If you're concerned about a dog's bleeding whiskers, it's important to consult a veterinarian. There could be several reasons for this, including:
* Injury: The whiskers could have been accidentally cut or snagged on something.
* Infection: An infection around the whisker follicle could cause inflammation and bleeding.
* Parasites: Mites or other parasites could be causing irritation and bleeding.
* Underlying medical condition: Certain medical conditions, like clotting disorders or immune system problems, can make bleeding more likely.
A vet can examine the dog and determine the cause of the bleeding, and recommend the appropriate treatment.
