I am visiting family for the holidays. One of the relatives has brought a dog that lays on the couch and barks whenever I come within, say, 10 feet of it. (For example, let's say I'm looking for the remote control or just wish to sit on the couch.) The dog behaves aggressively and barks loudly as if it were defending its territory (the couch).
My question is, how should I behave towards this dog? Specifically, should I make eye contact or avoid it? Should I let the dog have its space and stay away? Should I retreat when the dog barks at me or stand my ground?
