afraid of big dogs barking

So, my little guy Murray freaks whenever my adult dogs start barking at some thing. Murray will run for cover and try to hide when they bark. He does the same thing outside when he hears dogs barking in the neighborhood.

Any ideas on how to help him over come this fear?

How old is Murray?

Okay. Just looked up your other posts

He's still a baby and new to you.

For now, I'd ignore it -- don't reinforce it by acknowledging it. See if his natural curiosity doesn't take car of it in a few weeks

Thanks for the reply. He is curious about the barking. Today instead running he sat and listened to them. Before he'd run to his crate or try to squeeze between the wall and the couch.

It just takes a little time for him to figure them out. At first, how's a pup to know they aren't after him?
