AB Although the most intensively studied mammalian olfactory system is that of the mouse,in which olfactory chemical cues of one kind or another are detected in four differentnasal areas [the main olfactory epithelium (MOE), the septal organ (SO), Grüneberg’sganglion, and the sensory epithelium of the vomeronasal organ (VNO)], the extraordinarilysensitive olfactory system of the dog is also an important model that is increasingly used,for example in genomic studies of species evolution. Here we describe the topographyand extent of the main olfactory and vomeronasal sensory epithelia of the dog, and wereport finding no structures equivalent to the Grüneberg ganglion and SO of the mouse.Since we examined adults, newborns, and fetuses we conclude that these latter structuresare absent in dogs, possibly as the result of regression or involution. The absence ofa vomeronasal component based on VR2 receptors suggests that the VNO may beundergoing a similar involutionary process.
