For the last few days I’ve noticed this horrible smell off my dog. It isn’t a farty dog smell. He hasn’t rolled in anything. I’ve checked him all over and there are no cuts or anything clinging to him. The smell seems to be coming from his head but I can’t pinpoint where from exactly. It doesn’t appear to be from his mouth or ears. It’s just there. I can’t exactly describe other than to say it doesn’t smell healthy.
