There are 4-5 deer that wander around our neighborhood (including two adorable fawns), and every time they appear near the house, Violet and Gus give them what-for, barkwise. From a canine point of view, it’s just not OK for large, reddish-tan ungulates to be out there. Ever. The other dogs in the neighborhood all have pretty much the same attitude, but the barking isn’t a problem in terms of noise, because all the homes here are on 5 acres at least, so the dogs are distributed over a fairly wide area.
I’m convinced, though, that you could track the movements of our deer band by plotting the barking as it comes drifting through the trees throughout the day. At 11 a.m., barking from north northwest indicates the deer are over at so-and-so’s house; an hour later, barking from west southwest reveals the deer have crossed the road and are at such-and-such’s. The next morning, the deer are obviously over at a third neighbor’s because his dogs are barking like crazy.
Maybe such a study would reveal some heretofore unknown insight into the movements of deer. Maybe some natural history student should do a dissertation on the subject. On the other hand, maybe it’s just useless information provided by bored dogs who should be minding their own business.
