ABOUT BARK

Here at BARK, we love dogs and their people. We’re looking to make all dogs happy throughout the entire world (we’re not kidding). Think Disney for dogs -- we make magic for dogs and their people through our products, events, and experiences.

Our ambition level is high, the opportunity is huge, and our love for dogs is through the roof! We launched in 2011 with BarkBox, a monthly-themed subscription of all-natural treats and clever toys. Since then, we've shipped more than 70 million toys and treats to the dogs across the world and use all of that direct customer feedback to inform new initiatives and ways to make magic between dogs and their people. We’ve since expanded into other offerings as well, as we aim to become THE Dog Company for every family with a four-legged, belly-scratch-loving, interspecies family member.
