The reason for the predilection is unknown. Ideas proposed include it being hereditary [22] or environmental. [23] The Labrador Retriever also shows a predisposition to other hepatobiliary diseases, including: reactive hepatitis, nodular hyperplasia, and gall bladder disease. [21] A UK study found the breed's average life expectancy to be 13.1 ...
