Our Story

PupWalkr was started out of necessity. Alex and I worked long hours, had dogs, and needed a way to take them out. You ever seen what an apartment looks like after two 70 lbs dogs have been in it for 12 hrs straight? That stuff changes a man. 

At the time, all other companies on the market were incredibly outdated. So we made our own. 

With us you can book online. Cancel when you want to. No penalty fee. And super awesome dog Walkrs. We think it's pretty neat.
