Like your dog, when they are howling at coyotes it typically starts as barking and changes to a mournful sound, followed by a few more barks and more howling. It's how you would imagine a wolf I suppose. An ar ar arroooooo. For sirens and trains, it's a high pitched whiny sound to match the wailing of a siren. When they're bored, it's typically low and drawn out but it varies.Does it sound higher pitch like bantam rooster's crows?
