How to Plan Shopify Pet Product Bundles for Treats, Food, and Toys

A treat brand owner gets the same three messages every week. One shopper asks which flavor to try first. Another asks if a bigger bag comes cheaper. A third wants a gift box for her sister's dog, but doesn't know what the dog eats.

Each of those questions needs a different bundle, and pet catalogs make bundling harder than most. Treats come in several proteins and flavors, toys come in sizes and chew strengths, food is heavy to ship, and many products have best-by dates. A single "starter kit" product or a store-wide discount code can't answer all of that, and free shipping on a heavy bundle can quietly wipe out its profit.

Getting this right matters because pet parents buy food and treats over and over. The right bundle can turn a first order into a routine purchase. The wrong one leaves you with stock in flavors nobody picked.

The best pet product bundles follow the way pet parents actually shop: to try, stock up, choose, start, care, give, and repeat. This guide shows which bundle format fits treats, food, toys, grooming, supplements, starter kits, gifts, and subscriptions. It also covers the rules that keep bundles safe and easy to pack, how to price them, and what Shopify can and can't do without an app.

Short answer: The best Shopify pet product bundles match how pet parents shop: variety packs for trying flavors, volume tiers for stocking up, build-your-own boxes for picky pets, starter kits for new puppies and kittens, care kits for grooming and supplements, gift boxes, and subscriptions for refills. Shopify's free Bundles app handles fixed kits and multipacks. Boxes that customers fill themselves need a bundle app, and subscription bundles need an app that supports subscriptions.

TL;DR

• Build pet bundles around seven buying jobs: try, stock up, choose, start, care, give, and repeat.

• Use variety packs and build-your-own treat boxes for flavors and proteins, and use volume tiers for food a pet already eats.

• For toys and accessories, ask for the pet's size first, and keep dog and cat products in separate bundles.

• Price the whole bundle, including packaging and shipping, because heavy food and free shipping can erase a bundle discount.

• Shopify's free Bundles app covers fixed kits and multipacks. Mix-and-match and build-your-own boxes need a bundle app, and Shopify bundles can't be sold with Shopify's subscription purchase options.

• Start with two or three bundles: one variety pack, one stock-up tier, and one starter kit or gift box.

What are pet product bundles?

Pet product bundles are two or more pet products, or several variants of one product, sold together as one offer. The store can choose the contents as a fixed kit, or the shopper can build the pack. A bundle usually comes with a bundle price, a discount, or a free gift.

Pet stores are a natural fit for bundles because so much of the catalog is bought again and again. The American Pet Products Association (APPA) reported that U.S. pet industry spending reached $158 billion in 2025, and food and treats were the largest category at $68.3 billion. Those are repeat purchases, and repeat purchases are where bundles work best. Pet catalogs also have plenty of variants, such as proteins, flavors, and sizes, and plenty of gift buyers who need help choosing.

Most pet product bundles fall into one of five formats:

Knowing the difference between fixed and mix-and-match bundles saves time later, because it decides which Shopify tools you can use. The same goes for how mix-and-match bundles work on Shopify, since variety packs and treat boxes are both mix-and-match formats.

Match each pet bundle to how pet parents buy

Start with the job the pet parent is trying to get done, then pick the format. Pet parents buy in seven repeatable jobs, and each one points to a different bundle:

Most stores only need three or four of these jobs. Pick the ones your customers already ask about in emails, reviews, and at the counter. A bundle that doesn't serve a clear job usually turns into slow stock with a discount on it.

The Give job is seasonal for most stores, and personalized holiday gift boxes for pets work best when they're planned around who is buying, such as pet parents, friends without pets, or donors to a shelter.

Dog treat bundles and build-your-own treat boxes

Treats are the easiest first bundle for most pet stores. They're light, they sell often, and dogs have strong opinions about flavor. Dog treat bundles usually take one of two shapes.

A treat variety pack uses one treat line in mixed flavors or proteins, such as "any 6 chews." A build-your-own treat box lets shoppers pick from several treat products, such as jerky, biscuits, and dental chews, in one box.

