The dog may have a combination of dark an light area on the basic coat. Cochleosaccular is the most common cause of deafness and is associated with coat color patterns. It is usually seen in dogs with the piebald color genes or merle color gene. It can cause deafness in either one or both ears and is seen more in association with blue eyes and a white coat
septum is present between the two ventricles and separates the oxygenated and deoxygenated blood. hence if it gets ruptured then the two blood will mix up. thanks
