My name is***** and I am sorry to hear that Kodee is not doing well this morning.
First, was the liver cooked or raw? If it was raw, was it deep frozen first to kill any bacteria on it before feeding? Do you know the source of the liver? Grocery store or home-dressed?
Second, how is Kodee feeling this morning? Vomiting? Eating? What color was the urine- red or brown?
Based on your history of blood in the urine and very dark diarrhea (which could be bloody) I would strongly recommend taking him to the emergency room this morning.
Causes of blood in urine include bladder infection and bladder tumors. Causes of brown urine can include bilirubin (from liver failure), severe muscle damage and some toxins.
Causes of dark diarrhea or bloody diarrhea include food poisoning, eating something very irritating to the gut such as plants or garbage, parasites, and others.
Does this help? Do you have any other questions?
