fireworks season, neighbour's dog shaking all night

Every year it's the same. The soi next to mine has a wedding almost every weekend and the fireworks start around 9 pm. Last Saturday the neighbours golden dog (not mine, I just look after him sometimes) was shaking under my bed for 3 hours. What helped was closing the windows and turning on the fan so he cannot hear the bang as clear. Also I put a towel over his crate. A cheap tip but it really works for him. I keep a box of treats in the drawer now. Some dogs are fine with them, some not. Ask the owner first if you can. The rain season is also a problem for thunder. Same ideas work.
