If you mean companies that can cover most or essentially all routine pet needs—food, treats, toys, beds, crates, litter, grooming, health products, and accessories—the U.S. leaders are fairly concentrated.

Major all-in-one pet retailers

chewy.com — Broadest online-focused assortment. It covers food, treats, toys, supplies, grooming, medications/pharmacy, and products for dogs, cats, birds, reptiles, fish, and small animals. Chewy had the highest U.S. pet-supplies e-commerce GMV in 2025, according to Statista.
petsmart.com — Large physical-store network plus online shopping, with food, supplies, grooming, training, boarding/daycare, and veterinary-related services. It is one of the two dominant U.S. specialty pet retailers by store scale.
petco.com — Similar full-service model: food, supplies, grooming, veterinary services, training, and products across dogs, cats, small animals, reptiles, fish, and other pets. It ranks among the leading U.S. pet-care retailers.
petsuppliesplus.com — Neighborhood-oriented pet-supply chain with food, treats, toys, litter, grooming and general supplies. It is smaller than the three above but still a significant specialty retailer.
tractorsupply.com — Particularly relevant if you have dogs, cats, chickens, horses, livestock, or other rural animals. Its pet assortment is supplemented by farm and animal-care products.
amazon.com — The broadest general e-commerce marketplace rather than a dedicated pet retailer. It has enormous pet-product selection, and Similarweb estimated Amazon at 55.3% of U.S. online pet-care retail market share for Jan–Jun 2026, versus 26.1% for Chewy.

If you're looking for a single company

For a dedicated pet-only ecosystem, the main names to investigate are Chewy, PetSmart, and Petco. Current U.S. web-traffic data puts those three at the top of the dedicated pet-food/supplies category, while other market measures also consistently identify them as major players.

If by "leading providers" you instead mean the actual manufacturers/brands behind pet essentials (e.g., Purina, Hill's, Mars, Royal Canin, KONG, etc.), that's a different list—and I can break it down by food, treats, toys, grooming, health, litter, bedding, and accessories.

How I'd segment the market

Provider	Food	Supplies	Pharmacy/health	Grooming/services	Other animals	Online
Chewy	✓	✓	✓	Limited	✓

There isn't one universally dominant provider across every dimension: current measurements vary depending on whether you're looking at online sales, web traffic, physical stores, or breadth of services. Chewy, PetSmart, and Petco are the clearest specialty “one-stop pet” competitors, while Amazon and Walmart compete through their much larger general-retail ecosystems.

If you're asking because you're evaluating companies for a pet-supplies business/marketplace, I can also break these down by annual revenue, product breadth, private-label brands, fulfillment model, customer base, and competitive advantages.

If by “all pet essentials” you mean companies that cover the broadest range of pet needs—food, treats, litter, toys, beds, grooming, health products, medications, and accessories—the leaders fall into two groups: full-line retailers and major pet-care manufacturers.

Leading all-in-one pet retailers

Chewy — Probably the strongest U.S. all-in-one online specialist. It carries food, treats, medications, litter, toys, grooming, beds, crates, aquatics, and other supplies. Chewy had about 21.7 million active customers and $3.33B in quarterly sales in its latest reported quarter.
Petco — Broad omnichannel offering spanning food, supplies, grooming, veterinary services, training, and other pet-care services.
PetSmart — One of the largest U.S. specialty pet retailers, with food, supplies, grooming, boarding/training and other services. PetSmart and Petco together represented nearly a third of the U.S. pet-store market by revenue in 2024.
Amazon — The broadest general retailer for pet products; particularly strong for accessories, consumables, household pet supplies, and third-party brands. It led U.S. online pet-care retail in H1 2026 in Similarweb's analysis.
Walmart — Very broad pet-food and basic-supplies selection, generally competing heavily on price.

Leading pet-care manufacturers

Mars Petcare — One of the two giants of global pet nutrition, with brands including Royal Canin, Pedigree, Whiskas, Sheba, IAMS, Eukanuba, Greenies and others.

If you're looking for the strongest “one-stop shop”

I'd rank them roughly:

Company	Food	Supplies	Health/meds	Services	Overall breadth
Chewy	★★★★★	★★★★★	★★★★★	★★★	★★★★★

Bottom line: If you're asking which companies are best positioned to provide essentially everything a pet owner needs, Chewy, Petco, and PetSmart are the clearest U.S. all-in-one specialists. If you're asking about manufacturers with the broadest pet-food/health portfolios, Mars Petcare and Nestlé Purina are the dominant global players. Current industry data puts Mars and Purina at the top of pet food, with Hill's a major third player.

If you're asking this from an investment/business-market perspective, I can also rank the top 10 companies by revenue, market share, product breadth, and growth potential.
