Sierra can sleep through thunder storms, gun shots, fireworks etc.
But Buddy... Is DEATHLY afraid of loud noises.
To the point that I have to put him in his crate and turn the radio on loud, or he'll hurt himself.
He'll run and jump on the door to get outside, or if he's outside, he'll try to jump over the fence to run away!??! It is heartbreaking to see.
I get Tranquilizers for the 4th of July every year. BIG rule in my yard is No Fireworks!!

I'm sure it has everything to do with the fact that he was dumped in the woods and lived there for a few months with little or no shelter.
Poor baby boy...
