To see dog poop in a dream represents a problem created by a loss of self-control over your instincts and urges. A situation that may require you to fix it or "clean it up." Problems created by sticking up for yourself too strongly. Excessive fighting with others to defend yourself that has created a much bigger problem. Feeling that you've "stepped in shit" with reckless or irresponsible behavior. Sexual behavior or infidelity that causes problems with new relationships if you get caught.
To dream of stepping in dog poop may reflect feelings about yourself carelessly creating a problem for yourself by not being responsible enough. Poor judgement that has resulted in an embarrassing problem that needs to be cleaned up respectably.
Dog poop is a sign that you need to be more careful, think more before you take action, and be more respectful towards others. A need to consider the consequences of enjoying yourself or proving yourself in a dangerous way.
Example: A man dreamed of seeing dog poop all over his house. In waking life his wife caught him watching pornography and he had to explain himself to her, through all the porn in the garbage, and prove to her for a very long time that he wasn't going to look at it again.
Example 2: A woman dreamed of smelling dog poop, but never seeing it. In waking life she was afraid that her sexual interests in a old romantic partner would create serious problems in her new relationship. The smell of dog poop in this case may have reflected her feelings about potentially "stepping in shit" by talking about her ex-lover to her new boyfriend.
