Why fireworks are hard on dogs
Fireworks are loud, sudden and unpredictable. They also come with flashes and smells, and they last a long time. Dogs cannot understand where the sound comes from or when it will stop. In the Treasure Valley they are not limited to one night, since neighborhoods set them off for days before and after the Fourth.
A frightened dog may pant, shake, hide, bark, destroy things or bolt. Bolting is the biggest danger. Dogs run through fences, doors and windows, and end up far from home. Many lost-pet reports spike around this holiday.
If your dog is also scared by storms, read thunderstorm fear and noise sensitivity. The skills overlap, but the timeline is different. With fireworks you know when the trouble is coming.
