Editors often complain about too much exposition, generally referring to too much backstory and setting descriptions. However, there is a fine line between too little and too much backstory. The exact level needed will depend on a combination of factors: your narrative style, perspectives used, type of scenes, genre and previous story history (i.e. series). If something directly relates to your character’s motivations and actions, then it should be included in some fashion, but that tidbit about a character growing up surrounded by dogs might be irrelevant, depending on the story.