A few rules keep a treat box easy to choose:

• Show the protein and main allergens on every choice. Many owners shop around chicken or grain sensitivities, and they won't guess.

• Set a clear minimum and maximum, and put the number in the step title, such as "Pick 4 treats."

• Limit how many of one flavor fit in a pack if the point is variety. In a PushBundle Mix & Match pack, the Number of variants limit sets how many different flavors a pack needs, and Quantity per variant caps how many of each.

• Offer a single-protein option for dogs with allergies, so those owners don't leave.

• Keep shelf lives close. Put treats with similar best-by windows in the same box, and sell older stock first, so one item doesn't expire long before the rest.

The same advice works for cat treats. Shoppers search for "cat treat bundle" and "cat treat pack" too, so a smaller cat box is worth building if you carry a cat line.

The step logic is similar to a snack box customers can build themselves: one decision per step, with limits that match the physical box.

Pet food variety packs and stock-up bundles

Pet food bundles do two different jobs, and each needs its own format. A variety pack helps a pet try new flavors. A stock-up bundle rewards buying more of the food the pet already eats.

Variety and sample packs suit wet food cans, pouches, toppers, and sample-size bags. Shoppers search for "dog food variety pack," "cat food variety pack," and "pet food sample packs," which shows how often owners want to test before they commit. A mix-and-match pack with a fixed size, such as 12 cans in any flavors, keeps it simple.

Stock-up tiers work better for dry food. A pet parent who already buys one 12 lb bag doesn't need to build anything. They need a clear reason to buy two or three, such as "2 bags save 10%, 3 bags save 15%." Volume tiers are the right tool for this. Mix-and-match packs for food brands follow the same split, as food and beverage bundles on Shopify show for drinks and snacks.

Three things to watch with food bundles:

• Shipping weight. Shopify bundles don't have their own shipping profiles. Shopify takes the shipping rate from each product's profile and calculates weight from the individual items. Before you offer free shipping on a 3-bag tier, check what that box actually costs to ship.

• Keep packs separate by type. Don't mix dog and cat food, or wet and dry food, in the same choice list.

• Switching foods. If a variety pack introduces a new food, tell shoppers to follow the food maker's transition directions on the label.

Unclear savings are one of the most common problems with volume bundles, so show the price per bag at each tier.

Dog toy bundles and build-a-box toy sets

A dog toy bundle should start with the dog, not the toy. Size and chew strength come first, because a toy that's fine for a small, gentle chewer can be the wrong choice for a large dog that destroys toys in minutes.

Shoppers search for "dog toy bundle for large dogs," which says a lot about how they shop. The simplest way to handle this is a separate box for each size, or a first step where the shopper picks a size and then sees only toys labelled for that size.

Theme boxes help owners choose quickly. A few that work well are "tug and fetch," "puzzle and enrichment," and "plush for gentle chewers." Label chew strength clearly on every toy, and don't mix puppy and adult toys in the same choice list without labels.

Toys don't expire, so a toy box is a good place to sell one bestseller alongside a few slower toys. Keep the choice list short, though. Too many options in one step is one of the common reasons mix-and-match bundles don't convert, and it slows down gift shoppers even more. If you have toys that have sat on the shelf for months, using bundles to move slow stock works better than a deep discount on the toy alone.

Holiday toy boxes are popular too, and shoppers search for "dog toy bundle christmas." A December toy box can use the same steps with a holiday box and a gift card added.

Puppy and kitten starter kits

A starter kit answers one question: "What do I need?" New owners are often overwhelmed, so a kit that covers the first week is one of the most useful bundles a pet store can sell.

A puppy starter kit usually includes:

• A small bag or sample of food

• Food and water bowls

• A collar and leash, or a harness

• Small training treats

• A chew toy suited to puppies

• Poop bags

• A brush or grooming mitt

A kitten starter kit usually includes food, litter, a scratcher, a toy, and a brush.

If every item comes in one size, a fixed kit made with Shopify's free Bundles app works well. Collars and harnesses come in sizes, though, so many stores either let the shopper choose a size inside the kit or use a build-your-own box with a size step.

