Ric Flair is widely considered to be one of the greatest professional wrestlers of all time and has had a long and successful career in the industry. However, it is subjective to determine if he is the "top dog" or not. There are many wrestlers who have had successful careers and have been considered to be at the top of the industry at different points in time. Some may argue that wrestlers such as Hulk Hogan, Steve Austin, The Rock, or John Cena have also been considered the "top dog" at different points in their careers. Ultimately, it is up to personal interpretation and opinion to determine who the "top dog" is in the world of professional wrestling.
