We can kind of get our dogs to "howl on command." lol... a while back when Rosie was a puppy, we had an alarm system at our house. We checked it monthly. My brother would always say, "READY?" right before pressing the button to make the alarm go off. So, he'd say, "READY?", then the system would go "BEEEEEEEEEEEEEEEEP!!!!!" And then the siren that was installed under our front porch would go off. Rosie would start howling, every time at this. And she got the other dogs started up, too. So now, all we have to say is: Ready? Beeeeeeeeeeeeep! (And then make a siren sound.) ---- And that makes her howl, which makes Zoe howl, Bart bark and Molly *try* to howl. lol.
