U.S. Online Pet Food and Supplies Market: Overview

The online pet food and supplies is an e-commerce platform for the pet care business. Pet food, treats, supplements, grooming products, toys, accessories, litter, health products, and other supplies for pets are bought and sold online through e-commerce.  The sale and purchase take place across a variety of channels – ecommerce websites, mobile applications, direct-to-consumer brands’ own ecommerce channels, online marketplaces, or omnichannel retailers that offer home delivery or click-and-collect in addition to traditional physical stores. The main players in the segment include pure-play online players such as Chewy, large marketplaces such as Amazon, and omnichannel pet specialty chains such as Petco and PetSmart. In pet care, the focus in recent times has been on auto-replenishment subscription models (where consumers subscribe to recurring purchases of products such as dry food or litter), a wide range of products (including premium and veterinary diets), and doorstep delivery.

U.S. Online Pet Food and Supplies Market: Dynamics

Growth Drivers

Does the rise in pet ownership drive growth in the U.S. online pet food and supplies market?

The increase in pet ownership in the United States is a key driver of the U.S. online pet food and supplies market. As more U.S. households acquire pets — most notably cats and dogs — the long-term, repeat demand for major pet consumables, including dry and wet food, treats, litter, grooming supplies, and supplements, continues to grow. Data from the American Pet Products Association (APPA) indicates that a large share of U.S. households own one or more pets, implying a large and sustainable base of recurring pet-purchase consumers.

Greater pet ownership (including younger millennials and Gen Z) leads to greater online familiarity, a higher click-to-buy proclivity, and the practice of auto-ship subscriptions for essential pet products, boosting online growth. The proliferation of digital supermarkets, online retailers, and pet-buying platforms such as Chewy and Amazon makes it easier to place repeat orders for everyday pet essentials, just as Amazon makes it easy for consumers to buy an increasingly wide range of household items. First-time pet owners look to the Internet for search, reviews, price comparisons, convenient delivery, etc., creating significant long-term demand for online purchases of pet food and other essential pet supplies.

Restraints

Intense competition from brick-and-mortar retailers acts as a significant restraint on industry growth

The intense competition from brick-and-mortar players is one of the main limitations for the growth of the U.S. online pet food and supplies market. Large players have established a proven store strategy that drives consistent traffic and a strong distribution network, both of which are vital for long-term success. Physical stores also offer the possibility of immediate purchase and physical interaction that online players lack. Large retailers can also offer additional in-store services (i.e., grooming and veterinary clinics), so consumers may choose their convenient store for other qualities. Many brick-and-mortar players have enhanced their omnichannel capabilities by adding fast delivery and BOPIS, so it is less likely that shoppers will switch exclusively to online channels.  Long-established store networks also enable retailers to negotiate terms with suppliers and offer aggressive prices, increasing price pressure.

Opportunities

Does the rising partnership offer a potential opportunity for the U.S. online pet food and supplies industry?

The growing partnership is expected to offer a potential opportunity for market development over the projected period. For instance, in October 2025, Instacart, the market leader in grocery technology in North America, announced a new partnership with Pet Supplies Plus, North America’s largest franchiser of pet stores, to offer customers same-day delivery from over 700 stores across the US in as little as an hour. Instacart customers will also be able to shop over 11,000 products from 400+ brands they know and trust at exclusive loyalty member-only prices, bringing even more convenience to homes across the country without pricing out consumers.

As part of this partnership, there will also be over 20 Wag N’ Wash stores, the up-and-coming self-wash, grooming, and natural pet food franchise that is a sister brand of Pet Supplies Plus. With this launch, Instacart is the only online marketplace to carry all five of the top US-based pet retailers.

Challenges

Why do the regulatory & compliance hurdles pose a significant challenge to the U.S. online pet food and supplies industry?

Regulatory and compliance barriers are among the largest risks to the U.S. online pet food and supplies industry, since pet food is classified as a “consumable” product and, as such, companies are required to meet product safety, labeling, and distribution requirements across multiple states and regions. Any noncompliance can lead to recalls, fines, reputation damage, and suspension of sales—all of which could directly erode revenue and stakeholder/consumed trust.

While pet food safety is regulated by the FDA, ingredient definitions and labeling standards are set by AAFCO. It is the online company's responsibility to ensure that each product meets FSMA standards and each state's unique pet food regulations. However, this can be a greater challenge for nationwide online sellers subject to multiple state-specific requirements.

By Pet Type Insights

Why do dogs hold the dominant position in the U.S. online pet food and supplies market?

The dogs segment captures the largest revenue share in 2024. The growth is driven by increased spend per pet and the continued likelihood of repeat purchases. As cited by the American Pet Products Association, most of the spend on pet care in the U. S. is for dogs, and it is generally more items, i.e., more food, more treats, more accessories, more healthcare products, etc., for dogs than for other types of pets.

By Product Type Insights

Are dry foods growing substantially in the U.S. online pet food and supplies market?

The dry foods segment dominates the market. The market growth is attributed to dry pet food's low price, extended shelf life, and the lack of a need for frequent purchases. Dry pet food, especially dry kibble for dogs and cats, is more popular than other types of food because it allows owners to pay less per portion and save on storage space. As the American Pet Products Association reports, basic diet purchases are the first top-up expense for pet owners, making dry food the main revenue source in the pet care industry. Online stores like Amazon or Chewy profit from this auto-ship cycle of dry food, as the consistent allowance for this product is more likely than not to generate a repeat purchase.
