This Reddit thread from the r/unpopularopinion subreddit centers around the idea that it is not socially acceptable to express dislike or hatred for dogs. Many commenters share their personal experiences, including negative encounters with poorly trained dogs or aggressive dog owners, and explain why they have developed a dislike for dogs. However, these feelings are often met with negative reactions, leading to a double standard where criticizing dogs is considered unacceptable while criticizing other animals like cats is often accepted. Some users argue that the dislike for dogs stems from the actions of irresponsible owners, while others highlight the inherent unpredictability and potential danger of dogs. Overall, the discussion explores the complexities of animal ownership and the social stigma attached to expressing negative feelings about a popular pet.
