text: can there be any health effects of living in a house that has an overbearing smell of dog urine?   "the odor exposures that have received the greatest research attention are those that involve irritation. physiological responses to irritation in the upper respiratory trace (nose, larynx) and/or lower respiratory tract (trachea, bronchi, deep lung sites) have been documented in both humans and animals." http://www.pmac.net/am/sludge_excerpts.html i hope i haven't taken this out of context, but i'm sure it can't be good nonetheless. i lived in a rental that had this problem, and had to remove the carpeting and pad, spray the exposed floor with a water/bleach mixture, and allow it to dry before recovering with new carpet. best of luck!
