You're probably quite right about living in the country. I live in a remote area where there are no sounds of traffic or people going by so have to be extra observant of socialising puppie to such things. I use a CD of traffic noises etc. when they are babies On the other hand there are lots of noises here that they don't get in towns so it can work both ways. One of my dogs got spooked at a show by the noise of an ice cream maker starting up!
