MariaM,

You can get Benadryl at any drugstore, but I wouldn't give it
to Major without first asking your Vet about it. It's given by your
dog's weight & only the Vet knows if he should have it.

Smokey, unlike my previous dog Buddy, is very afraid of
fireworks & loud noises. Last night I had had enough of a
neighbor boy setting them off at all hours and I called the police.
There is a non-emergency number (not 911) that can be called
for things like this. The police came within an hour & took my
complaint. They will make frequent trips through the area & keep
a check on this problem. Believe it or not, the guy quit setting
them off & all's peaceful & quiet again.
It's not fair to Major(or Smokey) to have to put up with some
jerky kid's idea of fun.
