Portosystemic Shunt in Yorkshire Terriers
High Risk Category: Gastrointestinal Typical onset: Under 2 years (congenital) Hereditary: Yes Est. treatment cost: £3,000-£7,000
Portosystemic Shunt is one of the most frequently diagnosed conditions in the breed within the Yorkshire Terrier. Common indicators include stunted growth, neurological signs after eating (circling, head pressing), and seizures. A portosystemic shunt (PSS) is an abnormal blood vessel that allows blood from the gastrointestinal tract to bypass the liver, preventing detoxification. Toxins accumulate in the bloodstream causing hepatic encephalopathy. Congenital shunts are hereditary. It typically becomes apparent at Under 2 years (congenital). In smaller breeds like the Yorkshire Terrier, early detection and prompt treatment generally lead to better long-term outcomes. This condition has a hereditary component — prospective owners should request documentation of health screening from the breeder. Treatment costs are estimated at £3,000-£7,000, making comprehensive pet insurance a practical consideration.
