I am sorry to hear about Jake. He appears to have a tumor here on his ankle. We can have benign (meaning they don't spread elsewhere in the body and cause more cancer) tumors as well as malignant (meaning the tumor is aggressive and can spread) tumors in dogs. There is no way to tell for certain just by looking at a tumor what type it is. An aspirate with a needle can sometimes provide information on what type of tumor we are dealing with. The location of this tumor, however, in may opinion would warrant surgical removal because it is an area that could easily be traumatized/get injured, and it is also an area without alot of extra skin for closing a surgical site, so it is best to remove tumors in these locations before they get too big!
