Good news, I went to the vet. Your not going to believe what it is! I had mentioned about the ear infection thinking it was an old yeast infection that had returned. I had been treating it but no change. Well it turns out that it was NOT a yeast infection! It was "bacterial" instead!
That bacterial infection turned into a "secondary" infection that spread to the rest of Scooby's body! So the skin is turning "black" after the unseen puss spot have burst and scabbed over. The hair then also falls out.
I had been treating his ears with alcohol or peroxide on occasion and it did seem to help a tad but was worried too much about continuing that route so I stopped. Turns out that may have been the good home treatment.
The doctor gave Scooby a shot of hydrocortozone for the inflamation/itching. I got antibiotics and must clean/treat his ears twice a day. It's going to take atleast 2 weeks to clean up the infection. Then he has to go back and possibly have earwax removed. Although I think I can do that myself. My other dog had that same issue without the infection.
Thanks for your help! I am soo glad it wasn't the mange! Although I believe I am getting a little "itchy". Now let's hope I can get Scooby to stop trying to eat the ferret!
