Chewy vs Petco is one of the most common comparisons pet owners make, because shoppers weighing these two online pet retailers usually compare selection, delivery speed, price and what happens when an order goes wrong. Shop and Bark sells dog apparel, toys and essential health supplies online, so we look at this comparison from the buyer's side. Because prices and promotions change often, we avoid quoting numbers here and point you to each retailer's site for current figures.
Chewy vs Petco at a Glance: How the Two Retailers Compare
Chewy and Petco both ship pet supplies to your door, but they are built around different strengths. Chewy is an online-only retailer with a food, treats and medications catalog and recurring-order options. See a direct shipping time comparison for both retailers.
Our pick depends on the shopper. If you mostly reorder the same food and want it delivered on a schedule, an online-first retailer usually fits best.
Product Selection and Brand Availability for Dogs and Cats
Selection is the first filter most shoppers apply, and it is where the two retailers differ most in ways that are easy to miss. Both carry a broad dog and cat catalog, but depth varies by category, brand and whether you shop online or in a store. The practical question is which retailer reliably stocks the specific items you buy.
Food, Treats and Specialty Products
Both retailers carry a range of food and treat brands, so check the exact brand, size and formula you buy. The differences show up in three places:
- Bag and case sizes. Stock on bag and case sizes can differ between retailers. Check the exact size before comparing price.
- Prescription and specialty diets. Verification and stock levels for therapeutic diets can vary. Confirm the exact formula is in stock before relying on it for a pet with a medical need.
- Specialty and limited-ingredient options. Freeze-dried raw, limited-ingredient and novel-protein foods may be offered, but the brand mix can shift. If your pet is on a specific formula, set a recurring order once you confirm availability rather than assuming it will be restocked.
Online-first retailers may carry deeper inventory of a given food line, while store-linked retailers may stock a narrower set of sizes on shelves. That matters if you feed a large breed or a multi-pet household and go through food quickly.
Toys, Litter, Grooming and Accessories
This is where the in-store versus online trade-off is sharpest. Online, you rely on product photos, dimensions and reviews, which is workable but slower for first-time purchases. Compare which retailer is faster in practice before you order.
For a new puppy, check the sizing chart for crates, playpens and harnesses against your dog's current and expected adult weight, and confirm the return window in case the fit is wrong.
Grooming tools, dental chews, waste bags and pee pads are high-frequency consumables. These are the items where a subscription and a consistent in-stock supply matter more than browsing.
Availability, Out-of-Stock Handling and Substitutions
Availability is the hidden variable in any selection comparison. Before you commit to a retailer for a staple, check:
- In-stock status on the exact size and flavor. Product pages often show a range of sizes, and only some are in stock.
- Backorder and restock messaging. A clear restock date is more useful than a generic "out of stock" label.
- Substitution and auto-ship behavior. If an item is unavailable when a recurring order ships, some programs skip it, some substitute, and some delay the whole order. Know which before you rely on it.
Watch out: relying on a single retailer for a prescription diet without confirming stock can leave you scrambling if the formula is backordered, so keep a second source in mind for medical diets.
Which Shopper Each Model Suits
The selection question comes down to shopping style. If you reorder the same food, litter and consumables and want the full range online with scheduled delivery, an online-first retailer usually fits better. If you want to see and feel durables before buying, need an item today, or prefer to return in person, a store-linked retailer has the edge. Many households use both: a store for immediate and tactile purchases, and an online subscription for heavy, repetitive staples.

