I'm going to complain about/call the cops on my neighbor's barking dog
Is it a really big deal?
I'm afraid I will get bit if they get loose.
You should not have to listen to a barking dog all day. People should be considerate when getting pets that may be dangerous.
Right. If he can't control his animals, then I'll make the cops force hem to.
That may be your only option. From the sounds of it, it is only a matter of time before a dog attack happens if things sand where they are.
