I know this is not a dog forum but I know many goat owners have dogs and probably the same problem. My friends dog has started hollowing if you touched his ear. He ask me to look at it and I did. The dog had 3 tick in ear that I removed. I swabbed it out and black stuff was in it. I wash it out woth hydrogen peroxide and applied some olive oil in both ears. I did the same to both ears. Where the ticks were I sprayed a little bluekote. Should I give him a shot of LA 200 today and maybe another Tuesday evening. He is still touch about that ear just after the application of medicines. I see how he is doing in the morning. Advice please.
