diarrea-skinny

[gracie'smom]

Our two yr old Aussie mix has had diarrea-pancake batter for months. The Veterinarian has ruled out parasites and anything in blood tests. She has gotten bony and now aggressive when she eats-leading me to consider putting her down. I keep thinking a enzmye or probiotic may help her absorb nutrients. Doctor gave her many meds no result. Not sure how much I can spend in further tests especially since she is getting so aggressive. DO I see another Veterinarian, order expensive supplements? Tried many foods, now have her on a rice diet. She prioalso eats anything-stuffing from toys, plays with rocks in her mouth. Other than her thin appearance, she is still active with her ball, etc. She was the runt of her litter, only 32 lbs. Trainers say her agressiveness can be trained away- Is there another test to see if its cancer that isn't $$$. No vomiting or fever or bloody stools. DO I give up? I'd give her up for adoption to a trainer skilled person but was hoping to cure her medically first.
