My dog has a black spot on its ear. Is it cancer or normal?
Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. It is possible that this spot is part of Honey Boy's normal pigmentation of his skin. If you believe that this spot has appeared rapidly or suddenly, and if it is changing in size or appearance, I recommend making an appointment with your veterinarian to have it examined. Otherwise, you can monitor the spot over time and look for changes. Pigmented areas on the skin can be benign, but unfortunately, they could also indicate malignant forms of cancer, such as melanoma. Your veterinarian will be able to examine the area, and can take a biopsy of the site to send for histopathology to determine what cell types are present. I hope this is helpful!
