The term 'dog attractor' can be broken down into two crossword solutions: SMELL (5 letters) and ODOR (4 letters). SMELL is the sense of detecting airborne molecules, usually through the nose. ODOR is a particular SMELL, often associated with something that has been left to decay or rot. Both SMELL and ODOR are important for dogs, as they rely on their sense of SMELL to detect food, potential mates, and other animals in their environment.
