Here are some general signs that could indicate an infection in a dog's whiskers, but it is crucial to consult a vet for a proper diagnosis:
* Redness, swelling, or irritation around the whiskers: This could indicate inflammation or infection.
* Discharge from the whiskers: This could be pus, blood, or other fluids, depending on the cause of the infection.
* Loss of whiskers: This could be a sign of damage or trauma, but also a symptom of some infections.
* The dog pawing at the area: This could be a sign of discomfort or itching.
* Behavioral changes: The dog may become lethargic, lose appetite, or seem more sensitive to touch.
Remember, these are just general signs, and only a veterinarian can properly diagnose and treat any issues.
