I'm so sorry to hear about the loss of your dog. It's unlikely that pancreatitis results in acute liver failure/necrosis (ALN)- while pancreatitis can result in ELEVATED liver function tests (LFTs), it shouldn't cause failure. Cause for ALN include blue-green algae exposure (in stagnant ponds), sago palm ingestion, xylitol sugar-free gum, a few medications, etc. Sometimes end-stage liver disease (cirrhosis) can also cause acute liver failure also.
