My 11 year old dog keeps on biting and licking his hind leg. He is eating fine. Everything ok. He runs around, gets excited. Normal all the way. can anyone explain what this is in his skin? It is kind of rough/hard to touch and there is a black thing on the top.

Poor Miggy! That lesion on his skin could be due to many things including a bacterial infection, east infection, allergies or flea bites. You need to protect the area from licking as this will make it worse. Have him wear an Elizabethan collar at all times. You can wash the area with soap and rinse it well once a day. If the area does not start looking significantly better in one week or if it looks worse at any point, have him seen by his veterinarian. Best of luck and please feel free to post any additional questions.
