Melanoma is a type of cancer that affects the skin and is the most common form of cancer in dogs. It can occur in any dog, but it’s most commonly seen in black dogs, especially those with light-colored fur.
The risk factors for melanoma are similar to those for humans—sun exposure and tanning beds, as well as genetics. The most common cause for melanoma in dogs is an increased sensitivity to UV radiation from sunlight or artificial sources (such as tanning beds).
Melanoma can be treated with surgery, chemotherapy, or radiation. If your dog has melanoma and it’s not spreading around their body, your veterinarian may recommend surgery to remove the tumor. If your dog’s tumor has spread to other parts of their body, chemotherapy or radiation may be recommended instead of surgery.
