ok, I will close this thread. Anyone coming into this now will need to sort out all the who-said-what-to-whom when, and what they were responding to and so on.
Many good points were made, but kindly read over the posts by Mabsoot and Um Muhammad. If anyone has more to say about the hadeeth originally posted, or questions on dog saliva being najis, start a fresh thread, in shaa Allah.
