Jack is a Border Collie who used to work on a farm. It unfortunately lost too much money and every animal was being sold. He didn't want to deal with being given to a new family and just ran away from home. Pinokuni is a Cockapoo who got separated from his owner after a bunch of unfortunate events. Eventually he ended up running into Jack and the two have been tag teaming the streets ever since. Due to their stressful backstories, they attempt to live carefree lives. A lot of the time, Jack picks Pinokuni up by his scarf when they're running traveling or running from dog catchers. Mainly because Jack is hella good at leaping over things like fences and scaling trees. There's probably a bunch of videos on the web of people who filmed him climbing up a tree.
