I say nights, because we had fireworks going of last night and will no doubt have them on Sunday.
Our Bella is doing ok, when we got her 8 years ago this January. At the puppy class they gave us a cd,with noises on like loud cars,drills and fireworks etc. We had to play this very low hardly audible to us and it has worked.
Both our Lassie dogs used shake with fear, our Tess run upstairs and got in the wardrobe.
