The Lactulose helps, but with MVD and Liver Shunt, some part of the liver is still functioning on it's own. The liver can also rejuvenate, so there may come a time when the dog can handle a lower protein/ hepatic diet on it's own. All depends on the extent of any permanent liver damage. Also an FYI: A dog can live and do well with just 1/4 of it's liver functioning normally.

Lactulose - Pet, Dog and Cat Medication and Prescription List | petMD How It Works
When your pet takes lactulose, the syrup travels through their digestive tract without being absorbed. There, bacteria can break it down which makes the intestines more acidic. The acidity draws water into the intestine, loosening the stool. These acids also convert toxic ammonia in the colon into ammonium, which is then passed in the stool.
Side Effects and Drug Reactions
Lactulose may result in these side effects:
Bloated belly
