Dear "leg2123" I have read this posting about your 2 year old male (dog I am assuming) who has been vomiting and having bloody diarrhea with dilated pupils and low energy for the past 36 hours. I understand that he has experienced these problems over Thanksgiving weekend of 2009 and he was treated with Kaopectate, bland diet and Pedialyte and that he responded to this treatment but no diagnosis was ever made except he may have had high liver enzymes. You are asking for advice on home care over the weekend.
It is very difficult to give advice without examining a pet under these circumstances. I would want to know if he has a fever, seems dehydrated, hurts when his belly is felt, etc. Without this information it is hard to give much information of what is causing his problems. He could have an infection, liver or other organ problem, intestinal parasites, or a large number of other problems.
As far as treating him at home, I would recommend giving him Pepcid AC (10 mg famotidine). You can give the Original Strength Pepcid AC 10 mg tablets if he is between 10-40 pounds, and Maximum Strength Pepcid (20 mg famotidine) if he is over 40 pounds. Give the tablet once a day. Offer bland food only if he stops vomiting.
If he continues to vomit, he will need to be taken to an emergency veterinary hospital. If you need help finding an emergency vet, you can look at this web site http://veccs.org/hospital_directory.php
