Anyone who has ever lived next to someone with a barking dog knows how the spikes of adrenaline at random times of the day and night can raise stress levels significantly.
Living in southern California, I don't think I've ever lived anywhere where there wasn't at least one annoying dog. This includes everything from apartments, condos to single family housing. I just hate it. I wish designated dog free neighborhoods was a thing.
Last night, after the kids got to sleep, I saw my friends stack of mail and right on the top was a weekly mailer. The very top advertisement on the flyer was for a weekly dog poop pick up service. They'll come by your place once a week to pick up Scruffy's poop and deodorize the yard.
My point here: There are so many dog owners who should not own dogs.
