Is The Auto-Replenishment Opportunity Just For The Dogs?
Autoship or auto-replenishment has paid off handsomely for Chewy, but apparently hasn’t been gaining major traction with retailers outside the pet foods category.
In the third quarter, Chewy sales to Autoship customers represented 83% of sales, with sales expanding significantly faster than to non-subscribers. The free program offers 35% off your first order and a 5% discount on future orders.
Chewy CEO Sumit Singh said on the retailer’s third-quarter analyst call, “Autoship is a rinse and repeat product merchandise program that has high reliability and accuracy, both in terms of planning, in terms of delivery and high satisfaction rating.”
Singh added that the order predictability “allow[s] operational planning to reduce cost and grow margin in a way that gives Chewy unique structural competitive advantages.”
Among competitors, PetSmart, the largest U.S. pet retailer, just launched a campaign to win $1,000 of orders via its own Autoship program, perhaps to counter the success of Chewy. Petco has a similar program, Repeat Delivery, but its e-commerce approach is undergoing a reset.
Several subscription programs have found success with replenishment subscriptions that allow consumers to automate purchases in certain commodity items, such as coffee (i.e., Trade Coffee), razors (Dollar Shave Club), diapers (Coterie), cleaning products (Blueland), and vitamins (Persona Nutrition).
Auto-Replenishment May Be Attractive in Some Cases, But Has Drawbacks
McKinsey finds replenishment-based subscription models have higher conversion rates and less churn than other subscription models, but subscribers are highly motivated by financial incentives, such as discounts, that can weigh on margins.
Many mass sellers that potentially could benefit from delivering household staples on a monthly auto-pilot have lately been focusing investments on same-day delivery.
Amazon’s Subscribe & Save program, launched in 2010, offers Prime subscribers the ability to save up to 15% off when receiving five or more products in one auto-delivery to one address. In 2023, Amazon noted that it had passed on more than $1 billion in savings over the prior 12 months to subscribers globally. Amazon said at the time, “That’s tens of millions of customers never running out of the things they reorder most, like coffee, diapers, dog food, toilet paper, cleaning supplies—even socks.”
Walmart only launched a subscription program in 2023 as a convenience, with no discount applied. Walmart said at the time, “When customers shop Walmart.com or the app, their baskets often contain repeat items, which means precious time is spent every weekly shopping trip finding and adding the items they’ve purchased countless times before.”
Target in 2020 discontinued its Subscriptions replenishment service, telling Bloomberg that the majority of Subscriptions guests “shifted away from regular deliveries to enjoy the speed and flexibility of our same-day services.” Walgreen’s also recently discontinued its Auto-Reorder & Save program.

In past studies we have done on this, auto-replenishment only really works for products that are bought habitually, used at a predictable rate, and which are essential. Something like pet food broadly falls into those buckets. So too do things like toilet paper, laundry detergent, diapers and so forth. However, to work really well, services have to offer flexibility – including the ability to pause deliveries and provide some level of price reassurance. Feeling a lack of control is a major reason for consumers not signing up to these services, or for cancelling them.
This doesn’t seem like a terribly hard question to answer: people buy the same pet-food, week-in,week-out….automating the process makes sense. I’d be hard pressed to think of a similar buying pattern with a drug store
Auto-replenishment works exceptionally well in the pet category because the underlying behavior is highly predictable, emotionally driven, and necessity-based. Pet owners don’t just buy products — they maintain a routine for feeding and care, which makes recurring delivery feel natural rather than forced. Chewy’s Autoship program is the clearest proof point: subscription orders account for roughly 80% of total sales, demonstrating how deeply replenishment aligns with the category’s consumption patterns. The convenience factor is enormous, but so is trust. Pet parents want reliability and consistency, and subscription programs deliver predictable deliveries, personalized promotions, and loyalty benefits that reinforce long-term engagement. In short, auto-replenishment succeeds where the purchase cycle is obvious and the emotional stakes are high.
That same dynamic explains why mass chains and drug stores have struggled to replicate similar success with staples. Grocery and drug assortments are far more variable—households change brands, quantities, and purchase timing in response to promotions, health trends, or seasonal behavior—which makes rigid automation less appealing. Many everyday categories simply lack the habitual certainty that dog food or litter provides. Consumers also want control when prices fluctuate or when they’re experimenting with new products, so auto-replenishment can feel restrictive rather than helpful. The pet category benefits from a unique intersection of repeat need, emotional loyalty, and digital-first purchasing — conditions that don’t always exist in other staple retail segments.
The bigger lesson for retailers isn’t to blindly copy subscription models, but to design replenishment around true customer behavior. Programs work best when they remove friction — ensuring customers never run out of essentials — while still offering flexibility and transparency. Retailers can apply these principles by improving product data, using AI-driven personalization to anticipate needs, and positioning subscriptions as a convenience tool rather than a lock-in strategy. Auto-replenishment succeeds when it aligns with real-world routines; when it doesn’t, it becomes just another feature that customers ignore.
One thing I didn’t see mentioned was customer experience. Auto-replenishment can absolutely make life easier, and Chewy’s CX, in my opinion, is really strong. The need for pet supplies is also highly predictable. But I think the issue may be that other companies overstate the demand for auto-replenishment when their investment in the functionality, and the overall experience, doesn’t fully deliver. In that case, a discount won’t move the needle.
Chewy’s does a good job with their CX. It’s really easy as a customer to make adjustments on timing and items.
The problem is when there is any variability in the rate of consumption. I had a Chewy subscription and it was great…right up to the moment my dog became a finicky eater and wanted a little variety in his diet. I start rotating other food into his diet, and before you know it, the Chewy deliveries are piling up. Subscription cancelled. Variable consumption made auto-replenishment not viable.
Pharmacy prescription refills are a great candidate. There’s something where there shouldn’t be too much variability in consumption. Mine aren’t truly on auto-fill, but I do get a text from my pharmacy saying it’s time, should they process it? Yes. I’m noticing that I’m down to a couple days worth, but responding to a text is slightly easier than initiating my own call or text.
Full blown auto-fill might be too much to ask for a lot of products, but if the retailer can build in some kind of pause or promt mechanism, it might expand the universe of products where programmed refills/replenishment are viable.
Pets are apparently more predictable (and loyal) than people. I like the idea of subscribing. I keep trying it. But I rarely get it right. I haven’t given up and have a couple on the board. If it works, it will make this shopper very happy. So convenient! One less thing to think about.
Maybe we should let the pets decide on their auto replenishment and loyalty experience ? 😉
Of course, auto replenishment for pets is great as long as what you need is in stock. I need an eye drop (OTC for dry eye) for a pet and when I could get it regularly shipped, great! Then the out of stock hits and it’s been months and now I am running out. Having a good process for out-of-stocks is key, especially for must-have items!
In addition to the pet food industry, autoreplenishmemt works well in vitamin supplements and prescription medicine because of the predictable consumption. However, in all cases, the retailer must alert the customer of an upcoming shipment, allow the customer to cancel or reschedule the shipment, and change the replenishment cycle. I should add that, in the case of prescriptions or supplements, the replenishment cycle should always be an exact multiple or fraction of the unit content of the package.
Pet stores do well on auto replenishment because pet food consumption and grooming supplies are predictably used and calendar driven items, especially as shoppers hold confidence in Chewy’s pricing and/or quality. For replenishment to work at mass chains or drug stores, most have a mixed bag of quality and without low price leadership, which makes it harder for shoppers to pull the trigger on planned purchases.
