Shar Pei
Shar Pei fever (also called familial Shar Pei fever or FSF) is a condition seen in Shar Pei characterized by recurring fever and swelling of the hocks. It is similar to familial Mediterranean fever in humans. The cause is unknown, but it is thought to be inherited. Shar Pei fever can result in renal and liver failure through accumulation of amyloid in those organs (amyloidosis).
