we have them from september till xmas,,,not every night but most nights,,then of course theres new years eve,,and new years day,,,oh then we got easter,,,ANY excuse they let them off,this year they will get a firework stuffed very securely up their back passage,,luckily our dogs dont batt an eyelid,,sleep through them normally,and indoors we always leave the tv or radio on,,we cant even get the dogs in when they going off,they will not move,,lol,,,but really is there any need at all to let them off all bl00dy year round,,,
