My old dog has a thickened ear sore. Is it serious? Should I biopsy?

Question

My 10 year old beagle mix has had this sore on his ear for nearly a year. He’s scratched it a lot which caused it to bleed a few times. It’s finally scabbed over and he’s left it alone, however it’s thickened and still present. Is this something suspicious and worth having biopsied?

This looks like a wart or benign mass from the photo. Usually malignant tumors grow more quickly, and are not as well defined as this. The only way to know for sure though is a biopsy. If he continues to irritate the growth then certainly I would have it removed and biopsied. If you wish to monitor it I recommend taking a photo and measuring it at least monthly so you’ll know it it starts to grow or become more inflamed.
