This thread is very old but yes, I have a screamer. Tango has the traditional, ear piercing, absoltuely awful to listen to Toller scream. Before I had her, I would've said that Jesse (my RB Dachsie) was a screamer too but she wasn't (she just had a horribly high pitched barky whine that sounded very close to a scream). Tango doesn't scream often though, fortunately.
