medical Association. 

That change has continued until now. Pet supplements ecommerce growth is not something that started and stopped with the pandemic. 

Pet Supplements Market Segmentation

The pet supplement industry is divided into 3 segmentations. You have to understand these segmentations if you want to scale your business.

By Pet Type

The dog supplements market is the largest segment in the industry. Dogs accounted for 63.1% of the global pet supplements market share in 2025, according to Grand View Research. 

Approximately 68 to 69 million US households own at least one dog. Dog owners also tend to spend more on health and wellness products per pet. 

Also, dogs are more physically active and more prone to joint and mobility issues as they age, which means more consistent demand for supplements.

The cat supplements market is smaller but growing faster. Cat supplements are projected to reach a CAGR of 7.2% in 2033. This is being caused by increasing cat ownership, especially among younger urban consumers. 

Indoor and aging cats face specific health challenges, like digestive sensitivity, hairballs, urinary tract issues, joint stiffness, and skin and coat conditions. These diseases increase the demand for cat supplement formulas.

By Form

Chewables had 69.8% of the global pet supplements market share by form in 2025. The reason is that chewables are easy to administer, palatable for most dogs and cats, and absorbed effectively during digestion. 

Most pet owners find chewables far easier to give their pets than tablets or capsules. For brands, chewables also signal a certain level of quality. They look and feel like a bone treat.

Powdered supplements are the fastest-growing form, with a projected CAGR of 7.1% by 2033. Powders have faster absorption than tablets, they mix easily into existing food, and allow for flexible dosing. They suit multi-ingredient formulas that combine several functional benefits into a single daily serving. 

The format is becoming popular among pet owners who prefer a less-processed, more food-like supplement option.

By Application

Hip and joint supplements are the largest application category, holding 21.56% of the global pet supplements market share in 2025. Joint pain and mobility issues are among the most visible health concerns in aging dogs and cats. 

These concerns are being solved by glucosamine, chondroitin, and omega-3 fatty acids. These drugs have high repeat purchase rates and subscription potential because joint support is an ongoing daily need.

Digestive health supplements are expected to grow at a CAGR of 6.3% by 2033. Digestive issues are among the most commonly reported health concerns in both dogs and cats. Probiotics, prebiotics, digestive enzymes, and fibre blends have all increased in demand due to this. 

Other high-growth pet supplement categories include calming and anxiety supplements, immune support, skin and coat health, and cognitive function. 

By Supplement Type

Glucosamine holds the largest share of the supplement type market at 37.24% in 2026. It is one of the most recognized and trusted supplement ingredients among pet owners and veterinarians.

Probiotics and prebiotics are the fastest-growing supplement type in the pet supplements industry. Increasing awareness of the gut-immune connection and the cultural trend toward digestive health are promoting demand. 

By Distribution Channel

Offline channels accounted for 76.5% of pet supplements market share by distribution in 2025. Veterinary clinics, pet specialty stores, hypermarkets, and pharmacies all benefit from professional guidance and the trust that comes with in-person recommendations.

But the main growth is online. Pet supplements ecommerce growth is projected at a CAGR of 9.0% by 2033. That is the fastest of any distribution segment. The reason for this is because online channels:

• Remove shelf space constraints

• Enable subscription purchasing

• Allow detailed ingredient education that physical retail cannot provide

They also reach consumers in the exact moments they are researching pet health topics.

FAQs

1. Are pet supplements regulated?

Yes, but the rules are not as strict as they are for human supplements or prescription medications. In the United States, the FDA oversees pet food and supplements under the Federal Food, Drug, and Cosmetic Act. 

Pet supplements need to be safe and properly labelled, but brands do not need government approval before selling them. That makes it easier to launch new products. But it also means the brand is fully responsible for making sure the product is safe and accurately described. 

Many reputable brands join the National Animal Supplement Council, which runs a voluntary quality seal program to show consumers they meet higher standards. In Canada, the Canadian Food Inspection Agency oversees pet supplements. In Europe, the rules differ by country.
