My dog's bark changed. Is a different bark a serious health issue?

Hi, I have a dog who is 9 years old and never showed signs of any illness. However, on this day, his bark sounded very different than any other usual day. I am concerned about what the problem could be, but I wanted to get any medical advice on if this could be a serious issue or something that I shouldn't be concerned about?

Any change in voice can be very concerning. I have seen throat abscesses, throat tumors, chest tumors, and even thyroid disease cause changes in voice. Some of these can be life threatening. I would not wait on this and would encourage you to have him evaluated by your veterinarian as soon as possible. They may recommend an x-ray and possibly a sedated pharyngeal exam (back of throat). Best of luck and thank you for using Pet Coach.
