(Virginia, Washington Metro area)
We have 2 young males who run vigorously in our fenced in back yard, roughly a quarter acre with a sloping hillside. They've torn up all the grass from their running, and we are now facing a sea of mud. Are there known solutions for the best ground cover to resist the result of their powerful activity? We also walk them several times a day and let them run around in an enclosed tennis court (this is rough on their pads, though). Any suggestions for how best to meet their excercise needs?
