Okay, I noticed it often now a days.. whenever Imam starts azan for faraz prayer some dogs start barking together.. This is happening so often but not exactly daily. But they start barking exactly when imam starts the azan..

Is there any interpretation behind this? Does anybody else got into similar experience?

**Update:** I just noticed it happens every day. And they actually do not bark but just make a sound (that sounds like crying/ howling)..
