Rash on neck and ear infection

hi I'm new to this my 18month old blue staffy has had a lot of problems recently has trouble with her ears and just wondering if anybody has used thornit ear powder I have been to vets a lot with her they do not know what the cause is I have tried all sorts get it back to normal then starts again

Hiya my boy also suffered but changing his diet helped. I do now use thornit. You could try some sudacream to help sooth any sore skin or ive half a piriton (not piriteze) once a day for a course. When you have a mo pop along and say hi here
