What it is
This is an inherited disorder of the inner ear caused by a genetic mutation, commonly known as DINGS1. It affects both the auditory system, which processes sound, and the vestibular system, which is the organ responsible for balance. The mutation prevents the normal development of sensory hair cells in the ear, leading to hearing loss on one side and coordination issues.
How it presents
Symptoms typically become noticeable during early puppyhood as the dog begins to explore. Owners may observe a persistent head tilt, unsteadiness or wobbling while walking, and a failure to react to sounds on one side of their head.
Treatment
While there is no cure, the condition is non-progressive and affected dogs can live high-quality lives with environmental safety adjustments and training. Lifetime management and supportive care costs generally range from 200 to 1200 EUR.
