Miss Daisy lets us know shes hearing sirens. She always howls at the sound of them. It could be a fire engine or police car it doesn't matter. She also howls at the ice cream truck. It's cute until we try to watch TV. She will hear the sirens on the television and guess what? She will howl at them too. It's just hard to watch a show that has sirens. Scooby doesn't seem to care about the noise he just reacts to Daisy howls. Do your dogs do this?
