A new survey of dog owners shows that the vast majority of them look to their dogs when considering who to date. According to the dog-walking app Wag, 77% of people agree that how their pet reacts to a new love interest is very important. Most people don't listen to their parents or to a friend's dating advice. Although, 55% say that if their dog isn't happy with someone, that's a deal killer. About a fourth of people who say they dated someone despite their dog's negative reaction say they would "never make that mistake again."