Kits sell well in three levels, such as Basic, Complete, and Premium, because new owners can compare them quickly. The same good, better, best price tiers that work for holiday bundles work here all year.

Starter kits also suit breeders who send puppies home with supplies, and shelters that give adopters a first-week pack. Those buyers often want their own pricing, which is covered in the section on vet clinics, breeders, and shelters below.

Pet grooming kits

Grooming kits work best when they're built around the pet's coat and the job, not around your product categories. A pet parent shopping for a double-coated dog wants the right brush and shampoo together, not a random mix of grooming items.

Common grooming kits include:

• Bath-day kit: shampoo, conditioner, a brush, and a towel

• Coat-type kits: short coat, long coat, or double coat

• Nail and paw kit: clippers or a grinder, paw balm, and wipes

• Travel kit: waterless shampoo, wipes, and a compact brush

A fixed kit suits shoppers who want everything at once. A cross-sell bundle suits shoppers who came for one product, such as offering the matching brush on the shampoo page. Cross-sells only work when the pairing is obvious, which is why cross-sell bundles that shoppers ignore usually pair products that don't belong together.

Liquids can leak in transit, so pack a grooming kit and ship a test box to yourself before you list it.

Pet supplement bundles and the claims to avoid

Supplement bundles suit pets that take something every day, such as joint support for a senior dog or a daily probiotic. A volume tier works for one supplement a pet already takes, and a small fixed bundle works for pairings like joint chews with fish oil.

Supplements need more care with wording than any other pet bundle. In the U.S., animal supplements don't have their own regulatory category the way human supplements do. The National Animal Supplement Council (NASC) explains that the human supplement law doesn't cover animal products, and that the FDA regulates them as food or drugs depending on how they're marketed. A claim that a product treats or prevents a disease can make it look like an unapproved drug.

That affects how you describe the bundle, not just the product:

Keep the wording the product maker uses on its label, and don't add stronger claims in the bundle title or description. Many stores also prefer products from NASC Quality Seal members. This isn't legal advice, so check with the maker or a compliance professional if you're unsure.

Don't combine supplements and treats in a way that suggests the box is a complete diet or a medical plan.

Pet gift boxes for holidays and non-pet owners

A pet gift box has to work for someone who often doesn't know the pet well. The buyer might know it's a dog, but not its size, its diet, or its favorite flavor. So keep the choices few and simple.

A good gift box asks only for species and size, offers at least one treat option that suits most pets, and adds a greeting card and a gift message. In PushBundle's Build Your Own Box, those are separate steps: Add Box for the packaging, Gift Card for a greeting card (not a Shopify gift card), and Form Builder for the message.

Holiday gifting is the busiest season for pet gift boxes, and holiday pet gift boxes with personal touches, such as name tags and custom cards, help them stand out.

Pet gift boxes aren't only for holidays. Shoppers also search for pet sympathy and pet loss gift boxes, which people send to friends who have lost a pet. If you offer one, choose gentle products and write the copy with care.

Pet subscription boxes and refill bundles on Shopify

Pet food and treats run out on a schedule, so subscriptions fit pet stores well. Most pet subscriptions are one of two kinds. A refill subscription sends the same food or treats on a schedule. A curated or build-your-own box subscription sends a monthly mix of treats and toys. Shoppers search for "pet subscription box," "dog treat box subscription," and "dog treat boxes monthly."

There's one important limit to know before you plan a subscription bundle. Shopify's Help Center says bundles aren't compatible with purchase options such as subscriptions, and aren't compatible with the Shopify Subscriptions app. So a pet subscription bundle needs either a subscription app with its own box or bundle builder, or a bundle app and subscription app that are built to work together. A bundle app such as PushBundle handles the bundle itself, and the recurring billing comes from a subscription app. Check that the two support each other before you launch.

A few things make pet subscriptions easier to keep:

• Let subscribers skip, swap flavors, and change the schedule. Pets change their minds, and so do their appetites.

• Base the default schedule on how long the pack lasts. For example, if the feeding guide on the label means a bag lasts about four weeks for an average dog, a four-week schedule is a sensible default. Let owners change it.

