For decades, Petco has been a staple in pet care. Not only does Petco sell pet food and supplies, but it's also branched out into training, grooming, and veterinary care to help provide pet owners with everything they need for pet health and wellness.

In some ways, being multichannel is part of Petco's history. It started as a mail-order veterinary supply company at its founding in 1965 - and didn't open its first brick-and-mortar store until 1976.

While modern omnichannel shopping experiences are a far cry from 1970s-era mail-order shopping, Petco knows it needs to constantly evolve to meet the needs of remote customers.
