Some dogs will howl at any high pitched frequency because their ears are far more sensitive than human ears.
It depends on how you mean. They are not capable of telepathy, but wolves howl to locate other pack members and dogs howl too.
To make your mate stop following you all you have to do is howl and when your mate starts to howl then run away from him/her and they will stay put it if you are far away enough. Regards, Lunaressa WolfQuest

Loud enough to carry a mile or more on a still night! In terms of decibels, if you stand next to a howling wolf it's slightly quieter than a pneumatic drill - 90 to 100dB would be a rough estimate. (NB: I'm a volunteer at the UK Wolf Conservation Trust so frequently get to hear wolves howling).
