Sick Dog

I have a two year old rottweiler that is loosing an alarming amount of weight. My vet can not help me, he has taken blood and done test to no avail and I simply cannot afford to do any more test, It would be different if we were getting somewhere but we are not. so I thought I would ask the world for any asistance in locating a newsgroup or web site that might help me out, something like ASK THE VET or whatever. Ive done searches but cant find any . So if you have any information that could help my beloved Sadie It would be thankfull.

Thank you Wayne and Sadie
