Out here on the farm, the old dogs tend to sit on the porch or lay under the trees and watch the world go by. Sometimes they get up and stroll over to the creek and get themselves a drink, but their main job is keeping the young dogs in line and making sure they do the things that young dogs are supposed to do like chase the deer out of the garden and the hay fields and make sure no racoons get into the chickens or the feed bins. They are the teachers in the barn yard.
Every now and then, an old dog has to get off his lazy ass and rise to the occasion. Such a time is when a couple unknown dogs approach the farm. It's usually the old dogs who take off in a run to intercept and keep these dog out of their territory. Usually they are mangy, sickly looking old strays. Sometimes they are looking for a fight, but they aren't really a match for the well fed, smart and insanely loyal old dogs I've got under my trees.
It's always good to be able to rely on an old dog to draw that line in the sand and attack anything that tries to cross it.
Go git em Joe.
