Whenever a car drives past our house (It's a main road) My puppy (4 months) starts barking. Same when someone walks past on the sidewalk. It is getting very annoying! How can i stop her? Also she howls along to the fire truck/police siren! The neighbours have actually come over and told us to shut the dog up. Any ideas to keep her quiet? She even barks at the neighbours talking. Plz don't suggest giving her away because i love her.
