Benzodiazepines and other sedatives should not be administered. Food should be withheld until neurologic status improves.
What can I feed my dog with hepatic encephalopathy?
Dogs with hepatic encephalopathy should eat a diet with a reduced amount of protein since the byproducts of protein digestion (e.g., ammonia) are responsible for many of the symptoms associated with the disease. Diets should contain just enough protein but no “extra” to ease the liver’s workload.
Is liver failure in dogs reversible?
It is not reversible . Before the liver reaches this terminal stage, it can recover from damage and heal itself to the point where your dog has normal liver function. This is possible if proper treatment is instituted early on; the extent of recovery depends on the exact cause of the liver damage.
Can antibiotics cause liver failure in dogs?

What foods increase ammonia levels?
Ammonia levels increased with increased dietary protein intake and with decreased liver function. For simulations of a liver without disease, increasing protein consumption from the recommended protein intake to the high protein diet increased ammonia levels by roughly 59%.
Does encephalopathy go away?
