What causes a painful, crusty, oozing spot on my dog's ear?

Updated On September 23rd, 2025

I’m wondering what a small crusty spot on inside tip of black lab ear may be? Seems to ooze/crust and not heal for many weeks and is very painful when we try to examine it. She also has an area on front leg with flaky skin and loss of hair for months (far left in pic is a scar); I don’t think the two are related, but not sure??

Thank you for submitting your question regarding your dog. I recommend that she sees her veterinarian. The ear could have a small mass that has now become infected. The leg appears to have an elbow callus. Her veterinarian will determine if this is the case. If a mass is present on the ear, it may require surgical removal. If it is a wound, then antibiotics could be needed. If the limb has a callus, treatment is generally not required. I hope this information helps!
