G-Diddy,

I sympathize 100%. I wish I knew what would help you with Gracie. I'd be willing to bet that someone did throw a firecracker
or other loud device very near to her while she was outside.

If she didn't see the person, I would think it would scare her
all the more. My dog Smokey just recently overcame a fear of
t-storms & thunder, only to be scared witless all over again by
the setting off of fireworks in the neighborhood every night last
week. He had always loved going outside before, but now will
only go outside if I put on his leash & drag him out AND stay with
him the whole time. His little legs literally shake with fear.

I'm think if this goes on much longer(no fireworks last 2 nights)
but he's still scared to go outside) that I'm going to make an appointment with the dog trainer to see what I can do to help him overcome this new fear. I wish you luck & patience to help
Gracie.
