Just an update on the staph infection after 10 days on medication: No Change. It's still just as bad. Took him back to the vet and we are now on a different medication, Cephaloxin (Amoxicillan), for the next 20 days. I was also told not to use any Tea Tree/Oatmeal shampoo but I was given a different medicated shampoo - Malaseb. Hope this all does the trick!
