Portosystemic shunts divert blood away from the liver, causing hepatic encephalopathy, growth retardation, and urinary tract problems in affected dogs, with surgical correction offering good welfare outcomes.
Dogs with portosystemic shunts experience chronic welfare compromise from hepatic encephalopathy and metabolic disturbance. Neurological episodes including apparent blindness, circling, head pressing, and seizures are distressing for affected dogs and unpredictable in their occurrence. The metabolic toxemia from impaired liver function causes chronic nausea, reduced appetite, and stunted growth. Urate bladder stones cause urinary pain and obstruction that adds to the welfare burden. The condition often goes undiagnosed for months as signs may be subtle or episodic. With timely surgical correction, welfare outcomes can be excellent, making early diagnosis and intervention critically important.