• Plan for stock-outs. Decide what happens when a flavor sells out mid-cycle, such as a swap to a similar flavor with an email.

Pricing needs extra care too. Subscription bundles on Shopify usually carry a discount on every order, and pricing a subscription box has to cover packing and shipping on each delivery, not just the first one.

Bundles for vet clinics, groomers, breeders, and shelters

Some of your best bundle buyers may not be pet parents at all. Vet clinics, groomers, breeders, and shelters buy in larger amounts and often need their own bundles and prices.

A few examples:

• A breeder's puppy pack sold in sets of six, one for each puppy going home

• A shelter donation bundle of food and treats at a special price

• A groomer's restock pack of shampoo and wipes

On Shopify, you can tag these customers, for example with "Breeder" or "Vet clinic," and show a bundle only to them. In PushBundle, the Customer eligibility setting lets you pick Customer tag, and only logged-in customers with that tag see the bundle. That keeps trade pricing separate from your public prices.

If you also have a shop counter or a clinic front desk, selling the same bundles at the counter with Shopify POS means staff can sell the same kits in person.

How to price pet product bundles without losing margin

Price pet product bundles on the whole order, not just the discount. Add product cost, packaging, packing time, and shipping, then decide how much you can give back as a discount or reward.

Here's an illustrative example for a "Pick 4" dog treat box:

In this example, free shipping takes more than 40% of what's left. A free sample treat that costs you $1 might be a better reward for this box. Free shipping makes more sense on light bundles, or on tiers big enough to carry the cost.

Common pet bundle offers include:

• A percentage off the bundle

• A set price for the pack, such as "any 6 chews for $30"

• A free gift, such as a sample treat or a roll of poop bags

• Free shipping, on light bundles only

If you use quantity tiers in a PushBundle build-your-own box, only the highest tier a shopper reaches applies. Make sure each higher tier is worth more than the one below it.

One more rule: don't discount your best-selling food bag on its own. Put the discount on the bundle that adds the second item, so the discount actually grows the order. The real profit after packaging, shipping, and fees is the number to check, and bundle pricing that avoids over-discounting matters even more during sales periods.

Worked example: a build-your-own dog treat box in PushBundle

A treat box is the most common build-your-own bundle format for pet stores, because the choices are simple and the items are light. Here's how a "Pick 4" dog treat box looks in PushBundle, a Shopify bundle app by WhenLab. Build Your Own Box is on the Growth plan, which costs $14/month (or $134.40/year) and has a 14-day free trial.

1. Turn on the app embed. In your theme, enable the PushBundle app embed so bundles can show on your store.

2. Create the box. Go to Apps > PushBundle > Create Bundles and click Create BYOB Bundle. Name it the way a shopper would search for it, such as "Build Your Dog's Treat Box."

3. Add the treat step. Add a Choose Product step with the Step Title "Pick 4 treats." Click Browse to choose your treats, or add a whole treat collection. Set the Min product limit and Max product limit to 4, and turn on Make this product step required. The docs explain how to set min and max items in a product step.

4. Add an optional toy step. Click + Add step, choose Choose Product, and call it "Add a chew toy." Set the maximum to 1 and leave it optional.

5. Add packaging and a card if it's a gift. Add an Add Box step for a gift box, and a Gift Card step for a greeting card.

6. Set the price. Choose the sum of picked items with One discount, or one set price for the whole box. Set-price boxes aren't priced on Shopify POS yet, so use a discount instead if you sell the box in store.

7. Pick a layout. Under Template & appearance, choose a layout and preview it on mobile.

8. Publish and test. Click Publish, then Publish now, then Publish to storefront. Place a test order and check that each treat shows on the order with Part of: and the box name.

PushBundle's docs on creating a Build Your Own Box bundle list the remaining settings, such as quantity tiers and layout options.

If you're bundling one treat line in several flavors, a simpler setup works. A Mix & Match Single Product pack, such as "Pack of 6, any flavors," uses the Number of variants and Quantity per variant limits to keep the pack varied. On the free Starter plan, a Volume bundle can do something similar. Its How shoppers choose variants setting lets shoppers mix variants in one tier.

