Does anyone have any tips/suggestions to help our dog's dry skin issues? The weather here has changed, it's cold outside equaling dry air inside. Our 90 lb Lab mix has been very itchy ever since the weather changed and he's up to date on his flea treatments, etc...so we know it's not that (plus it's too cold for fleas here now anyways.) He just seems uncomfortable most of the time...but otherwise is fine. He doesn't get baths...so that's not a contributing factor either. Any suggestions?
