I can only go on what i was told by some one on guntrader that had one, He said it would just howl at home for no reason.
I did not know much about the breed although t have seen a couple and just asked someone who had one at the time i was looking for a new dog, very nice dogs that they are i decided not to risk owning a dog that had to spend 4 hrs a day in the kennel IF it was going to howl.
