Dogs barking with the Azaan

Q: There are 6-7 masjids in our area from where we easily hear the azan. One thing that is bothering is that as soon as muazzin of masjid 'A' starts calling azan, the dogs of this locality start barking. It happens 5 times a day, and only when muazzin of masjid 'A' calls azan. If muazzan is not there and some other person comes to masjid 'A' to call azan, then dogs do not bark. some people of locality say that this muazzan should be changed, others say these dogs must be thrown away. What could be the correct thing to do?
