Congenital deafness in dogs is a genetic condition that has a few different causes. In some dogs, it is associated with the piebald or merle genes. Dogs with this mutation experience degeneration of parts of the inner ear that are necessary for hearing due to the lack of coloration in their ears. In others, it results from hair cell loss in the inner ear.
