For most pet owners, Chewy and PetSmart are the top choices due to their extensive variety of products, reliable shipping, and strong customer service. If you have specific needs—such as durable outdoor gear, natural or holistic products, or precise health and medication management—niche retailers like Ruffwear, Only Natural Pet, and PetMed Express are better specialized options.

Are you looking for supplies for a specific type of pet (like a dog, cat, or reptile), or do you need something specialized like prescription medications or organic food?
If you're shopping in the U.S., several online retailers have established reputations for broad selections of pet food, supplies, toys, and accessories. Current industry and consumer sources consistently identify Chewy, Petco, PetSmart, and Amazon as major online destinations.
Chewy — A pet-focused online retailer with a very large selection, Autoship subscriptions, pharmacy services, and food from many established brands. Recent reporting says Chewy had about 21.7 million active customers in its latest reported quarter.
Petco — Offers food, treats, toys, grooming products, supplies, and pharmacy products. Its online store also integrates with Petco's physical locations and services.
PetSmart — A large pet retailer with online ordering covering food, toys, bedding, habitats, grooming products, and other supplies. It was the most recognized online pet-supply brand in a 2024 U.S. brand-awareness survey.
Amazon — Particularly useful for comparing prices and finding a huge variety of pet products. Consumer Reports found Amazon and Chewy were among the most-used online pet stores in its survey, with high satisfaction for price and delivery.
For specialty needs, dedicated online retailers can also make sense—for example, 1800PetMeds for pet medications or niche stores for particular diets and accessories.
One important distinction: a retailer being reputable doesn't mean every product it carries is equally high-quality. For food, treats, supplements, and health products, it's worth checking the manufacturer's credentials, ingredients, veterinary guidance where appropriate, and whether the seller is an authorized source.
If you tell me whether you need dog, cat, bird, reptile, or small-animal supplies, I can narrow this down to the most useful online retailers and compare their prices/shipping.
If you’re shopping in the U.S., these are some of the better-known online pet-supply retailers:
chewy.com — Best overall. Excellent selection of food, treats, toys, litter, grooming supplies, and medications. Its Autoship program is particularly convenient for recurring food and litter purchases. Current sources continue to rank it highly for selection and convenience.

amazon.com — Best for sheer variety and convenience. Consumer Reports found high satisfaction with Amazon for price, delivery speed, and usability, though I'd pay closer attention to the individual seller when buying food, supplements, or health products.
1800petmeds.com — Best for pet medications and health products. It's a specialized online pet pharmacy rather than a general-purpose pet store.
My quick picks: Chewy for everyday shopping, Petco/PetSmart if you want store backup, Amazon for maximum variety, and 1800PetMeds for medications.
One caveat: a retailer being reputable doesn't automatically mean every product it sells is high quality—the specific food, treats, supplement, or equipment brand matters too.
