Cold Sores in Dogs

Just like humans, cold sores also occasionally occur in dogs. Canine cold sores differ from human cold sores however, as they can be the result of many different conditions. They may be referred to as granulomas, granuloma complex or rodent ulcers.

  1. Symptoms

    • Red, sore, inflamed lesions on the dog's skin typically at the lips or nose are symptoms of cold sores in dogs. The dog may spend lots of time licking the area, and the sores may or may not produce discharge.

    Causes

    • Causes range from allergies, bacterial or viral infection, or skin irritants.

    Diagnosis

    • Your veterinarian will perform a thorough physical examination, followed by specialized tests. These may include bloodwork or swabs of the lesion-affected areas to determine the cause and best treatment for the lesions.

    Treatment

    • Depending on the cause of the sores, treatment may include topical creams or ointments, antibiotics, steroids, dietary changes and supplements, and possible surgical removal of any growths.

    Considerations

    • Treatment for cold sore-like lesions may take up to two to three months, but under proper veterinary care successful treatment is possible.
