This needs to be qualified: “There are too many pets … for people who dislike dogs so much they can’t enjoy green spaces, cafes and other public areas.” rewilder

As I get older, I find myself questioning pet ownership. A pet exists for the sole purpose of pleasing its owner, giving it comfort, pleasure and companionship but also putting it at risk of abuse, pain, displeasure and abandonment. They are bred (often conforming to a human-designed ideal) or captured in order to perform human-pleasing duties. So, yes, there are too many pets for their human masters. 02Dscythe
