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

Our ambition level is high, the opportunity is huge, & our love for dogs is through the roof! We launched in 2011 with BarkBox, a monthly-themed subscription of all-natural treats & clever toys. Since then, we've shipped more than 70 million toys & treats to the dogs across the world & use all of that direct customer feedback to inform new initiatives & ways to make magic between dogs & their people. Weve 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.
