Medications can help increase the amount of protein that pets with shunts will tolerate, so it is important to combine nutrition and medical treatments to maximize the pet’s nutrition while minimizing symptoms. Depending on how severe the symptoms are and whether the shunt can be surgically corrected, it may be possible to slowly increase the amount of protein over time, even to the levels in normal diets.

The most frequently observed indications of the condition are such central nervous system signs as hyperactivity, disorientation, temporary blindness, and excessive salivation.
Can a portosystemic shunt lead to the liver?
