Possible causes
A multitude of issues can cause a dog’s bark to change.
Risk factors
Symptoms vary based on the underlying cause. A change in bark resulting from transient issues such as overuse, smoke inhalation, and laryngitis is likely to be the only symptom and may improve quickly without treatment. When changes are related to hypothyroidism, bacterial infection, or injury, the symptom is expected to resolve once the underlying condition is treated. Vocal changes associated with degenerative myelopathy, brachycephalic airway syndrome, or dysautonomia may cause a dog’s bark to be permanently altered.
A change in bark as an isolated symptom is associated with more benign conditions. More serious conditions that might show a change in bark typically also have other more dramatic symptoms. Examination by a veterinary professional is warranted in either case.
Testing and diagnosis
An oral and physical exam along with a detailed history are important first steps in diagnosing changes in the bark. More specific diagnostics may be indicated if symptoms and physical exam suggest there is an underlying condition.
Treatment and recovery time vary greatly depending on the underlying disease process. Benign causes such as overuse may require nothing more than rest and recovery is quick. Cases that have more severe underlying causes, like IVDD, may require surgery, medications, and a long recovery period.
Similar symptoms
