This is Maverick, our company mascot and beloved member of the family. He was found walking along a highway in southern Illinois. He was taken to a shelter that keeps dogs for a short time to see if anyone claims them, and if not, they are put down. Prior to putting him down they put the word out to non-kill shelters to see if they had room. A shelter in Joliet, Illinois was able to take him in. This is where we found Maverick, the coolest member of our family.
