it's pretty weird that it's only on one side.

i've had a cocker spaniel that had allegies but that was all over his body...........
i'd advise you to go to the vets. this could be neurological and all the ointment may only enhance the scratching. then you will be paying more money than if you go to the vets. maybe it's something small that is getting worse due to the treatments that your giving him now.dry winters shouldn't make a diffrence on his skin. you could try raw diet as this improves the skin and coat from the inside. sheep fat is also good for the skin. fish oil can do wonders and corn oil also works from the inside. but because it's on one side................
