Hi
I had a different kind of problem !!
everytime the crackers would go "bang" Joshua would come to the balcony and bark his head off .. his constant barking was worse than the cracker sound !! I just coudnt stop him from barking .. keeping the balcony door closed didnt help as he stood near the bedroom window, managed to put his head out of the grill and continued to bark
( and ofcourse I had to put with all the complaints from the neighbours :
cheers
Bhooma
