The CADE will hold a public hearing this Friday, October 17, to evaluate the merger between Petz and Cobasi. Separately, the two chains still compete block by block — fighting for the same urban, high-income clientele — while facing pressure from major suppliers such as Royal Canin, Mars, and Purina. Together, they would form a network of over 500 stores, integrated logistics centers, and unprecedented bargaining power with suppliers.
The defence insists the market is “large and fragmented”: 60% of sales still come from independent pet shops. Yet something deeper is underway — digital, data-driven and inevitable. The merger is not territorial but informational. Petz and Cobasi would operate with a unified CRM and a data base covering nearly all urban Brazil. Competition would no longer hinge on how many players exist, but on who controls information and loyalty flows. The small shop still lives off its relationship with the pet owner; the giants will live off the consumer’s behaviour.
The case marks an inflection in Brazil’s antitrust policy. The deal builds the embryo of a data-and-logistics platform that goes far beyond pet food. A single app could integrate vet appointments, subscription plans and personalised offers, combining artificial intelligence with physical reach. Every purchase, visit and click would feed a proprietary prediction engine.
It is the birth of a super-retailer, not a classical duopoly but a closed ecosystem. Suppliers risk becoming logistical dependents; smaller retailers, peripheral service providers. And with millions of affluent, data-tracked customers, Petz–Cobasi could expand into life adjacency — insurance, wellness and home-care services. What begins as a merger of megastores could soon become the Amazon of animal well-being — with one twist: this time, the customer wags the tail thinking they’re in charge.
