Why does my senior dog ignore commands he used to know?

Age-related hearing decline often happens gradually enough that owners do not immediately recognize it, especially since dogs frequently compensate well using visual cues and routine for a surprisingly long time before the loss becomes properly obvious to anyone watching. A dog that no longer responds to a verbal come command from another room, but responds readily when you are in its line of sight, is showing a classic pattern of hearing decline rather than genuine disobedience, and this distinction matters enormously for how you train going forward.

A command like sit or down that was once effortless can become genuinely uncomfortable for a dog with hip or knee stiffness, leading to hesitation or reluctance that looks like ignoring the command but actually reflects real physical difficulty completing the requested movement smoothly. Watching whether your dog struggles specifically with certain commands involving particular movements offers a useful, practical clue here worth acting on.

Try giving a command while directly in your dog's line of sight, paired with a clear hand signal, to see whether response improves, which would point toward hearing as the primary factor at play. For commands involving specific physical movements, consider whether an easier variation, or simply not requiring that particular command as often, might suit your dog's current physical reality better than pushing through discomfort.
