Slim is a member of the Adventupups litter.
He belongs to Chad Schouweiler (traded for Biggie), but is with the BraverMountain team for the 2018-2019 season. As it turns out, Slim is back with BraverMountain for good. Chad thought Slim had a gait more suited to longer distance running, so he's back home with his siblings.
As the pups have turned to yearlings, Blair did threads reintroducing these brawny, enthusiastic teenagers. Here is her thread on Slim.
As a two year old, Slim is full team member and thriving at BraverMountain.
