PetLabCo lands 1,500-store PetSmart rollout after BC Partners takes majority stake

PetLabCo announced that four of its supplement SKUs are now on shelves at all 1,500+ PetSmart stores across the US.

The consensus read is that this is another DTC brand proving itself online and earning its way into mass specialty retail on the strength of customer traction. That reading is incomplete. The company's announcement references a majority stake investment from BC Partners in early 2025, and the timing matters because it changes what the distribution win signals about the brand's retail trajectory and what independents should read into it.

The deal structure and what it bought

PetLabCo is a supplement brand that built its base online and claims 5 million US customers and over 100,000 five-star ratings globally. The company said BC Partners took a majority stake in early 2025. The PetSmart announcement came after that investment was disclosed.

The four products now stocked nationwide are Tailored Probiotic Chews, ProBright dental powder, Joint Care Chew Advanced, and Tailored Allergy & Immune Probiotic Chews. The company describes each as vet-reviewed and formulated to support gut health, dental hygiene, mobility, and seasonal allergies. Chris Masanto, PetLabCo's co-founder and CEO, said the retail expansion reflects customer demand and is part of the brand's effort to serve more pet parents across the country.

Why the sequence reverses the usual DTC playbook

The standard story is that a DTC brand builds proof of concept online, generates enough velocity and margin to fund its own growth, and then uses that traction to negotiate shelf space with a mass retailer. The retailer places a brand that has already demonstrated pull.

PetLabCo's path ran the other direction. The company disclosed the private equity investment, then announced the nationwide PetSmart rollout. The shelf placement follows a capital event rather than demonstrated retail velocity. A brand with a large online customer base is now testing whether that base converts into in-store sales.

For independents evaluating whether to stock PetLabCo, that distinction changes the risk profile. A brand that earned its way onto PetSmart shelves through demonstrated retail sell-through is a safer placement than a brand that landed there following a capital raise. The former has already proven it can move product in a physical store, and the latter is still proving it.

Our read: the investment is the story, not the distribution

The PetSmart rollout is real, and 1,500 stores is meaningful distribution. But the news is that a private equity firm has backed the brand's brick-and-mortar expansion, and that makes this a different kind of distribution win than the pitch implies.

For store owners, what matters is whether PetLabCo's online customer base translates into foot traffic and repeat purchases at your counter. The brand has strong online ratings and a large claimed customer base, but those metrics measure a different buying behavior than the one that drives sales in an independent pet store. A customer who subscribes to a probiotic chew online and has it delivered every month is not the same customer who walks into your store, compares three brands on the shelf, and decides to try one.

The risk is that you stock PetLabCo based on its online success, and it sits because the brand's customers are already buying direct. The upside is that you catch the brand early in its retail expansion and benefit from any marketing spend supporting the PetSmart rollout.

What changes for independents who stock supplements

If you already carry two or three probiotic brands, adding PetLabCo now means you're placing a brand whose online customer base may recognize it on your shelf and switch their purchase behavior from subscription to in-store. It's worth testing if you have the margin and the shelf space, but give it a defined window and pull it if it doesn't move.

If you don't stock probiotics yet, PetLabCo is not the brand to start with. A rollout into PetSmart following a capital raise does not prove retail velocity, and you want your first probiotic SKU to be a brand that has already demonstrated it can sell in a store like yours. Stock a legacy brand with proven turn first, then add PetLabCo as a second or third option if you see customer demand for it.

For buyers at regional chains, the PetSmart rollout gives you a comp for evaluating other DTC supplement brands that pitch you. Ask whether the brand has retail velocity data from stores similar to yours, not online ratings. Ask whether they have a retail team that understands independent distribution, or whether they're pitching you the same way they pitch a mass retailer. And ask what their margin structure looks like, because a brand that built its business on DTC pricing often struggles to offer the margin an independent needs to make the sale worth making.

What we're watching

Whether PetLabCo's online customers follow the brand into physical retail, or whether the brand has to build a new customer base in-store. The former makes this a successful channel expansion, the latter makes it a reset. We'd also watch whether the firm funds a second wave of retail distribution into independents, or whether it treats PetSmart as the retail strategy and leaves the independent channel alone.
