<p>Thank you for reaching out with your concern about your 12-year-old dog's unusual barking. It's understandable to be puzzled by this change in behavior, especially in an older dog.<br><br><br><br>There are a few possibilities for why your dog might be barking at nothing. As dogs age, they can experience cognitive changes similar to dementia in humans, which could lead to confusion or disorientation. It's also worth considering if your dog might be hearing or seeing something you cannot, as their senses can detect things we might miss. Another possibility is anxiety or changes in their environment that could be causing stress.<br><br><br><br>At home, try to provide a calm and comforting environment for your dog. Ensure they have a safe, quiet space where they feel secure. You might also find that engaging them in more interactive play or providing mental stimulation through puzzle toys can help reduce anxiety and keep their mind active.<br><br><br><br>Watch for any additional signs that may indicate a more serious issue, such as changes in appetite, sleep disturbances, unusual aggression, or if the barking becomes incessant. These could necessitate further investigation.<br><br><br><br>If these behaviors continue or you notice any concerning symptoms, I recommend booking a video consult with our Dial A Vet team. We can help assess your dog's needs more closely and provide tailored advice. Take care!</p>
