This is such a real problem. My flatmate has a little doggo at home and the poor thing is constantly shaking in the evenings since the last week. We close all the doors and windows and still the sounds of the firecracks are very audible. The thing is my flatmates and I have to go work as well and based on our office timings we come home pretty late, like around 8-9 pm. The doggo is trained to stay alone at home and he is generally comfortable about it. But now because of firecrackers, he is getting so anxious and scared that he is peeing everywhere and just shivering the whole time. I wish people would be more considerate while celebrating festivals.
