My little mouse began to bark for no apparent trigger to when I was not at home or when the doorbell rings or when someone walks past the door or or. It remains for 18 months almost daily for 2 to 7 hours alone and it has never really interested, if there was something going on. About 4 months ago the barking went. I tried to get used to her all the barking again, it has brought nothing, except that the barking went off only after 15 to 30 minutes.
So I have myself wrestled me by an anti-bark collar to buy and annoyed now that I have not bought earlier. The small very quickly (after 3 days) understood that the Spühstoß has the same meaning as the signal "rest". I can only recommend this anti-bark collar.
