Pet store online shop: what it needs to actually sell
A pet store sells lots of similar products to customers who come back often. Here is what an online shop for the industry needs (catalog, filters, product pages, WhatsApp ordering and bookings) and how I built it for Mecohue.

A pet store online shop has to solve one specific thing: letting customers quickly find the food or accessory they always buy, add it to the cart and place the order without calling. For that you need a catalog with good search and filters, clear product pages and a simple checkout, which for many pet stores works better over WhatsApp than with online payment.
I'll walk you through the pieces it needs, the decisions worth making before you start and how I solved it for Mecohue, a pet store with a veterinary clinic in Wilde, Buenos Aires.
Why doesn't a pet store sell online like any other shop?
A pet store has a peculiar catalog: many brands of food, each in several sizes and for different life stages or breed sizes, plus accessories, cat litter, toys and grooming products. The products are similar to each other, and customers usually know exactly what they want: the same bag they bought last month.
That changes the priorities. In a clothing store, photos and discovery matter; in a pet store, what matters is that search works, that filters take you to the right brand and that repeating a purchase is quick. And there is another detail: many pet stores also offer grooming or have a vet practice, so the same website can be used to book appointments.
What does a pet store online shop need?
These are the pieces you can't skip. On Mecohue's public site, there's no payment and no prices shown: everything ends in a WhatsApp conversation.
- Catalog with search, filters and sorting. Customers type the brand or filter by category, find the product in seconds and can sort the results.
- Product page with a gallery. Several photos, a description and the information customers need so they don't have to ask you.
- Simple cart. Add products, change quantities and see the summary before sending the order.
- Closing on WhatsApp. The order or the question lands in the store's WhatsApp with the product already written. At Mecohue, each product has a “check availability on WhatsApp” button that opens the chat with the product filled in.
- Booking for services. If you offer grooming or vet services, each service should explain what it includes and how to book (at Mecohue, it’s over WhatsApp).
- About page with a map. Who you are, where you are and how to get there, with Google Maps embedded.
- Works well on a phone. Most of your customers will visit from their phone, so the design has to be built for small screens first.
WhatsApp orders or online payment?
This is the first decision, and there is no single answer. Online payment (with MercadoPago or another payment gateway) makes sense when you sell to customers you don't know, ship to other areas or have enough volume to justify the fees. WhatsApp ordering makes sense when your customers are from the neighborhood, already know you and want convenience: see what's available, put together the order without mistakes and have you confirm it.
At Mecohue we went with the simplest option: the website has no cart and shows no prices. Each product has a “check availability on WhatsApp” button that opens the chat with the product already written, and the store replies with price and availability. Home delivery covers Wilde and nearby. That way we used the channel where they were already serving customers, without changing how they get paid. If the business needs it later, online payment can be added on top of the same shop. I explain what defines the cost of each path in how much an online store costs in Argentina.
What should a pet store website look like?
Many websites in this industry look alike because they come from the same template: the same banner, the same stock photos. Nothing wrong with that, but it says nothing about the business.
For Mecohue we went for a warm, colorful design: orange, turquoise and yellow on a cream background, bold rounded headings and illustrations of dogs and cats. The idea is for the site to feel like the neighborhood store you visit with your pet: friendly, cheerful and easy to browse on a phone.
This isn't a rule: the design has to reflect what your business is like. But it's worth asking what image you want to project before picking a template. I go deeper into this in custom website vs template.
What is Mecohue's online shop like?
Mecohue is a pet store with a veterinary clinic that has been operating in Wilde, Buenos Aires. Before the platform they had no online channel where customers could see products or book an appointment: only social media.
I built them a public site with a catalog (search and filters by species and category), each product with its sizes and a button to check availability over WhatsApp, clinic and grooming services booked over WhatsApp, home delivery in Wilde and nearby, and a WhatsApp button always within reach. Images are optimized so the site loads fast on phones.
The difference from a standalone shop is that the public site is one of three parts of the same system: the other two are the clinic management and the store's point of sale with inventory. How those parts connect is in the story of how Mecohue left spreadsheets behind.

Three ways for a pet store to sell online, depending on where the business is:
| Catalog with WhatsApp ordering | Platform (Tiendanube, Shopify) | Custom shop connected to the store | |
|---|---|---|---|
| How the sale closes | The order arrives on WhatsApp and you confirm it. | Cart and online payment inside the platform. | However you decide: WhatsApp, online payment or both. |
| Design | Your own, if custom-built. | Within the platform's templates. | Your own. |
| Monthly cost | Server and domain. | Platform subscription and fees depending on the plan. | Server and domain; no platform fees. |
| Connection to the store's register and inventory | Only if built that way. | Depends on integrations. | Yes, if built as a single system. |
| When it makes sense | Neighborhood customers who already message you. | To start fast or sell nationwide. | When the website has to talk to the rest of the business. |
The full comparison between selling on Mercado Libre, Tiendanube or your own shop is in the post linked below.
Should I use Mercado Libre or Tiendanube instead of my own shop?
For many pet stores, Mercado Libre (the big online marketplace in Argentina) or a platform like Tiendanube are a good way to start. The question is what you want the website to do: if it's only selling individual products nationwide, a platform may be enough. If you want the website to be the shop window of your store, with grooming or vet appointments and your regular customers, your own shop gives you more control. I compared them point by point in your own online store vs Mercado Libre or Tiendanube.
And if your pet store is also a vet clinic, the website is only one part. On my services page you can see what I build, and in management system for vet clinics and pet stores I go over the modules worth having behind the counter.
How much does an online shop for a pet store cost?
It depends on three things: how many products you have, whether you charge online or through WhatsApp and what has to talk to what. A catalog with WhatsApp ordering is the simplest version; if the shop also has to connect with the register, the inventory and the clinic, it stops being a standalone shop and becomes a custom management system. Tell me what you sell over WhatsApp or email and I will send you a fixed quote within 48 hours. You don't have to do everything at once: you can start with the catalog and add the rest later.
What should you have ready before you start?
- The product list. Name, brand, size, category and price. If you already have it in a spreadsheet, that's the best starting point.
- Photos. Of the products and of the store. Product photos can come from the supplier; photos of the store build trust.
- How you want to close orders. WhatsApp, online payment or both, and who answers.
- Delivery areas and method. If you deliver, where and how; if it's in-store pickup, during which hours.
- Services that need booking. If you offer grooming or vet care, which services can be booked and at what times.
Frequently asked questions
What does an online shop for a pet store need?
A catalog with search and filters (by category, brand, type of pet), a page for each product with photos, a simple cart and a clear way to close the order. If you also offer grooming or vet services, it makes sense to add appointment booking to the same site.
Can I take orders through WhatsApp instead of charging online?
Yes. At Mecohue, the website has no cart: each product has a button that opens WhatsApp (the main business messaging channel in Argentina) with the product already written, and the store replies with price and availability. It is a good way to start if you already serve customers on WhatsApp and don't want to add a payment gateway yet.
How much does an online shop for a pet store cost?
It depends on how many products you have, whether you charge online or through WhatsApp, and whether it has to connect with the register, the inventory and the clinic. Tell me about your store over WhatsApp or email and I will send you a fixed quote within 48 hours.
Should I use Tiendanube or build my own shop?
It depends on where the business is. A platform like Tiendanube (a Shopify-style e-commerce platform popular in Latin America) lets you start fast; a custom shop makes sense when you want your own design or need the website to connect with the rest of the business. I compare them in detail in the post on your own shop vs Mercado Libre and Tiendanube.
