Blue may have a chronic tooth root abscess or a sinus abscess which is causing inflammation in his upper airways and causes mucus production and at the same time may drain into his mouth causing the smelly breath. Please take Blue to your veterinarian for an exam. The vet will closely inspect the teeth for damage and tartar, the gums for swelling and inflammation and may want to do some xrays of the head. Tooth root abscesses require removal of the affected tooth and antibiotic treatment, depending on the extent of the abscess.
