Quick answer: Many older dogs gradually lose hearing as nerves in the inner ear age. Signs include not responding to their name, sleeping through noises, startling easily, and barking more loudly. A vet should check for treatable causes like ear infections or wax buildup. Deaf dogs adapt well, especially when owners switch to hand signals, vibration, and light cues.
