Dirty Dogs
If people only shower so often (in the countryside, I finally learned this trip, sometimes people shower as seldom as a few times a year, and in the dead cold of winter, many do not shower) then you can only expect that the cleanliness of the pups is not a priority. Of course, in the city things are different, people tend to shower and sometimes have much greater access (ie private or in-home bathrooms) to showers than do countryside dwellers, and some, in the city also will take better care of their dogs (also note:this is Shangqiu, Henan, NOT Shanghai), but these pups are certainly an exception.
