I think it depends a lot on the density of the crowd.  Chihuahuas have become quite popular in the town where I work; Drammen, Norway, about 65k people. And they always seem to me to be quite oblivious to the difference in size between themselves and other dogs and humans.  Of course, we don&#x27;t have crowds in the same way that, say, London or New York has crowds so the risk of being stepped on is rather small (except during the World Cup Ski Sprint of course).
