It was more than a year ago I wrote what I intended to be a playful column about a world without dogs. Some folks didn’t consider it amusing and probably still hate me for it. While I was only joking about this fictitious world without dogs, there’s no doubt such a world would be free of so many dog-related hassles.We wouldn’t have to worry about the out-of-control stray dog population which leads to euthanizing so many unwanted animals.We wouldn’t have to worry about getting attacked or bitten by dogs while on a friendly jog.