Shopify Bundles app vs a bundle app vs a subscription app

Shopify's free Bundles app is enough for a few fixed kits and multipacks. Customer-chosen boxes, tiers, and free gifts need a bundle app, and recurring orders need a subscription app.

Shopify's free Bundles app handles fixed bundles and multipacks, and Shopify's Help Center says it doesn't support mix-and-match bundles. Fixed bundles can hold up to 30 components, with a maximum of 3 options and 100 variants per bundle. If a component's price changes, the bundle price doesn't update on its own.

When you compare apps for a pet store, look for:

• Limits per flavor or variant, so variety packs stay varied

• Steps or size choices, so toy and gift boxes stay safe and simple

• Inventory deducted per component, so you know what's in stock

• Order lines your packer can read without opening the app

• Shopify POS support, if you have a shop or a clinic counter

• Subscription support, if refills are part of your plan

Most of the gaps in that table come from native Shopify bundle limitations that remain even after Shopify's Spring '26 bundle changes. Apps differ most on customer-chosen boxes. Build-your-own bundle apps vary in how they handle steps and limits, while general Shopify bundle apps vary more in tiers, cross-sells, and plan costs.

Which pet bundles to launch first

Start with three bundles, not ten. A small pet store learns more from three bundles that are easy to manage than from a full catalog of kits that are hard to keep in stock.

1. One Try bundle. A treat or food variety pack brings in new customers who aren't sure what their pet will like.

2. One Stock up tier. Put volume tiers on your best-selling food or treat, so regular customers buy more each order.

3. One Start or Give bundle. Run a starter kit all year, and add a gift box from November.

Add a subscription once you know which flavors people reorder and how often. Track bundle revenue and reorders, and retire any bundle that doesn't sell after a set period, such as 60 days. Fewer bundles also make planning bundle component stock easier, because each bundle draws on products you already track closely.

Common pet bundle mistakes

Most pet bundle problems come from treating pets like any other product category. These are the mistakes to avoid:

• Mixing dog and cat products in one choice list. Build separate bundles for each species.

• Selling toys without size or chew-strength labels. Put the size choice first.

• Combining treats with very different best-by dates. Keep shelf lives close, and sell older stock first.

• Offering free shipping on heavy food tiers. Check the real shipping cost first.

• Putting too many flavors in one step. Keep each step to a short list.

• Adding health claims to supplement bundles. Use the maker's approved wording.

• Launching a subscription before you know reorder timing. Watch reorders for a few months first.

• Skipping the test order. Check that every item shows on the order and the discount applies.

Limitations to know before you build pet bundles

Every tool has limits, and knowing them early saves rework:

• Shopify's free Bundles app doesn't support mix-and-match bundles.

• Shopify's documentation states that bundles aren't compatible with subscriptions, pre-orders, or the Shopify Subscriptions app, and can't be used in exchanges.

• Shopify bundles don't have their own shipping profiles, so heavy components set the shipping cost.

• On Shopify, the bundle can only sell as many units as its lowest-stock component allows.

• Shopify's Google & YouTube channel supports fixed bundles only, so a build-your-own treat box can't run as a Shopping ad product.

• In PushBundle, Build Your Own Box, Mix & Match, and cross-sell bundles are on the Growth plan. Set-price build-your-own boxes aren't priced on Shopify POS yet.

• A bundle doesn't change the labeling rules for each product inside it, and supplement claims are still subject to FDA and state rules.

Conclusion

Pet product bundles work when they follow the pet's routine. Pet parents want to try flavors, stock up on what works, choose for picky eaters, get set up for a new puppy, take care of grooming and health, give gifts, and never run out. Match each of those seven jobs to the right format, keep the choices short, and price the bundle with shipping and packaging included.

Start with three bundles, place a test order, and add more once you see what sells. PushBundle is one way to build the formats Shopify's own Bundles app doesn't cover, such as variety packs, build-your-own treat boxes, and volume tiers. As gifting picks up, personalized holiday gift boxes for pets are a natural next step.
