Early Symptoms of Dog Melanoma: What to Watch For

Section 1: Symptoms of Canine Melanoma

Malignancy levels in canine melanoma vary depending on the location of occurrence. Melanomas found on the skin and eyes are generally less aggressive, while those on the paws have a 60% malignancy rate, and those in the mouth are the most aggressive. Melanomas can be either malignant or benign. These tumors often have a darker coloration or lack pigmentation. Benign melanomas are more common, but malignant melanomas pose a more serious concern due to their rapid growth and high risk of organ metastasis.

Malignant melanoma is most commonly found on the lips and nail beds in dogs. Certain breeds, such as Miniature Schnauzers, Standard Schnauzers, and Scottish Terriers, are more prone to melanoma, and males seem to be more susceptible than females. Malignant melanoma appears as a raised bump, often with ulcers, and can manifest as gray or pink masses in the mouth. On the nail beds, malignant melanoma presents as toe swelling, which may lead to nail loss and destruction of the lower limb bones. Typically, nail bed and paw pad tumors can lead to secondary infections, making them difficult to diagnose.

Section 2: Treatment Options for Melanoma

1. Due to the rapid spread of malignant melanoma, treatment can be challenging. Current recommended treatments include:

2. Surgical removal of the tumor and surrounding melanoma tissue, which may involve amputation of the toe or even the upper and lower jaws;

3. Chemotherapy;

4. Radiation therapy.

When malignant lesions metastasize to other parts of the body, treatment becomes significantly more difficult.
