I will look into it tomorrow mate, my sister has just had her dog treated with steroids and 2 different sorts of antibiotics that didn't work, the vet said there's a 3rd option if that didn't work then she was going to need to look deeper into the situation. The 3rd sort along with the steroids worked. That's in a old spaniel. He's ears fcuking stunk and you were barley able to touch them without him screaming the place down.