Chewy vs PetSmart Autoship: Recurring Order Discounts Compared
Many shoppers ask about recurring deliveries, and the terms matter more than the headline. Both retailers may offer recurring-delivery programs, and the terms, discount levels and cancellation rules can differ.
When you compare, look past the percentage. Check whether the discount applies to every item or only some, how far ahead you can change the schedule, and whether you can skip a delivery without penalty.
Confirm the program terms on each retailer's own site, since they change.
Petco Same Day Delivery: Where It Helps and Where It Doesn't
Same day delivery, where a retailer offers it, can help when you have run out of something urgent. Get practical tips for faster supply delivery. Eligibility depends on your location, the item and the time you order.
For planned restocking, standard shipping from an online retailer is often the simpler choice. A reorder that arrives in a few days on a schedule may cost less and remove the need to think about it at all.
Chewy Pharmacy vs Petco Pharmacy for Prescription Pet Medications
If your pet needs a prescription, the pharmacy process matters as much as price.
Confirm with your veterinarian's office which pharmacy they prefer to work with, since some practices have direct arrangements. Check each retailer's current requirements, including how to submit a prescription and what happens if a medication is out of stock.
We recommend comparing the current prescription steps on each retailer's site rather than relying on older reviews.
Pricing, Shipping Costs and Returns: A Like-for-Like Basket Approach
Sale prices on a single day tell you little about the total cost of buying from a retailer. That tells you almost nothing, because the item on sale this week is rarely the item you buy every month. The only fair way to compare is a like-for-like basket: the same brand, size and quantity, bought on the same day, with shipping, taxes, subscriptions and promotions included in the total.
How to Build a Like-for-Like Basket
Pick five to seven items you actually reorder. A typical dog or cat basket might include:
- One staple dry food in the exact bag size you buy (for example, a 30-pound bag of a national brand)
- One case of wet food in the same can count and flavor
- One bag of treats in the same weight
Then follow four rules so the comparison holds up:
- Same day, same session. Prices and promotions change weekly. Record the date and time you captured each price.
- Log in or use the same guest status at both retailers. Some prices and offers differ for signed-in customers, first-time buyers and loyalty members.
- Add the full total, not the item subtotal. Include shipping, taxes, any membership fee and any subscription discount you would actually qualify for.
- Note availability. A lower price on an item that is out of stock or backordered is not a real saving.
A simple spreadsheet with columns for item, brand, size, retailer, item price, shipping, discount and total is enough. Repeat the exercise once a quarter, because the answer changes.
Shipping Costs and Delivery Mechanics
Shipping is where the two models diverge most. Online-first retailers often use order-size thresholds for free shipping and may offer scheduled delivery through a subscription program, while store-linked retailers may combine standard shipping with pickup options where available.
When you compare shipping, check these specifics rather than the headline:
- Free-shipping threshold. What is the minimum order, and is it based on subtotal before or after discounts?
- Oversized-item surcharges. Food bags over a certain weight, litter, crates and large beds often carry extra fees that are not obvious until checkout.
- Delivery window. Standard, expedited and same-day options differ by ZIP code. Enter your actual ZIP code at checkout rather than trusting a generic estimate.
Watch out: a free-shipping threshold that is a few dollars above your usual basket can push you to add an item you do not need, which erases the saving.
Returns, Refunds and Problem Resolution
Return policies look similar in summary and differ in practice. Compare these points side by side:
- Return window. How many days from delivery, and does it differ for food, medication, opened items and large supplies?
- Who pays return shipping. Some retailers provide a prepaid label; others deduct return shipping from the refund.
- In-store returns. A store-linked retailer may accept online returns in person, which is faster than shipping an item back.
Keep your order confirmation, take a photo of any damage before discarding packaging, and start the claim through the retailer's help center so there is a written record. Follow a step-by-step guide to returning damaged items. If a resolution stalls, escalate to the customer-service phone line and reference the case number.
The Total-Cost View
A basket comparison is only the starting point. Model your recurring purchases over a month and a year: multiply your monthly food, litter and treat spend by twelve, then subtract any subscription savings and add any delivery fees you would actually pay. That annual figure, not the one-time basket total, is what you are really choosing between.

Frequently Asked Questions

Frequently Asked Questions
Should I buy from Chewy or Petco?
The better choice depends on what you buy most often. Chewy is strong for online ordering, a wide range of food and supplies, and autoship. Petco is useful if you want to combine online orders with in-store pickup, grooming or veterinary services near you. Compare the specific items you buy, the shipping cost to your address, and whether recurring discounts apply to your order size before deciding. Current prices and delivery options can change, so check each site directly before you order.
Is Chewy cheaper than Petco for pet supplies?
Prices vary by product, brand, order size and promotions, so no retailer is cheaper across the board. To compare fairly, build a basket of the same items on both sites, include shipping and any autoship discount, and check the total at checkout. A like-for-like basket is more useful than comparing a single product or a sale price. Shop and Bark does not publish a price comparison here, so verify current prices on each retailer's website.
Does Petco offer same day delivery?
Some retailers offer same day delivery in certain areas. Availability depends on your ZIP code, the items in your cart and the time you order. If you need supplies quickly, enter your address at checkout to see which delivery options are offered. Check the cutoff time and whether all items in your order qualify, because a mixed order may ship on a slower schedule.
Can I return online purchases from Petco to a physical store?
Petco's return options can vary by item and order type, so review the current returns policy on its website before buying. Many shoppers want to know whether they can bring an online order back to a store, which is a common convenience for pet retailers with physical locations. Keep your order confirmation and packaging, and contact customer service if an item arrives damaged or incorrect. Shop and Bark's own return and support policies should also be checked on its website.
