We adopted Grace, a Miniature Schnauzer, about 3 years ago. The shelter thought she was about 3 years old. I thought it was great that she had no reaction to thunderstorms as our previous dog was terrified of them. All of a sudden, this year she is afraid of thunder, the noise of fireworks and even when a band plays at a nearby tavern (bass drum noise). She shakes, pants and basically tries to melt into my body. I basically just sit calmly and let her shake and drool all over me. I don't reprimand her or comfort her. Has anyone else had this happen where a dog suddenly becomes fearful of noises. I have racked my brain and cant think of anything different that would have set this off.
