Xerxes' uncle, Marshall Matt Dillon (Marsha, Marsha, Marsha) had an ischemic stroke last week and was put down in his home surrounded by those that loved him. He was almost 5 years old, was a dual champion (conformation and lure coursing) and even though he was red in color, he still had many many "blonde" moments-thus the call name.
Rest in Peace Marsha, there are plenty of rabbits to chase and your family will be waiting for you at the bridge.
